Ricoh MP5308D


1. Retail Package - Installation

Ricoh MP5308D DVD±R/RW Recorder - Page 1

as a member of the DVD+RW Alliance produced one of the first DVD+R/RW recorders, the MP5120A. Its successor, the MP5125A was a hot selling drive for quite long time, until most manufacturers developed their own DVD recording solutions. In the meantime, Ricoh made several alliances (Funai Electric etc) in order to further develop DVD recording technology. However, for quite sometime Ricoh did not produce any other drive, at least not with any interesting features.

After this year's CeBIT, we had the chance to see a new 8X DVD±R/RW recorder from Ricoh with the codename "MP5308D". The drive's specs were promising and we soon had the drive in our labs and under the microscope for testing. Today we present a review of the drive, with the usual basic information and results from our burning tests for both CD/DVD formats.

- Drive specifications

The MP5308D is an 8X DVD±R, 4X DVD±RW, 32X CD-R and 16X CD-RW writer. In addition, it supports 12X DVD-ROM and 40X CD-ROM reading specifications. The specs are more or less the same with other well known models on the market, so it would be interesting to see how it compares with the competition. But first lets take a look at the full specs:

NeroInfoTool gives us a quick look at the drive's capabilities. The drive uses a 2MB buffer memory, supports buffer underrun technology for both the CD and DVD formats, RAW DAO 96 writing (CD), and its firmware is v1.B2 that was used for all the recording tests. Mount Rainier support is excluded as happens in most cases of late, since it appears this technology will probably not be developed further.

DVDInfoPro gave us some additional details about the drive's abilities:

- The package

The drive arrived at our labs without cables, software or media. The retail package includes Nero 6.0 OEM, InCD4 and Nero Vision Express 2. The price of the drive is around €140 according to Ricoh's website. The price in retail shops is expected to be lower.

The drive itself looks like an ordinary "Ricoh" drive with the brand name, codename and CD-RW, DVD-R/RW and DVD+RW logos. There's a single activity led for reading/writing indication, along with the emergency eject hole.

On the label of the drive can be seen the manufacturing date (February 2004) and the manufacturing line (Made in Malaysia)

After removing the bottom plate, we can see the internal structure of the drive. The main chipset comes from NEC and the whole design looks very similar to the NEC 2500A drive. You might notice the label "2100" on the board, that indicates the basic board used to develop the 2500A series.

Click for high resolution image

The drive was installed as a secondary master and under WindowsXP recognized as "RICOH DVD+RW MP5308D". Below is a picture from Nero Burning Rom, showing the drive's specs.

- Testing software

In order to perform our tests we used:

  1. Nero CD-DVD Speed v2.20
  2. Nero Info Tool v2.11
  3. KProbe v2.1.0 (Reader: LiteOn SOHW-812S firmware vUSOJ, Reading speed 4X CLV)
  4. PlexTools v2.14 (Reader: Plextor Premium firmware v1.05, Reading speed 8X CLV)
  5. DVDInfoPro v2.47
  6. Nero Burning Rom v6.3.1.10

2. Transfer Rate Reading Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 2

Transfer Rate Reading Tests

- CD Format

The Ricoh drive supports up to 40X reading speed. Below are the transfer rate graphs compared with two more drives:

As we can see from our tests, the drive behaves similarly to the other two, having acceptable transfer rates and seek times.

- DVD Format

The drive offers good transfer rates with SL (Single Layer) DVD-ROM media.

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, towards the outer range, for each layer. Ricoh has a good average transfer rate.

Click for full graph

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks toward the inner part of the disc. The average reading speed is 5.40X.

Again the Ricoh drive performed similarly to the other two drives, offering acceptable transfer rates with DVD media.

DVD video DL ripping performance wasn`t quite so good, offering only 3044 kb/s.

3. CD Error Correction Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 3

CD Error Correction Tests

In the following tests we check the drive's behavior when it comes to reading scratched / defective discs. The test discs we use are the ABEX series from ALMEDIO.

- ABEX TCD-721R

Ricoh performed poorly with the ABEX TCD-721R. The drive's average error loudness was at -75.2 dB(A) and the total score of 65 points isn`t good. The total error count of 3205447 is very high and there were 20 skipped samples. We must also note that C2 accuracy reached 99.6%, an almost perfect score.

- ABEX TCD-726

Errors total
Num: 4278
Errors (Loudness) dB(A)

C2 Accuracy
100 % (out of 100.0% maximum)

Ricoh had better performance with ABEX 726 disc with total score of 82.3 %.

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction / Error correction capabilities of a CD player. The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively difficult tests. These tracks are referred as Check Level-1 through Check Level-5.

The files are reproduced (played) through a software multimedia player (i.e. Windows Media Player). Each level is considered as passed, if the tone coming out from the speakers is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested device.

