Pioneer DVR-112


1. Introduction

Pioneer enters the 18x DVD recording market with a new Super-multi DVD burner. The Pioneer DVR-112 DVD/CD writer will burn at a maximum speed of 18x with DVD-R/+R single layer media, up to 12x on DVD-RAM Ver2.2 [RAM2(Class1)] media, and is the first DVD burner that writes up to 10x on DVD-R/+R (DL). The drive is available in beige and black (DVR-112BK) in Europe as an OEM, while it is also available in Japan (retail version).

Pioneer has also released another version of the drive, without writing support for DVD-RAM, the DVR-112D (DVR-1810 in the U.S.).

Pioneer engineers claim that the DVR-112's combined specifications deliver one of the highest levels of all-round DVD-writing performance and quality currently available.

Let's take a look at the drive's specifications, which appear to be quite impressive.

Key features DVR-112
  • Writes and reads DVD-RAM, DVD-R/RW, +R/RW and CD-R/RW formats
  • Buffer under-run protection for CD/DVD
  • Performance Adjusting Firmware - automatically optimises the disc’s rotation speed depending on the user’s application – for example, if watching a movie or listening to music, the disc velocity is reduced in order to keep background noise to a minimum.
  • Multi-effect Liquid Crystal Tilt Compensator - further improves recording and playback characteristics by compensating for discs that are warped or of uneven thickness (operates at high speeds and with Dual/Double layer discs).
  • Ultra-DRA (Dynamic Resonance Absorber) - suppresses vibration caused by imbalanced discs.
  • Disc-Resonance Stabiliser - controls the airflow generated by the disc-rotation to minimise disc-warping effect that can occur when a disc rotates at high speed.
  • Max. 18x writing speed for DVD-R/+R*
  • Max. 10x writing speed for DVD-R DL (Dual Layer) and +R DL (Double Layer) Discs
  • Max. 6x writing speed for DVD-RW

    The drive

    The beige version of the DVR-112 is illustrated in the pictures below.

    Our test sample was manufactured in China in December 2006.

    This drive is built on the NEC MC-19041Chipset.

    Installation

    The Pioneer drive was connected as a typical IDE drive and was recognized as "PIONEER DVD-RW DVR-112 ". For the tests we installed the latest v1.09 firmware, available from Pioneer Europe here .


    2. CD/DVD Reading tests

    For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of Pressed CDs. The drive can read CD media at a maximum speed of 40X. For reference, we present a comparison of the Pioneer DVDRW drive with the LiteOn LH-20A1P, Memorex 525GE and Samsung SH S182D drives.

    US RW CD

    The following CD Speed graph shows the reading performance with US-RW media. For all the CDSpeed graphs, you can click on the image to see the full CDspeed snapshot.

    Press for Larger Picture

    - AudioCD

    In the CD Speed Advanced DAE quality test, the drive's average speed was 26.67X with a quality score of 100.

    A typical DAE task with an 80min non-protected Audio CD produced 29.4X average ripping speed.


    - 90/99 mins Audio disc

    Both the 90min and the 99 min audio CDs produced an error, as you can see in the screenshots above.

    - DVD Format

    Now let's have a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 16X maximum speed for single layer DVD ROM and at 12X for dual layer DVD ROM media.

    DVD-ROM SL media -

    PTP DVD-ROM -

    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, progressing towards its outer range.

    The Pioneer drive is the fastest in this task.

    OTP DVD-ROM -

    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 and progresses towards the inner part of the disc.

    Again, the DVR-112 is fastest.

    3. CD Error Correction

    In the following tests, we check the drive's behavior when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

    - ABEX TCD-721R

     

    Errors total Num: 1171052
    Errors (Loudness) Num:56942 Avg: -73.4 dB(A) Max: -34.9 dB(A)
    Error Muting Samples Num:3684 Avg: 1.0 Samples Max: 40 Samples
    Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
    Total Test Result 76.5 points (of 100.0 maximum)

    A good score for the Pioneer drive with the scratched audio CD.

    - ABEX TCD-726

    Errors total Num: 870
    Errors (Loudness) dB(A) Num:47 Avg: -66.4 dB(A) Max: -50.4 dB(A)
    Error Muting Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
    Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
    Total Test Result 92.0 points (out of 100.0 maximum)

    The performance is average here, with the drive reporting errors quite early on. But the severity of the errors (level) is low, meaning that no audible problems will make it to your speakers, at least with these types of defects.

    - CD-Check Audio Test Disc

    The CD-Check Test Disc is another 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 more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

    The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.

