The drive uses 2MB buffer memory. RAW DAO 96 writing (CD) is supported,
whereas Mount Rainier is not.
The TEAC DV-W58G 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
and an analog audio cable.
Packaged software includes NeroBurning Rom software
along with a blank TEAC DVD-R 4x disc.
- The drive
The drive's front panel is bone color, and on the loading
tray are the CD-RW logo ,
the +RW and -RW logos and the TEAC logo (colored blue). Also on the front panel
are the eject button, the activity led indicator, volume control, emergency
hole and a headphone jack.
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. Notice that this time,
unlike to the previous DV-W50D model (4/4 DVD±R, Pioneer reference design),
TEAC chose the MediaTEK chipset for this model.
- Installation
The TEAC drive was connected to our test PC and was identified
as "TEAC DV-W58G" under
WinXP. All tests were done with firmware v.H4S2
The following pages include test results for TEAC drive in comparison
with two other dual DVD burners, the Sony DRU-530A and the Pacific Digital
8xDVD.
2. Data CD Reading Tests
TEAC DV-W58G - Page 2
Data CD Reading Tests
- Pressed CD results (Click for
CDSpeed results)
The TEAC DV-W58G supports 40x maximum reading speed with CD media and proved
the fastest among the three drives, although there was very little between them,
with a maximum final speed of 41.84x. The reading strategy of the TEAC drive
is CAV.
As the seek times tests show, again there is not a lot between the drives
but the TEAC drive was the slowest with all three seek times. However, the seek
times are fast enough and the results are quite acceptable. The drive finished
the full seek with 191ms, while 92ms was needed for the random seek.
- CD-R Media results (Click for
CDSpeed results)
With CD-R media, the TEAC DV-W58G managed to reach a maximum end speed of
41.74x, a result that is again marginally higher than the other two drives used
in this comparison. The reported average speed was 31.44x
On this test we measured the seek times of the TEAC drive with CD-R media.
The seek times for this test are slightly up in comparison with the previous
pressed disc test. The full seek finished after 210ms for both TEAC and Pacific
Digital while the Sony was fastest at 151ms.
- ReWritable Media (Click for
CDSpeed results)
To check the reading performance for the TEAC DV-W58G with HS-RW media, we
used NeroCDSpeed and a HSRW rewritable disc from Mitsubishi Chemicals. After
the end of the test, NeroCDSpeed reports that the drive read the disc under
CAV mode with an average speed of 25.23x. The drive was the slowest among the
three drives, with a final reading speed of 33.45x compared to SONY's 40.69x,
however the TEAC has a maximum reading speed of 32x with CD-RW media.

TEAC`s DV-W58G results are quite good with the Abex 721R test disc, which is
usually a hard disc to read accurately with most drives. There are relatively
few totla errors, maximum loudness is also low at -36.0 dB(A) and there were
no skipped samples. The final score of 76.9 out of 100 is very
good.

The 726 Abex test disc is easier for reading by most drives. After finishing
this test, the TEAC drive received a total score of 100.0. No errors were reported.
- 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.

DVD reading tests
- Single Layer DVD-ROM (Click
for CDSpeed results)
After performing the Single Layer DVD-Rom reading test, Nero CDSpeed reports
that the TEAC drive is the fastest among the three drives. The final reading
speed for the TEAC is 12.45x and the reading strategy is CAV. As with the same
test with CD media, there is very little between the drives.
The seek times for the TEAC DV-W58G are very good. It had the fastest seek
times with a reported full seek time of 159ms and average seek time of 84ms.
- Dual Layer PTP DVD-ROM (Click for
CDSpeed results)
The two layers of a PTP DVD-ROM disc are read sequentially, with the drive
starting the read process from the inner tracks on the disc, where lies the
beginning of each layer and progressing outwards towards to the outer tracks
for each layer.
After the end of the Dual Layer PTP DVD-ROM test, we can see that again there
is very little between the drives and while the TEAC drive was not the fastest,
the speeds are quite satisfactory. The reported end speed for this test is 8.44x,
which is slightly slower than 8.60x for the Sony drive which proved overall,
to be the fastest drive among the three.
Just as with Single Layer DVD-ROM media, the seek times for TEAC are fast
and was the fastest with all three seeks among the three drives. The drive needed
86ms for random seek and 164ms for full seek.
- 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.
The Dual layer OTP disc was not a problem for the TEAC DV-W58G drive. The
average reading speed was 6.18x, while the end speed reached at the end of the
first layer was 8.32x. There are some annoying glitches where both the disc's
velocity and hence speed, took some tumbles during reading of the second layer.
It remains to be seen if this proves a problem during our quality tests later
on this review.
- DVD Ripping Tests
We measured the DVD-Video ripping speed for the TEAC DV-W58G 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 was not the fastest among the three
drives for DVD ripping, but the ripping speed is reasonable.
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed average reading speed results with
the following media:
The drive is specified as having a maximum reading speed of 6x with DVD±R/RW
media, compared to the SONY DRU-530A's 8x, hence it's times are going to be
below those of the SONY drive's, which happened to be the fastest in this test.
NeroCDSpeed reports that the average reading speeds with the TEAC drive for
all four media is a little above the 4.6x mark, while the reading strategy is
CAV with all formats.
5. DVD Error Correction Tests
TEAC

