Philips JR32RWDV


1. Introduction

Philips JackRabbit32 CD-RW/DVD drive - Page 1

- Introduction

Philips continues the successful JackRabbit portable external product line with the new "JackRabbit 32" CD-RW/DVD combo drive. The new model supports 32x CD-R writing, 10x rewriting and 40x reading, and additionally 12x DVD-ROM reading.

The JackRabbit 32 supports the USB2.0/1.1 interface for fast and easy connection to your notebook/PC, and can also operate as a stand-alone DVD player connected to your TV. In this case the drive is connected through the S-Video or the composite video output straight to your TV-set and is fully remote controlled as a normal DVD player.

- Drive features

The supported writing speeds are the 4x, 8x, 10x and 12x (CLV), the 16x speed and the maximum 32x (Z-CLV). The 40x CAV is the maximum supported reading speed for the CD-R, while the HS-RW (High-Performance ReWritable) media can be written at 10x. The maximum reading speed for DVD-ROM is 12x.

The Philips JR32RWDV supports the USB 1.0/2.0 interface connections. The features mentioned above are valid for the USB 2.0. By selecting the USB1.0 interface (12Mbits/sec), the reading /writing supported speeds are 4x for CD-R and CD-RW writing, 6x for reading and 0.7x for the DVD-ROM format reading.

The buffer underun protection and the 8MB cache buffer will prevent any buffer underun problems in CD-R/RW formats. Seamless Link detects the clues of an imminent buffer underun ahead of time. It pauses the writing in a controlled way, and restarts the writing when the danger of the buffer underun is gone.

Seamless Link technology, however, does not prevent the occurrence of buffer underuns. Seamless Link only acts to prevent buffer underuns from wasting a disc, it can not be used un conjunction with a speed or quality optimization algorithm.

TBW intelligent drive technology, developed and patented by Philips, is a powerful feature that assures data integrity by physically testing each disc, then tuning the output of the recording laser, and choosing the recording speed to suit each individual disc.

Even if the drive determines to use a recording speed lower than the maximum possible, it will always choose the maximum speed which can safely be used for the inserted disc.

Note that the TBW technology is not applicable to the RW function as ReWritable discs utilize a completely different recording methodology than Recordable discs.

The drive is compliant to the RPCII regulations, allowing a user to change the region code of the drive up to 5 times.

 

The dimensions of the drive are 34 x 174 x 130 mm (H x L x W) and its weight is approximately 850gr.

- Blue Button

As in the previous "JackRabbit 24" CD-RW/DVD drive, the JR32RWDV has the "Blue Button" logo. It is a button placed on the right side of the drive. Pressing this button brings up a window with useful access links for several web sites and disc applications.

We installed the software that comes with the installation CD-ROM. After installing, we pressed the Blue Button with the logo next to it on the drive. We could also double-click the Blue Button icon in the Windows system tray or restart the Blue Button program via the 'Programs/Philips external drive' program group. This opened a window with three buttons.

In the interface window, you will see a number of buttons and a menu bar. Clicking the first and the second buttons will open your Internet browser and link you to the Philips PC Peripherals product information web page.

When you click the third button an application program associated with the type of disc in the drive opens. By default, if a CD-R/RW disc is inserted in the drive, clicking the third button will Start a recorder / rewriter application. If a CD-ROM, CD Audio is inserted, a Media Player for an audio disc a Video CD or a disc explorer program for a data disc will be launched. Of course, the application allows the user to determine the preferences associated with the third button.

As a second option, keeping the Blue Button pressed for 2 seconds or more, your Internet browser program is opened and points you directly to a drive support website for downloading the latest firmware for your drive automatically.

- DVD Player

JackRabbit 32 RWDV can be used either as an external USB CD-R/RW/DVD combo, or as a stand alone DVD player connected to your TV set. The drive can be connected through the VIDEO OUT (CVBS) connection to the composite Video input of your TV. However, for the best picture quality you can connect the S-Video cable included with the player between the S-VIDEO OUT (Y/C) connection of the player and the S-Video (Y/C) input of your TV.

The device is controlled by an accurate and handy remote control, included in the package. A complete Menu window is available for controlling the basic features of the DVD playback. The drive supports playback of DVD-Video, DVD+RW, DVD-R, Video-CD & SVCD, CD (CD-R and CD-RW), MP3 and JPG / Kodak Photo CD.

 

- The package

The retail package includes the 32x combo drive, a power supply adaptor, an installation & Software CD with CD Recording software for PC and Mac, and a DVD Video playback software for PC.

A blank CD-RW disc along with a USB 2.0 (USB 1.1 backwards compatible) cable and an instructions manual are also included in the retail package.