    Error Level
    1
    2
    3
    4
    5
    Pioneer DVR-112
    5/5
    5/5
    5/5
    5/5
    0/5

    The drive achieved flawless reading with the first 4 tracks. Playing the fifth track produced audible sound interruptions and clicks.

    - Summary

    Overall, the drive appears to have acceptable CD Error correction capabilities.


    4. DVD Error Correction

    In the following tests, we examined the DVD reading capabilities of the drive with scratched / defective DVD media. For the tests, we used CDVD Benchmark and Nero CDSpeed. 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, 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.

    Respectable reading with no read errors from the Pioneer drive.

    ABEX TDR-825

    This is also a single sided, single layer DVD-ROM of 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 instead, defective areas of dimensions ranging from 0.5 to 1.1 mm.

    There are also fingerprints sized between 65 and 75 micrometers.

    No issues for the DVR-112 drive, continuing its good performance:

    - Dual Layer media

    ABEX TDR-841

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

    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 defective areas and fingerprints.

    The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.

    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 disc checks the layer switch operation from layer 0 to layer 1 and also includes test pictures and test signals for DVD sound files.

    The current TDV-541 also checks the error correcting capabilities of the drive and includes scratches from 0.4 to 3.0 mm.

    This is not the expected behavior from the Pioneer drive. The second layer of the disc was read at a much lower speed, in order to compensate the reading difficulties with the test disc, as the artificial scratch gets wider towards the end of the data addresses. Despite the difficulties, the drive finished the test.

    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 also has 65 - 75 micrometer fingerprints.

    - Summary

    Overall, a good error correction mechanism with DVD media.


    5. Ritec CD-R

    For this test, each CD-R disc was burned to its maximum capacity and at its maximum speed. Then the same disc is read with the CDSpeed software, and the disc was scanned for digital errors (BLER, C1 and C2) with our system provided by Clover Systems. To simplify the presentation, we present the BLER, E31 and E32 error rates for each disc, which unveil the most serious errors on each disc.

    - About Clover Systems

    The Clover Systems CDX Compact Disc Analyzer is a tool to quantitatively measure the quality of a CD. It will analyze CD-DA, CD-ROM, CD-ROM XA, CD-I, CD-R, Photo-CD, Enhanced CD and CD-RW discs at 4X, 8X, 24X, 32X or 40X speed. It effectively measures disc quality by examining the quantity and severity of CIRC errors generated during playback. It also provides the capability to measure signal parameters related to pit geometry, such as asymmetry and reflectivity. Together, all these bits of information provide a thorough analysis of disc quality. The Clover Systems Analyzers can also perform various format-checking tests on data discs, and do bit-for-bit data comparison on all types of CDs. All tests are carried out at the speed of 4X.

    CIRC error correction uses two principles to detect and correct errors. The first is redundancy (extra information is added, which gives an extra chance to read the disc), and the second is interleaving (data is distributed over a relatively large physical area). The CIRC error correction used in CD players uses two stages of error correction, the well known C1 and C2, with de-interleaving of the data between the stages.

    The error type E11 means one bad symbol was corrected in the C1 stage. E21means two bad symbols were corrected in the C1 stage. E31 means that there were three or more bad symbols at the C1 stage. This block is uncorrectable at the C1 stage, and is passed to the C2 stage. Respectively, E12 means one bad symbol was corrected in the C2 stage and E22 means two bad symbols were corrected in the C2 stage. E32 means that there were three or more bad symbols in one block at the C2 stage, and therefore this error is not correctable.

    BLER (Block Error Rate) is defined as the number of data blocks per second that contain detectable errors, at the input of the C1 decoder. Since this is the most general measurement of the quality of a disc, you will find BLER graphs for all media tested below. If you click on the images you can see a more detailed table, indicating error levels. The Red Book specification (IEC 908) calls for a maximum BLER of 220 per second averaged over ten seconds. Discs with higher BLER are likely to produce uncorrectable errors. Al low BLER shows that the system as a whole is performing well, and the pit geometry is good. However, BLER only tells us how many errors were generated per second, and it does not tell us anything about the severity of those errors.

    Reading speed 25.46X Average

    Writing Quality - Clover Systems

    An overall nice burn, with no uncorrectable errors.


    9. The DaTARIUS DVD Analyzer R 2x

    The DaTARIUS DVD Analyzer R 2x is one of the cornerstones in DVD quality control equipment, and is truly unique in the industry. It allows checking of replicated DVDs with single and dual layer structure (DVD-5, DVD-9, DVD-10, DVD-14, DVD-18) and written DVD recordable, at 1X and 2X speed. It is based on the Pulstec Reference Pickup and Drive, developed in close co-operation with Pulstec and according to the standards of the DVD Forum.