Error Level
1
2

0/5

The drive passed only the first two Check Levels of the test. The performance reveals lower than average sound reproduction and error correction. The fifth level includes an error size of 1.500mm, where the drive produced many audible clicks.

- Conclusion

The overall performance of the Ricoh MP5308D was rather poor, since when the drive encounters even small scratches produces large spikes and can't correct them. NEC should really improve the drive's performance, by fine tuning the firmware.


4. DVD Error Correction Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 4

DVD Error Correction Tests

In the following tests we examined the DVD reading capabilities of the Ricoh drive with scratched / defective DVD media. For the tests we used CDVD Benchmark and Nero CDSpeed . The reference test media come from ALMEDIO.

- Single Layer media
ABEX TDR-821

This is a single sided, single layer DVD-ROM with 4.7GB capacity, and its surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm. The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer rate test.

The Ricoh MP5308D read the disc at 12X CAV and the scratched area did not affect the process. The disc was read accurately and no read errors were reported. The performance reveals high error correction capabilities with scratched single layer DVD-ROM discs.

ABEX TDR-825

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

As in the previous test, the disc was read without any "read errors". The test was finished successfully without errors.

- Dual Layer media
ABEX TDR-841

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

The drive didn't have any major problems as the above graph shows.

ABEX TDR-845

The disc is a single sided, dual layer DVD-ROM disc of 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 range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micro meters.

The test was finished successfully without errors.

ABEX TDV-541

The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a 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 checks also the error correcting capabilities of the drive and includes scratches from 0.4 to 3.0 mm.

Click for full graph

The reading process started at 3.42X and reached 4.59X at the 4.0GB point, where the drive changed layer and reduced its reading speed till the end. No serious problems were noticed and the result is good.

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 meters fingerprints.

Click for more info

Black dots and fingerprints on the disc's surface did not create any reading problems, and the drive finished the task successfully.


5. Protected Disc Tests

The Ricoh drive had satisfactory performance.

- Writing Tests

The Ricoh MP5308D supports the DAO-RAW writing mode. For checking the drive's EFM correction status, we used 3 different game titles with different SafeDisc 2 versions having the latest software patches installed. After making the images of the various titles onto the hard disk, we burned them (maximum speed) with Alcohol 120% v1.9.2.1705. Two different discs were created for each title; one with the "Bypass EFM error" enabled and one more with the function disabled.

The table below shows the results of the attempted backups and whether they worked (game installed / played normally), or not.

6. DAE Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 6

DAE Tests

- Pressed and CDR AudioCD

The Ricoh MP5308D supports up to 40X CAV DAE speed. When using a pressed AudioCD and its CD-R copy, with EAC, we logged the following results:

Ricoh was slower than the other drives with the test discs. As EAC reports, the drive can`t cache DAE but supports accurate stream and reports C2 error information.

- Advanced DAE Quality

Ricoh received a score 99.1% in the Nero CD Speed Advanced DAE test. CDSpeed showed that the average reading speed is 24.2X, and that the drive supports reading of CD Text and SubChannel data. Read Leadin / Leadout data are not supported.

7. Protected AudioCDs

Ricoh MP5308D DVD±R/RW Recorder - Page 7

Protected AudioCDs

For the test procedure we used three audio discs with different audio copy protections. The ripping process performed for all protected Audio discs performed with Exact Audio Copy v0.9beta5.

The tested protected Audio discs were:

The Cactus Data Shield 200, contains artificial errors that are not easy to bypassed from the reader, while the Key2Audio contains a second session, causing problems to readers when try to read the Table Of Contents (TOC).

The tested tasks are:

Ricoh recognized up to the 12th Audio track of CDS200 disc,

and with the "Retrieve Native TOC" option removed the 13th Data track.

The test results are shown in the following table:

Key2Audio
CDS200
Ricoh MP5308D
Ripping process completed, EAC reports no problems, Read&Test CRC comparison successful for all tracks
Ripping process completed, EAC reports no problems, Read&Test CRC comparison not the same for all tracks

The Ricoh will rip both Key2Audio and CDS200 protected audio discs. Both discs were recognized and their contents were ripped at the maximum speed. However, the drive may not rip 100% accurately, the CD200 discs since Read&Test CRC check comparison was not the same for all tracks. No problems were noticed with Key2Audio discs.

This is a "special" CDS200 build, since it doesn't contain any artificial errors during the ripping process. Most problems occur when trying to write the ripped wav files, since the produced CD-R disc contains C2 and CU errors! This "problem" is rumored to be connected with specific chipset weaknesses..

We ripped the disc contents with EAC and burned the produced wav with the latest Nero version as AudioCD+CD-Text. The burned media was checked for C1/C2 errors with PlexTools/KProbe software using Plextor PX-712A (firmware v1.01).