For connecting the JR32RWDV to your TV set, you will need an S-Video cable or a Composite Video cable, provided by Philips. For stereo or analog surround sound, an analog audio cable is available in the package while for digital 5.1 channel surround sound, you will need the digital audio cable.

As you can see the main body of the drive is brown, and the Lid Cover (top-opened tray) is silver colored with the "Jackrabbit" logo in the middle of it.

On the front panel of the drive there are three different LEDs. The CD and DVD LEDs light to BLUE when a CD/DVD is loaded in the player. Both the CD and the DVD LEDs light up blue on power up. In the middle of those two LED there is the Status Bar LED, lighting to blue when reading and red when writing.

The RC receiver eye is placed below the LEDs to receive the remote control commands. In addition, the eject and the power buttons are placed in the front panel of the drive. Note that the power button is only valid when connecting the JR32RWDV as a DVD player.

On the side panel there is the power supply connector, a digital audio out for connecting to a digital surround decoder, and the USB 2.0/1.1 interface, for PC use. Audio output can be also analog through the analog audio connector.

The S-Video out provides high quality video output, while the available composite video out (CVBS) can be used optionally as a second video output.

- PC Installation

The JackRabbit 32 was connected to our test PC through the USB 2.0 interface, and was identified as "PHILIPS JR32RWDV" under WinXP. The January 2003 model came with firmware version vP1.3 installed. This is the firmware version we used to make all the reading/writing tests.

We compare the new drive with an already tested combo drive, the INcoder GH32U-A1.


2. Data CD Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 2

Data CD Tests

- Pressed CD results (74min and 80min CD Speed Graphs)

Both Philips JR32RWDV and INcoder GH32U-A1 drives support the 40x CD-R reading speed. The Philips drive gave an average reading speed of 30.71x. Although the drive started reading at 7.94x, it accelerated very fast to 18x at the 1:30 min of the disc! With 74min media, the reading speed by the end of the task reached the 40.32x.

The drive gave low seek times in all three seek modes. It needed 101msec for the random seek and 158msec for the full seek mode. The INcoder drive was slightly faster in the same modes, but the differences should not be considered as important.

- CDR Media results (74min and 80min CD Speed Graphs)

The JR32RWDV read the CD-R disc faster than the pressed one in the previous test. The drive's average speed is 31.73x, as it reached the 42.34x by the end of the process.

In the seek test, the drive was 10msec slower than a pressed disc in the random stroke, and exhibited good performance in the 1/3 and Full stroke tests.

- HS-RW media (Click to see the CD Speed Graphs)

For the RW tests we used the Ricoh HS-RW media. The JR32RWDV supports 40x HS-RW reading speed. The drive was fast and finished with a 31.66x average speed. The INcoder drive is slower due to its lower supported speed.


3. CD Error Correction Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 3

Error Correction Tests

In the following tests we examine the error correction capabilities of the Philips JR32RWDV while reading an artificially defected recorded CD.

- EAC CD-R Test Disc

- Test Results (Max Reading)

The drive starts reporting errors at 8mins. The errors within the black triangle defect, reached -23dB in specific areas. The five scratches also produced errors and the signal/noise level was higher than -18dB(A). The score is of 52.8 out of 100 (max), which is a low performance compared to other drives.

The score for Philips JR32RWDV is 71.6, which is an average performance. The total errors occurred are less than those in the previous test, but the muted samples were less. The drive also gave only 2 skip samples.

- ABEX TCD-726

- Test Results (Max Speed)

The drive gave a very high score of 83.1 points out of 100. Only 4 loudness errors occurred and their level is low, -86.2dB(A) on average. The only skip sample had a length of 257 samples.

Average Score
69.16

The Philips JR32RWDV gets an average score of 69.16 out of 100 in the reading error correction tests. As we have mentioned in previews hardware tests, the EAC tests give a general idea of the behavior of a drive with respect to error correction of defected data discs. An average score should not discourage users for using the specific drive, since it is very hard to achieve 100% success in these tests . However, there were drives that gave better results than the JR32RWDV, mostly IDE ones, thus Philips could definitely work on improving this performance by providing improved error handling on firmware updates.

- C2 Information accuracy

- Test Results (MAX Speed)

The drive cannot retrieve any C2 error information, according to EAC. As a result, the amount of C2 missed equals to the errors occurring when comparing with respect to the original .wav. No sync errors occurred, resulting to an average quality score of 86.2 points.