    In short, the device's features include:

    An explanation of the various parameters the DaTARIUS DVD Analyzer R 2x offers is available here. At the same page, you can read more details about the error signals and a brief analysis the possible meaning of its parameter in the overall quality of each burn.

    In the following pages, we present the writing quality measurements of various DVD recordable and rewritable media, burned with the Pioneer DVR-112 DVD burner.


    10. CMC MAG M01 (000) DVD+R

    We start our DVD writing quality measurements with DVD+R media. A variety of different MIDs were selected and were burned at the maximum allowed speed. In each of the following pages you can find detailed information about each disc, the burning and reading procedure as well as the related signal measurements that construct the overall quality picture of each disc.

    You can always navigate across the different MIDs of this test, using the page navigation drop down menu.

    DaTARIUS Scans -

     

    According to the measurements, increased PISum8 errors were reported at the addresses where the drive jumped to higher recording speeds in the Z-CLV writing strategy. Very high digital errors were reported at the 44mm radius of the 4.7GB disc, where the recording speed was increased to 12x. In addition, jitter was beyond limits at the same positions. However, no POF (uncorrectable) errors were reported, and the disc was readable.

    As we have mentioned on several occasions in past reviews, the limits for the various measurements are quite strict. So a "negative" result does not always mean that the disc is unreadable. But certainly, the amount of PISum8 errors reported here is high and could lead to uncorrectable errors on important discs, such as for archiving.

    The measurements are summarized in the below table. You can see the limits for each signal, the average and maximum value as it was reported by the DaTARIUS equipment and the values at three specific positions on the disc (radius 25.0mm, 40.0mm and 55.0 mm)

    About Almedio AEC-1000

    The AEC-1000 consists of a DVD Drive and the "ALChecker" error measurement application which can check the written data quality. The application is capable of 1X CLV measurement as well as 4X CLV on DVD-Video/ROM and finalized DVD+R/-R media.

    There are three measurement modes:

    The checking status is shown graphically in real time while you can save the error graph at the end of the test. The reported errors are the PI and the UncPO. In the case of PI, it counts the number of rows corrected by the PI error correction in each group of eight consecutive ECC blocks. In the case of UncPO, it counts the number of ECC blocks in which more than one byte is uncorrectable in eight consecutive ECC blocks. For our quality scans, we set for 1X CLV and Fine Mode which is the slowest and with the safest results. Also, we chose to measure all the media burned at the maximum available writing speed.

    - Booktype Settings

    The DVR-112 does not support the Booktype feature with DVD media..

    - DVD Overburning

    The Pioneer drive does not support overburning with DVD recordable media, according to CDSpeed.


    36. Conclusion

    Pioneer has been a respected company in optical storage, thanks to its high-quality DVD burners. But this time, the DVR-112 left us with some doubts and failed to fulfil our expectations.

    The drive appeared to have satisfactory CD and DVD error correction capabilities, although at times it needed to slow down in some extreme cases, in order to cope with the defective DVD media. The output however, was reliable enough. So the Pioneer DVR-112 can do the job with those slightly damaged CDs and DVDs.

    The relatively low reading speeds of 12X for DVD±R and 8x DVD±R DL should not be a problem for the majority of users, since this should make the drive a more accurate reader.

    The drive's compatibility with the RAM2 12x DVD-RAM media must be mentioned as a positive, although we have not tested this due to lack of such media in the European market.

    The drive performed very well in the CD-R writing tests, delivering almost excellent writing quality.

    The results are mixed when it comes to the writing quality with DVD recordable and rewritable media. On the bright side, we should mention the very fast 10x burning with DVD R DL discs, which also gave very good writing quality results in the corresponding tests. But that's not exactly the situation with the DVD±R discs. The drive burned the majority of the 16x certified discs we tested at a speed of 12x. This could be considered as reliable behavior, provided that the drive burns with higher quality at lower speed. However, the Z-CLV writing strategy used in 12X recording seems to cause many problems, with the majority of the discs producing high digital errors, which affected the playability of the discs in some cases. This does not mean that the discs were not readable, but they all tended to be outside the DVD specification limits. This has been reported by many other drives lately, but it was not expected to happen with a drive that burns at 12x.

    The drive managed to write at the maximum supported 18x speed with selected media, with good writing quality. Pioneer provides a complete listing of the media that are supported by the current v1.09 firmware here .

    To conclude, the drive left us with mixed impressions as an average drive, not really justifying its creator's claims. However, a firmware update can help this drive eliminate its flaws.