CDS 200.0.4 - 3.0 build 16a
Ricoh MP5308D
Reading and writing performed without any error

The C1/C2 error graphs shows that the drive manage to produce a 100% error free disc.

Lets try to extract all wav files with the Plextor PX-712A and PlexTool DAE Error Correction 5th Level enabled:

No errors were reported after extracting all files. The drive's error correction mechanism corrected all errors.


8. CD Recording Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 8

CD Recording Tests

The Ricoh MP5308D supports 32X CD-R and 16X US-RW recording speeds.

The drive supports 4X, 8X, 16X, 20X, 24X and 32X writing speeds. Below are the recording speeds as detected by Nero Burning Rom.

According to Nero CDSpeed, the drive reached the maximum 32X speed. The test started at 15.99X and finished at 32.07X having an average speed of 27.35X. Click on the image below to see the whole graph.

Click for full graph

For the burning tests we created an 80min data compilation through Nero Burning Rom, recording the data on a 700MB disc. Ricoh finished the task in 3:39 minutes, for the maximum 32X writing speed.

The writing performance varies according to the inserted media, as our tests showed. Below is a chart demonstrating all recording times with various media.

The best performance came with Mam 80min 52X & CMC Magnetics 80min 48X media with 219secs (3:39mins). The highest recording time comes with TraxData 80min 52X media with 224secs (3:44mins).

- Other features

Overburning writing
No
CD text reading/writing
Yes

The MP5308D supports the 4X, 8X and 16X rewriting speeds, with Ultra Speed Rewritable Media (US-RW).

Below you can see the Nero CD-DVD Speed writing simulation test with blank 24X US-RW media from Mitsubishi Chemicals.

Click for full graph

The drive starts the writing task at 15.99X under CLV mode.

We also used Nero Burning Rom in order to burn a data disc with 24X US-RW media from MCC. The data compilation we burned had a size of 651 MB and the duration of the recording process was 5:12 minutes.

- CD-RW Mount Rainier

The Ricoh MP5308D doesn`t support the Mount Rainier feature.


9. 3T Jitter Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 9

3T Jitter Tests

On this page you can see the 3T Pit & Land Jitter graphs using various media burned at 32X CAV writing speed.

- 3T Pit results

The Ricoh drive performed satisfactorily with most media used. The highest average 3T Pit jitter reached 51.44 nsec with TraxData media, which is way above the Red Book limit (35nsec). The best results came with CMC 48X CD-R media.

- 3T Land results

The average 3T Land results were also low. The maximum avarage 3T Land Jitter reached was 48nsec with TraxData and again CMC 48X CD-R media produced the best results.

On the following page we check the C1 and C2 error rates of the same discs, to come up with more specific conclusions.


10. C1 / C2 Error Measurements

Ricoh MP5308D DVD±R/RW Recorder - Page 10

C1 / C2 Error Measurements

We measured the C1 / C2 error rate on the recorded discs we burned at the various supported writing speeds. The software we used is PleXTools Professional v2.14, and particularly the built-in Q-Check utility. The reader was the Plextor PX-712A (firmware v1.01)

Maxell 80min 48X CD-R @ 32X (SmartBurn Enabled)

CMC Magnetics 80min 48X @ 32X (SmartBurn Enabled)

Mam Golden Dye 80min 52X @ 32X (SmartBurn Disabled)

TraxData 80min 52X @ 32X (SmartBurn Enabled)

TY 80min 48X @ 32X (SmartBurn Enabled)

- Summary

The MP5308D needs to improve its writing quality with CD-R media. With specific media we noticed high C1/C2 errors, while with Taiyo Yuden 48X & Mam 52X the C2/CU errors were incredibly high. CMC 48X & TraxData 52X had best results.

11. DVD Recording Tests

Ricoh MP5308D DVD±R/RW Recorder - Page 11

DVD Recording Tests
- Writing Performance

The Ricoh MP5308D supports DVD-R/RW and DVD+R/RW writing. The maximum supported speed for the DVD±R is 8X P-CAV and 4X CLV for DVD±RW media. Nero Burning Rom reported speeds, are shown below.

Below are listed the media codes supported for the ±R/RW formats with recording speeds:

By using Nero CD-DVD Speed's "create disc" function with Plextor's 8X DVD-R media, we are able to see the 8X Z-CLV recording technology being used by the MP5308D recorder.

Click for full graph

The drive starts writing at 3.96X until 0.85GB where it shifts up to 6X, until 2.2GB where it further shifts to 8X and stays there till the end. The average writing speed is around 7.14X. This recording strategy is used for both DVD±R formats.

- Burning Tests

We burned 4315MB of data on various DVD±R, DVD±RW media. We used the maximum allowed writing speed for each disc. The best recording times for the DVD-R format came from MKM/Verbatim 8X & MCC 4X media with 9:20mins.

