Pioneer DVR-115D


1. The drive

Pioneer's DVR-115D is a high speed DVD ReWriter supporting all DVD media types currently available. The DVR-115D is capable of burning DVD±R media at 20X, DVD±R DL media at 10X, DVD+RW at 8X and DVD-RW at 6X. However, writing of DVD-RAM discs is not supported. CD-R media can be burned at 40X and CD-RW at 32X.

Key Features

The new writers retain Pioneer's Disc-Resonance Stabiliser technology. This controls the airflow generated by disc rotation in order to minimise disc warping, which can occur when media rotates at high speed. As well as 'Buffer Under Run' protection technology for DVD and CD, writing performance is further advanced by technologies including:

A Multi-Effect Liquid Crystal Tilt Compensator operates at high speed even on Dual Layer/Double Layer media types to ensure precise writing to the disc by automatically compensating for discs that are warped or of uneven thickness.

The Ultra Dynamic Resonance Absorber reduces the instability and vibrations caused by imbalanced or damaged media, maintaining the integrity of the recording and playback performance.

Performance Adjusting Firmware: this 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 keeping background noise to a minimum:


Pioneer DVR-115D is also available in under the code-names DVR-A15J (Japan) and DVR-A15XL. These models retail with more "advanced" options, including Pioneer's "PureRead" and "PowerRead" functions. Unfortunately, our DVR-115D sample we have here in our labs does not support these two advanced functions, but they both deserve the mention.

PowerRead: There is a difference between how AV and PC handle discs that are difficult to read. In a standard PC environment, DVD-Video is treated as 1 type of data, therefore, if a section is deemed unreadable, playback will stop. With PowerRead, the user-experience is similar to the AV side, making it possible to play the remainder of the disc. Note that with PowerRead, unreadable contents remain unreadable. PowerRead skips to the next readable address.

The PureRead function compensates the noise introduced when a scratched or dusty audio CD is reproduced. The idea behind PureRead is to try and correct damaged sectors which are read from the Audio-CD. The feature re-reads damaged sectors to see if it can recover them (I.E. when ripping an Audio-CD). When these damaged sectors are read in a normal scenario, the sector may well be read without any serious error, but sometimes pops or crackles can be heard in the final ripped file. When a sector that is difficult to read is detected, the laser tries to re-read the damaged sector. Not just re-reading the sector, but the drive will actually adjust its read parameters (I.E. higher or lower laser power and the angle of the laser beam are adjusted) to try and get the best-possible read-back from that damaged sector. An algorithm calculates the "best" or "average" result it achieves, and that information (I.E. the best-possible result) is then used as part of the final ripped MP3 file. Re-reading of damaged sectors can be up to a maximum of 40 times.

PureRead offers are 3 reading modes (that can be set by Pioneer's "QuietDrive utility"):

    This drive is built on the NEC MC-10041 Chipset.

    Click for High Resolution Image

    Installation

    The drive was connected via the typical ATA interface and was recognized as "PIONEER DVD-RW DVR-115D ".


    2. CD/DVD reading tests

    For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of data and audio CD-R/RW/ROM. The drive can read CD media at a maximum speed of 40X.

    For each CDSpeed graph, you can click on the image to see the complete screenshot, including full measurements.

    -CD-ROM

    - US RW

    The following CD Speed graph shows the reading performance with US-RW media. Reading reached a maximum of 32x, as per the specifications.


    - AudioCD

    In the CD Speed Advanced DAE quality test, the drive's average speed was 27.62X with a quality score of 100.0

    A typical DAE task with an 80min non-protected Audio CD produced 23.5X average ripping speed.

    - 90/99 mins Audio disc

    90min audio

     

    99min Audio

    The drive failed to read both the 90min and 99min audio CDs.

    DVD Format

    Now let's take 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.

    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.

    Maximum 17,855KB/s(12,9x)

    - Summary of reading tests

    A very good performance from the Pioneer drive, attaining the reading speeds outlined in the specifications with all CD and DVD media.


    3. CD error correction

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

    An average score for the Pioneer drive. Although there were no skipped samples, the maximum Errors Loudness level is a little high, at -19.2 dB(A), and there were quite a few readings at that level so it is possible that some of these could eventually make their way to your speakers in the form of audible clicks.

    Bad performance. The drive's performance should be better here.

    - 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.

    The drive managed to correctly play the first three tracks. Problems occurred with the fourth and fifth tracks. Average behavior here. Overall, the drive exhibited mediocre performance with our defective test discs.


    4. DVD error correction

    In the following tests, we examine the DVD reading capabilities of the drive (error correction) 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.

    Flawless reading, without any problems and without dropping speed.

    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.

     

     

    - 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.

     

    Here too, the drive continues its good reading performance.

    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.

     

    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.

    Approaching the defect, the drive slowed down for better performance.

    .

    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.

     

    The defects on both the ABEX TDV-545 & ABEX TDV-541 were overcome by the drive, some times slowing it down.


    5. CD-R writing tests - Ritek 32x

    For this test (and for all ensuing tests with CD-R media), the 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.

    DaTARIUS Scans -

    The good overall pisture of the disc was ruined by POF reported at the 44mm radius.

    We should note here that POFs occur when the decoder is unable to correct all the data within an ECC block after attempting one pass of PI Row correction and PO column correction. The wording "one pass" is important because a commercial decoder is usually designed to make several passes or attempts during error correction. There is a possibility that bad bytes may be corrected in one of the subsequent passes. The decoders of DVD testers such the DaTARIUS system, use one pass during error correction. As a result, in some cases where POFs are reported by the tester, these can be corrected by commercial players and drives during reading due to multiple passes.

    - Booktype Settings

    The drive does not support the booktype feature.

    - DVD Overburning

     

    As we can see, the drive supports a bit of overburning of DVD recordable media, according to CDSpeed.


    33. Final thoughts

    The DVR-115D all round DVD ReWriter generally performed adequately, meaning that it would do the job in your daily burning/reading tasks. It is capable of burning DVD media at high speeds, thus staying within the range of the DVD burners' competition.

    Summarizing the test results, we should mention that the CD error correction mechanisms of the drive proved to be mediocre, generating high levels of noise, some times audible. DVD error correction was good, successfully reading all of our defective discs. However, during error correction, the speed was some times decreased automatically, in order to increase correction efficiency.

    As far as reading and writing speeds are concerned, the drive satisfied us, meeting its specifications. We were able to burn MCC 03RG20 , TYG03 , MCC 004 and YUDEN000T03 discs at 20X and some other at 18X. Also, all of our high speed DL discs were burned at 10X.

    Moving on to the writing quality tests, we have to say that the Pioneer drive did not make quite a good impression. Only a few of the DVD+R/-R discs were burned flawlessly and the rest of them had many uncorrectable errors. Keep in mind, though, that the discs' readability was normal, with all of them being successfully read by the drive itself. On the other hans, CD-R/RW discs were burned accurately.

    The support for overburning with DVD recordables is a plus while we would welcome any Pioneer's decision to offer booktype setting sometime in the future.

    The DVR-115D can be found at the stores for about $30-$40.
