The drive uses 2MB buffer memory. RAW DAO 96 writing (CD) is supported, while Mount Rainier is not.

The TEAC DV-W58G-A uses the RPC II region control, allowing a user to change the drive's region at most 5 times. For our tests, we set the region code to 2 (Europe).

- Retail package

The retail package includes the warranty, a multi language printed user manual, mounting screws, IDE and analog audio cables.

Packaged software includes Nero Burning Rom software along with a blank TEAC DVD+RW 4x media.

- The drive

On the rear panel there are the analogue and digital audio outputs (SPDIF), the IDE connector and the power input.

Removing the screws and opening the drive's cover voids the drive's warranty. For reference reasons, we post the following pictures.

- Installation

The TEAC drive was connected to our test PC and was identified as "TEAC DV-W58G-A" under WinXP. All tests were performed with firmware v.U4S2.

The following pages include test results for TEAC drive in comparison with two other dual 8x DVD burners, Nec ND-2500A and Pioneer DVR-107D.

2. Data CD Reading Tests

The performance of DV-W58G-A is good in all test although the drive is not the best available on the market.

3. CD Error Correction Tests

TEAC DV-W58G-A - Page 3

Error Correction Tests

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

The 726 Abex test disc is easier for most drives to read. Teac drive just ignored the defected area on the disc.

- 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 reading music abilities and reproduce it completely. Five tracks on the disc contain a progressively difficult sequence. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks 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 drive.

Error Level	1	2	3	4	5
TEAC DV-W58G-A	5/5	5/5	5/5	0/5	0/5

The TEAC drive played only the first three levels of the CD-Check Audio test disc without noticeable clicks. The fourth and fifth levels produced continuous audible clicks. The performance is acceptable but we expected to be better.

4. DVD reading tests

TEAC DV-W58G - Page 4

DVD reading tests

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

- Dual Layer PTP DVD-ROM (Click for CDSpeed results)

- Dual Layer 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 on 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 inwards towards the inner tracks of the disc.

- DVD Ripping Tests

We measured the DVD-Video ripping speed for the TEAC DV-W58G-A using the latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed DVD-Video.

The graph above shows that the TEAC drive is very fast in this procedure. The average speed of 6.8x is very good.

- DVD Recordable / Rewritable reading Tests

The chart below shows the Nero CDSpeed average reading speed results with the following media:

In the previous tests Teac performed exceptionally with high speed, the fastest seek times and high ripping speed.

5. DVD Error Correction Tests

TEAC DV-W58G-A- Page 5

DVD Error Correction Tests

In the following tests we examined the DVD reading capabilities of the TEAC 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 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.

ABEX TDR-825

This is also a single sided, single layer DVD-ROM with 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 the surface but instead defective areas ranging in dimensions from 0.5 to 1.1 mm. There are also artificial fingerprints with height 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.

ABEX TDR-845

This disc is a single sided, dual layer DVD-ROM disc with capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first includes both defective areas and fingerprints. The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints have height sized from 65 to 75 microns (micrometers).

In the four previous tests Teac revealed that it has very good DVD error correction ability. All the defected discs were read without malfunctions and readable 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 on 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 sized from 0.4 to 3.0 mm.

The specified disc was read successfully despite the fact that there was a slight glitch just after the switch over to the second layer, but the drive recovered quickly.

ABEX TDV-545

The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer Video/S-2 disc with a capacity of 8.5GB. The TDV-545 includes artificial black dots on the disc's surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometers high fingerprints.

This is also good behavior for a drive of its kind.

6. Protected Disc Tests

TEAC DV-W58G-A - Page 6

Protected Disc Tests

- Reading Tests

To create an image of the various protected titles onto a hard disk, we used Alcohol 120% v1.4.8.1222 and the appropriate settings, depending on the protection type of the inserted discs. Below the capabilities of the TEAC drive are summarized, according to CloneCD software. The summary below shows that the drive supports CD+G writing under RAW DAO:

The game titles we used to test the reading speed for each protection scheme are presented in the table below:

Game Title	Protection Scheme
PSX "NBA Jam Extreme"	Lybcrypt
Serious Sam The Second Encounter v1.07	SafeDisc v.2.60.052
VRally II	SecuROM v.2

PSX Pressed Media

SafeDisc v.2

SecuROM v.2

TEAC had a high ripping speed in all the previous tests. It was the fastest with SafeDisc and SecuRom protections while it was good with PSX media.