4. DVD Reading Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 4

DVD reading tests

- Single Layer DVD-ROM reading: (Click for CDSpeed results)

Philips JR32RWDV supports a maximum of 12x CAV reading speed for the DVD format. The drive reached the 12.14x reading speed by the end of the disc, and gave an average speed of 9.17x. The INcoder drive is slower since it supports only 8x CLV DVD-ROM reading.

The seek times of Philips JR32RWDV are higher than we expected. The random seek test gave an average of 123msec, and the Full seek around 213 msec. The INcoder drive seems to be faster in the same tests.

- Dual Layer DVD-ROM reading: (Click for CDSpeed results)

The drive supports 9x CAV reading speed for the dual layer DVD-ROM discs. The average reading speed for each layer is 7.01x, and is faster than the INcoder drive.

The seek times for the dual layer DVD-ROMs are increased for the Philips drive. The full stroke seek gave a 415msec result and also the rest seek results are higher than we could expect. Philips should had chosen a lighter pick-up mechanism in order to obtain a better performance.

- DVD Ripping Tests

We measured the DVD Ripping speed using the "Matrix" DVD Video title and the DVD Decrypter v3.0 software.

The ripping speed of Philips JR32RWDV is high and ripping to the hard disk was made at an average speed of 8828 kb/s. The INcoder drive is slower with just 7284 kb/s, again due to its 8x supported reading speed.

- DVD reading Tests

The chart below shows the Nero CDSpeed results with the following media.

The Philips JR32RWDV read all the inserted discs at an average of 3x. The behavior of the drive was the same with all the discs, starting reading at 1.6x approximately and ending the task on the outer part of the disc at 4x (CAV). The INcoder drive was faster in these tests with an average of 4.6x reading.

The seek times of the Philips drive were slightly worse when using DVD-ROM discs.


5. DVD Error Correction Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 5

DVD Error Correction Tests

In the following tests we examined the DVD error correction capabilities of the Philips JR32RWDV. For the tests we used CDVD Benchmark v1.21 and Nero CD/DVD Speed . The reference test media comes from ALMEDIO.

- Single Layer media

ABEX TDR-821

This is a single sided, single layer DVD-ROM with a 4.7GB capacity, in which there are scratches with dimensions ranging from 0.4 to 3.0 mm. The following transfer rate picture comes from CDVD Benchmark v1.21.

Philips JR 32RWDV seems to have no problem finishing the reading task with no errors. However, the drive did not reach the 12x maximum supported reading speed, and kept it at 6X until the end of the reading process. No read error were occurred.

ABEX TDR-825

This is also a single sided, single layer DVD-ROM with a 4.7GB capacity. The data structure of the disc is exactly the same as the TDR-821, with the difference that there are no scratches on it but some defected areas with dimensions ranging from 0.5 to 1.1 mm. There also fingerprints sized from 65 to 75 micro meters.

The drive did not have any problems to read the disc contents. The yellow dots correspond to the current speed in each area of the disc. No read errors were reported.

- Dual Layer media

ABEX TDR-841

This is a 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches with dimensions from 0.4 to 3.0mm, in both of its layers.

Judging from the reading test with the single layer disc, we might expect the drive to finish the test with no problems. However, with the double layer disc Philips JR32RWDV gave a read error while reading the first layer. Then the drive skipped into the second layer of the disc, which was read with no problems.

ABEX TDR-845

The disc is a single sided, dual layer DVD-ROM disc with a capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first includes defected areas and fingerprints. The dimensions of the defected areas are in the range of 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micro meters.

This time, the drive stopped reading by the end of the first layer of the test disc. The test could not be continued and terminated. It seems that the JR32RWDV needs some improvement in this area.

ABEX TDV-541

The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with capacity of 8.5GB. The disc is based upon the TDV-540 series which is designed for inspection and adjustment of DVD-VIDEO players. The discs check the layer switch operation from layer 0 to layer 1 and also include test pictures and test signals for DVD sound files. The current TDV-541 reference disc checks also the error correction capabilities of the drive and includes scratches from 0.4 to 3.0 mm.

As you can see from the CDSpeed test above, the drive did not manage to finish the reading test. The problems started after reading 2.2GB of the disc, where the drive showed instability while reading and slowed down reading. As a result, the test was terminated in the first layer of the DVD-Video disc.

ABEX TDV-545

The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer DVD-VIDEO disc with a capacity of 8.5GB. The TDV-545 includes artificial black dots on the data surface, sized from 0.4 to 1.0 mm. It has also 65 - 75 micro meter fingerprints.

Black dots and fingerprints were not a problem for the drive. The test was successful, with an 5.71x average speed.