With DVD+R media, best recording time came from Mitsubishi Kagaku 8X with 9:15mins. Also Ricoh didn`t managed to overburn DVDs.

- DVD Overburning Tests

In order to test the drive's DVD overburning capabilities, we used two media types, one from CMC 4X DVD-R and one from Plextor's 8X DVD+R. As you can see, the drive refused to start the test with DVD-R media,

while with DVD+R, the test started but when it reached 4.38GB, stopped with an error message.

Thus Ricoh cannot overburn with either DVD±R formats.

- DVD+MRW Tests

Ricoh MP5308D doesn`t support the Mount Rainier feature.


12. KProbe/PlexTools Scans - Page 1

Ricoh MP5308D DVD±R/RW Recorder - Page 12

KProbe/PlexTools Scans - Page 1

In the following screenshots you can see the PI/PIF scans for the DVD+R/RW media we burned with the Ricoh MP5308D. The software we used for all measurements is the KProbe v2.1.0, and the reader is the LiteOn LDW-811S with "HS0Q patched" firmware, being able to read DVD±R/RW media up to 8X CAV. All scans have been performed at 8X with PI/PIF Sum8. Note that LiteOn drives cannot report PO but PIF errors, despite what KProbe reports. In addition, all discs have been scanned with PX-712A v1.02 using PlexTools v2.14 for comparison levels.

Comparing the KProbe/PlexTools scans we can see major differences in the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combinations, scanning at different reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). It's interesting to see the disc scanned at low & high speed, since when error rate increases at a specific disc area, it should appear in both scans...else it would be, perhaps, a reading glitch of the tested reader.

Note: PI/PIF errors only give us a quick look at the error rate of the burned media. Those scans should be taken not as the absolute criteria of the burning quality but as an indication.

KProbe/PlexTools Scans - Page 2

In the following screenshots you can see the PI/PIF scans for the DVD-R/RW media we burned with the LiteOn SOHW-832S. The software we used for all measurements is the KProbe v2.1.0, and the reader is a LiteOn LDW-811S with "HS0Q patched" firmware, being able to read DVD±R/RW media up to 8X CAV. All scans have been performed at 8X with PI/PIF Sum8. Note that LiteOn drives cannot report PO but PIF errors, despite what KProbe reports. In addition, all discs have been scanned with PX-712A v1.02 using PlexTools v2.14 for comparison levels.

Comparing the KProbe/PlexTools scans we can see major differences at the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combination, scanning at different reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). Its interesting to see the disc scanned at low & high speed, since when error rate increases at a specific disc area, it should appear at both scans...else it would be, perhaps, a reading glitch of the tested reader.

Note: PI/PIF errors only give us a quick look at the error rate of the burned media. Those scans should be taken not as the absolute criteria of the burning quality but as an indication level.

- Summary

Ricoh creates DVD-Rs with low PI/PIF error levels and offers compatibility with the majority of the media we use. Only with N-Star 4X & Vanguard 4X the writing quality isn`t acceptable with high PI/PIF error level.

15. Conclusion

Conclusion

The Ricoh MP5308D performed well having low seek times in the CD reading tests. The error correction test results however, showed below average performance.

DVD reading is fast with both recordable and pressed media, along with good seek times. The drive further displayed very good error correction capabilities with the defective discs. The drive managed to playback all of our test discs without reporting any errors or problems, which means strong DVD error correction capability.

The drive offers poor performance with our protected games CDs. The drive doesn't support the latest SafeDisk2 versions and partially working backups are playable with SafeDisc v2.51.051 and EFM off. Full support occurs only with SafeDisc v2.51.020 and EFM off. Ripping times of various protected game titles was acceptable.

The drive returned good performance with the CDS200 protection scheme as the ripping process completed with no problems but reading & testing CRC comparison was not the same for all tracks. Key2Audio protection ripping process completed with no problems as well as reading & testing CRC comparison. Reading and writing was performed without any error for Cactus Data Shield 200.0.4 - 3.0 build 16a (Aiko Katsukino - The Love Letter). The drive could not play our 99min AudioCD but read the 90min CD.

When writing CDs with the Ricoh drive, we had poor writing quality with three out of the five media we used. The drive creates CDs with high C1/C2/CU errors and we also suggest avoiding Taiyo Yuden 48X media with this drive as it gave us the highest jitter results and C2/CU errors. We expect that all this will be fixed with a new firmware upgrade. Best results with low jitters & C1/C2/CU were with CMC 48X media.

DVD recording revealed that the drive has good media compatibility with all media except with Bulkpaq 4X DVD-R burned at 4X speed, N-Star 4X DVD-R & Vanguard 4X DVD-R. The recording quality is good with low PI/PIF error levels.

The drive priced at about $112.