- Writing Tests

TEAC supports DAO-RAW writing mode. For checking the drive's EFM correction status, we used 3 different game titles with different SafeDisc versions and with the latest software patches installed. After making the image files of the various titles to the hard disk, we burned them (maximum speed) with Alcohol 120%. 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 work (game installed / played normally), or not.

Teac managed to make working backups of all the SafeDisc games we tried, even the latest. The fact that the backup was not playable without the contribution of the software, EFM off, didn't affect the good image of the drive.

7. DAE Tests

TEAC DV-W58G-A - Page 7

DAE Tests

- Pressed and CDR AudioCD results

According to the manufacturer, the TEAC DV-W58G-A drive supports 40x CAV for DAE.

The specifications of the drive were confirmed by CDSpeed.

We ripped the contents of the same audio disc to our hard disk, using the CDDAE software. The average ripping speed (burst mode) of 28.5x, was the fastest among the two other drives.

With the CDR audio disc, the performance was almost the same as with the original, quite faster that the other two drives.

- Advanced DAE Quality

The average reading speed of the TEAC drive according to Nero's CD Speed Advanced DAE test, is 28.26x. The quality score of the drive is 100, while no data or sync errors were reported during the test. Also according to the software the drive can safely be used for on the fly copying at up to 16x reading speeds , with an exception at 6x. In addition the drive supports Leadin / Leadout reading and Subchannel Data information.

- Support of 90/99mins AudioCDs

TEAC managed successfully to rip the contents of our 90/99min test discs.

- Reading/Ripping Protected AudioCDs

For the test procedure we used two audio discs with different audio protection schemes. We tested both recognition and ripping to the hard disk. The software used was Exact Audio Copy.

* Pressed Audio disc protected by Sony Key2Audio (Celine Dion - New Day Has Come)

* Pressed Audio disc protected by Cactus Data Shield 200 (Natalie Imbruglia - White Lilies Island)

8. CD Recording Tests

TEAC DV-W58G-A - Page 8

CD Recording Tests

- CD-R Writing Tests

The TEAC DV-W58G-A supports a maximum CD-R writing speed of 40x. To confirm this we used a blank 80min CD-R disc from TY and NeroCDSpeed to emulate the writing process.

After the end of the test, CDSpeed reported an average speed of 31.45x. The ending speed at 41.56x confirmed the drives specifications.

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc. The difference between the drives was expected, due to the different maximum supported speed of each.

Bellow two graphs are presented, where you can compare the writing times with different media brands, while in the second one you can compare the times in all the supported speeds for Teac Drive.

- CD-RW Writing Tests

TEAC DV-W58G-A supports 24x(Z-CLV) for US-RW media. To test the writing speed and method used for the TEAC with the -RW format, we used CDSpeed writing simulation test with a blank 24x US-RW media from Mitsubishi Chemicals.

Once again our test confirmed the drive's specifications.

Below we provide a comparison of the three drives where we used Nero Burning Rom software to burn a 651MB data compilation onto 24x US-RW media from Mitsubishi Chemicals.

The difference between Teac and Pioneer is logical due to the different supported speed for this type of recording.

- Packet Writing Tests

For the packet writing test we used the InCD packet writing software from Nero and a Mitsubishi Chemicals 24x US-RW media. The tested file is a 403 MB file (412.822 KB) and we used the drag and drop method with Windows Explorer to write the file from our hard disk onto RW media.

Writing Quality Tests - 3T Jitter Tests

As we mention before, TEAC DV-W58G-A supports 40x maximum writing speed. We burned five Taiyo Yuden media, in order to test the writing quality at all the available writing speeds.

- 3T Pit results

As we can see from the graph above, the higher the speed the better the quality. Recording at 8x and 16x is not very good. This is also confirmed in the following graph, with the average Pit jitter values.

- 3T Land results

From the Land jitter values we experienced, all speeds are in acceptable levels.