6. CloneCD Reading Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 6

CloneCD Reading Tests

- Procedure

We used CloneCD and 3 original CDs - Serious Sam 2 (SafeDisc 2), V-Rally 2 Expert (SecuROM 2) and NBA Jam Extreme (PSX) - in order to test the reading time of the drives. We also tested the reading performance with backups of the original CDs, since the reading speed varies between original and backup media. The following pictures show the drive's reading/writing capabilities as reported by CloneCD:

- PSX Pressed Media

For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image to the HD with CloneCD. Philips JR32RWDV needed 149 seconds to finish the task, while the INcoder drive was significantly faster.

 

- SafeDisc v.2 Results

The Philips JR32RWDV needed approximately 1:10 min to finish the task. The performance is low and the INcoder drive is faster.

- SecuROM Results

Both drives can read SubChannel data from Data/Audio tracks, but the Philips drive does not support 96 bytes of Subchannel data (CD+G). 3:32 minutes were enough for the drive to make the image file to the hard disk.


7. DAE Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 7

DAE Tests

- DAE features

EAC v0.9 reports that Philips JR32RWDV does not support caching of data and C2 error Info, but supports "Accurate Stream" .

- Pressed AudioCD results

In this test we examine the DAE speed of drive. The Philips JR32RWDV drive ripped the audio files at an average of 20.3x. The ripping speed is low and the INcoder drive is faster (29.3x).

- CDR AudioCD results

With CD-R media, the average ripping speed is again 20.3x, and the INcoder drive is still faster achieving an average of 30.1x.

- EAC Secure Extract Ripping mode

Below we have included the results by using EAC in secure extract ripping mode (which ensures maximum quality produced WAVs). Note that for each drive we used the build-in detection function:

- Advanced DAE Quality

Philips JR32RWDV got a 100 score (best) in the Nero CD Speed Advanced DAE test. The average reading speed for the drive is 20.14x. The drive can also read data from SubChannel and CD Text.

 

- Ripping 90 and 99mins AudioCDs

Recognizes disc contents but not EAC reported timing problems

The drive ripped the tracks of the Key2Audio protected title without any problems. With the Cactus Data Shield disc, it ripped the disc contents but EAC reported that the ripped tracks had timing problems.


8. Recording Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 8

CDR Tests

We tested the drive with the latest version of Nero/CloneCD. Philips JR32RWDV supports the 32X (Z-CLV) maximum writing speed.

As you can see from the CDSpeed graph below, the drive does not keep the writing speed steady even in the areas where writing is done under the CLV mode. Sequential decreases /rises in the writing speed occur, in the areas where someone might expect the graph to be horizontal. These fluctuations result to a 24.73x average writing speed, and the duration of the writing process is expected to be influenced by the specific writing strategy. The basic speed shifts are from the 16x to 24x at 14min, and up to 32x at 44min.

- Recording Tests

We burned 80 minutes of data with both drives. As you can see, Philips JR32RWDV needed 252 seconds to finish the task, and the duration seems to be rather high for a 32x recorder. The explanation for this can be found in the CDSpeed graph above, where you can see the Z-CLV implementation of the drive. The following picture comes from Nero after a successful burning at 32x.

The following is from Nero again after a burning task at 16x.

Below you can see the best recording times we obtained for all the supported writing speeds. The Philips drive is slower than the INcoder at 32x. Note that Philips JR32RWDV does not support the 24x writing speed at all.

- Other features

Overburning
Up to 89min
CD text reading/writing
Yes

- CloneCD Writing Tests

The CloneCD software reports that the drive supports the DAO-RAW feature. In some cases the drive didn't worked properly with specific media.

For checking the drive's EFM correction status, we used 3 different game titles with different SafeDisc 2 versions and all the latest software patches installed. We used the drive as both a reader/writer at maximum reading/recording speeds. Two discs were burned for each game (Amplify Weak Sectors On/Off). One disc was burned with PadusDJ and the other with CloneCD (Amplify Weak Sectors On). The results are posted in the table below:

Game Title

The Philips JR32RWDV cannot handle SafeDisc v.2.60xx or higher protected discs. Amplifying weak sectors did not make any difference. The drive created working backups of SD v2.50.020 that played in all drives we tested them.


9. Writing Quality Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 7

Writing Quality Tests

We used Taiyo Yuden 80min 48X CD-R media and burned the same AudioCD project (with CD-Text) at all recording speeds between 4x-32x. Below you can see the 3T Pit & Land Jitter graphs.

- 3T Pit results

As we can see from the above graphs, the 3T Pit Jitter stays below the 35ns Red-Book limit for all the available recording speeds, except for the 4x case. In this speed, the jitter value reached 38nsec at the 55-60min playback of the disc. However, the value is not very high and it is lowering again by the end of the disc. Generally, the results are adequate and it seems that there will be no problem writing even at the maximum 32x speed.

The average 3T Jitter values for all recording speeds are illustrated in the following table.

The 16x writing speeds gave the lowest average jitter values, and the 4x the highest. The average value of jitter is less than 35nsec for all the recording speeds. Since the differences in the average jitter values is very small, we can claim that you can safely burn your favorite audio discs in any available speed.

- 3T Land results

The 3T Land results are slightly increased over the previous measurements of the 3T Pit Jitter. The maximum jitter values reported were 39ns, and come from the measurements on 4x recorded disc.

- Conclusion

The average 3T Pit and Land jitter values are below the 35nsec standard for all the recording speeds. The 4x recorded discs gave some slightly increased values but it seems that they cannot influence the overall quality. The combination of low writing speeds and the CLV writing technology seems to guarantee the quality of the results. We may also see that the Z-CLV technology adopted for 16x and 32x speeds does not affect the writing quality.


10. HS-RW Writing Tests

Philips JackRabbit32 CD-RW/DVD drive - Page 8

HS-RW Writing Tests

We used Nero Burning Rom for writing CDs in the maximum RW speed supported by the Philips JR32RWDV. The drive supports 10x maximum rewriting speed.

It finished writing in 8:02 minutes, and needed 28 seconds to perform the "quick erase" task with Nero. The INcoder drive is slightly faster by 6 seconds.

- Packet Writing Tests

We used InCD and Ricoh HS-RW media for all Packet Writing tests. The formatting of the media takes around 10min. The formatted disc had 530mbs of free space. We copied a 403 MB file (403.147 kbs) from a Hard Disk (attached on the same PC as the writer) to the formatted RW media, using windows explorer (we dragged and dropped). We carried out the test twice to eliminate possible time measurement faults and user errors:

In the writing part, both drives gave the same result (6.92x), which is reasonable for 10x rewriting. In the reading part the Philips drive is slower than INcoder GH32U-A1, although the second drive exhibited lower CD-RW reading in the transfer rate tests.

- Mt. Rainier Tests

For testing the Mt. Rainier performance, we used InCD from Ahead Software. After the format process, we started the recording process (drag & drop). When the drive finished, we started the reading process back to the HD.

Philips JackRabbit 32 is a fast portable CD-RW/DVD-ROM combo drive with a unique feature for its category: It can be used either as a fast CD-RW/DVD combo attached in your PC/notebook or just as a separate stand-alone DVD player connected straight to your TV set. The device is fully remote controlled and offers nothing less than your home DVD-Player, allowing navigation and easy setup of the player through a smart Menu on your TV screen.

The package is complete and includes all the essential connection cables and manuals for PC-based or stand alone operation of the drive. PC connection is achieved through the USB2.0/1.1 interface.

The JR 32RWDV supports the 32x Z-CLV maximum recording speed for the CD-R format. Our tests showed that the current implementation of the Z-CLV technology does not allow the drive to achieve the lowest writing times among the 32x category drives. However, the writing stability is very good and no writing problems occurred while writing on various media. In addition, the Jitter measurements on the recorded media showed a high writing quality.

In the reading part, the drive is fast and the reading speed reached the supported 32x, both using pressed and CD-R media. The seek times for the CD format is low, but the ability to correct possible faulty bits on defected and scratched media (Almedio Abex) could definitely be higher. The drive also cannot retrieve any C2 error information while reading.

The supported average DAE speed is approximately 22x but it could be higher. The drive can also handle Key2Audio protected audio discs but does not read accurately the tracks of a Cactus Data Shield 200 disc. The reading /writing of CD-Text on audio discs is also supported.

CloneCD users will not be satisfied by the lack of the drive's ability to create working backups of SafeDisc v.2 protected titles, and the reading speed is generally low. Reading of 96 bytes of SubChannel data is also not supported.

As for the DVD format, the drive supports reading of DVD-ROM (single layer) at 12x CAV, and also supports reading of DVD-R/RW and DVD+R/RW discs at 4x on the average. However, the DVD error correction tests with ABEX test media showed that the drive had some problems with scratched and defected DVD-ROM discs, producing some read errors. The problem seems to be more serious with the ABEX dual layer DVD-ROMs, where the drive stopped reading the disc and refused to continue the test. Seek times on Dual layer DVD-ROMs were also higher .

The Philips JackRabbit 32RWDV left us with a positive overall impression. Although the drive did not gave perfect results in all the tests, it performed adequately in the basic benchmarks, with an exception in the reading of dual layer DVD-ROMs. The retail package is available at a street-price of about $235.