Recording Speed	Average 3T Pit Jitter (ns)	Average 3T Land Jitter (ns)	> 35ns	Max 3T jitter values (ns)
8X	41.68	35.85	Yes	44 Pit, 37 Land
16X	40.12	32.63	Yes	45 Pit, 34 Land
24X	34.90	31.41	Yes	41 Pit, 34 Land
32X	35.00	35.00	Yes	40 Pit, 40 Land
40X	34.88	34.56	Yes	40 Pit, 42 Land

Teac had an average performance in this tests. We estimate that the jitter levels should be lower, especially for the maximum values.

10. 3T Jitter Tests - Page 2

TEAC DV-W58G-A - Page 9

Writing Quality Tests - 3T Jitter Tests

Here we examine the writing quality of the drive at the maximum allowed speed, 40x, using this time media from different brands.

- 3T Pit results

All media reported good writing quality, but we still expected a better one. Intenso media had an extremely high level at the end of the recording area.

The above graph shows the average Pit values for each recorded disc.

- 3T Land results

Mam and Intenso didn't prove to be the best combination with this drive. All the other media had acceptable jitter levels.

Media Brand	Average 3T Pit Jitter (ns)	Average 3T Land Jitter (ns)	> 35ns	Max 3T jitter values (ns)
PHILIPS 52X	35.12	37.93	Yes	40 Pit, 40 Land
PLATINUM 52X	34.37	37.46	Yes	39 Pit, 40 Land
INTENSO 52X	37.66	44.24	Yes	54 Pit, 54 Land
SAMSUNG 52X	36.90	38.80	No	39 Pit, 41 Land
CMC Magnetics 48X	32.37	33.66	Yes	40 Pit, 38 Land
MAM 52X	33.76	39.20	Yes	39 Pit, 45 Land

Once again the maximum values for each disc were high. We expect a new firmware upgrade to improve the recording quality.

11. C1 / C2 Error Measurements

TEAC DV-W58G-A - Page 11

13. KProbe PI/PO quality tests

TEAC DV-W58G-A - Page 12

KProbe PI/PO quality results

The following screenshots show the PI/PO scans for various DVD-/+R and DVD-/+RW media, recorded with TEAC DV-W58G-A at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.26, the ECC was set to 8 and the reader was LiteOn LDW-811s. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Hence, we cannot safely come up with conclusive results, although we do make a comparison of the drive behavior when using various DVD recordable/rewritable media.

The recordable discs we use, came from Verbatim, Taiyo Yuden, CMC, MAM, Maxell , MC and Ritek. Further details about each disc type are presented at the bottom of this page.

Conclusion

Pros

Cons

8x DVD±R writing

4x DVD±RW writing

40/24/40 CD-RW

DAE speed

Good CD/DVD Error correction

CD-R Overburning up to 94min

Fast DVD ripping

Working backups with SafeDisc v3.10 protection

Support of 90/99min discs

Support protected AudioCDs

Increased PI/PO values with many DVD media

Low CD Writing quality with specific media

The drive had a good performance in the CD reading tests, with high speed and good seek times. However we would like the full seek time mode to be lower. For the same format the error correction is rather good. The performance with the Abex test disc was very good. However the CD-Check Audio Test Disc seemed to be a little difficult for the Teac drive where only the three first tracks were played without problems.

In the DVD tests the Teac drive had, once again, good reading speed and very good seek times for all modes. The DVD ripping speed was the higher and the DVD error correction, with both single and dual layer test discs, was also very good.

The DV-W58G-A drive managed to make working backups of all the protected games we tried, while the ripping speed was high for all the protections we tested.

In the audio part the drive had a high DAE speed, while supports Leadin and Leadout, CD text and Subchannel data. The drive also supports 90min and 99min discs. Here we must also refer the ability of the Teac drive regarding the protected AudioCDs. Both of our test pressed media were playbacked and ripped successfully.

The maximum allowed CD writing speed is 40x, which is high. In the writing quality part there were no C2 errors reported and the C1 levels were low in all cases, except with Mam and Intenso media. From the jitter measurements we estimate that the maximum values were increased while the average levels were acceptable. Also we would avoid writing at 8x and 16x. Maybe a firmware upgrade will improve this.

For the DVD writing part, the drive managed to burn both formats at 8x, -R and +R, and at 4x the RW formats. As far as it concerns the writing quality there were some cases that it was very good, but at most the PI/PO levels were extremely increased. Here too a firmware upgrade would be highly anticipated.