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.
The resultant output is smooth and relatively clean. The TEAC drive did note
return any read errors, reading was accurate and the final speed was 12x.
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 and instead
defective areas ranging in dimensions from 0.5 to 1.1 mm. There
are also fingerprints with height
between
65 and
75 micrometers.
Here again we have a very smooth graph with no errors, and the drive passes
over both areas containing scratches and fingerprints, without any problems.
the TEAC drive proves so far to be a very good DVD reader. The test was finished
succesfully and the reading speed was 12x CAV.
- 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.
The TEAC DV-W58G once again performed extremely well and managed to finish
this defective surface test without posting any errors. Each layer of the disc
reached a maximum reading speed of over 8x CAV.
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 (micrometres).
So far, the drive has performed brilliantly and seems to be an
excellent DVD reader with defective media.
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 average reading speed was 6.33x while the speed at the end of the first
layer reached 8.46x. Also, NeroCDSpeed reports low seek times for the disc.
There is a slight glitch just after the switch over to the second layer, but
the drive seems to recover 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 micrometre high fingerprints.
This test disc also proved not to be a problem. The reading strategy
was CAV, while the maximum speed reached at the end of the first layer was 8.40x.
6. Protected Disc Tests
TEAC
DV-W58G -
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 are summarized the capabilities of the TEAC
drive, according to CloneCD software. The summary below shows that the drive
supports writing of CD+G under RAW DAO:
The game titles we used to test the reading speed for each protection scheme
are given 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 was fast ripping all of the pressed game discs we tested. According to
the graphs above, the TEAC DV-W58G was consistently fast with all three protection
schemes, something which is rare for a drive. It was the fastest reading the
safedisc protected disc, and not far the fastest drive (Pioneer DVR-107D) for
the other two protection schemes.
- Writing Tests
TEAC supports the 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 working (game installed / played normally), or not.

DAE Tests
- Pressed and CDR AudioCD results
According to the specifications, the TEAC DV-W58G drive supports 40x CAV
for DAE.
Nero
CDSpeed confirms TEAC's specifications. The maximum DAE speed reached was 40.87x.
The disc reading was under CAV mode with an average speed of 30.93x.
We ripped the contents of the same audio disc to our hard disk, using the
CDDAE software. The average ripping speed (burst mode) of 35.2x, was the fastest
among the three drives and is one of the fastest speeds with this test (e.g.
the LiteOn LDW-811s has reached 39.9x).
With the CDR audio disc, the performance was not as good as
with the original, but it was still 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 28.12x. The quality score of the drive is 100,
while no data or sync errors were reported during the test. The software also
reports that the drive can safely be used for copying on the fly at reading
speeds up to 16x. In addition the drive supports reading of Leadin, Leadout
and Subchannel Data information.
- Support of 90/99mins AudioCDs
TEAC managed to rip the contents of our 90/99min test discs
successfully.
- Reading/Ripping Protected AudioCDs
For the test procedure we used two audio discs with different
audio protection schemes. We tested for both recognition and
ripping to the hard disk. The software used was Exact Audio Copy.

CD Recording Tests
- CD-R Writing Tests
The
TEAC DV-W58G supports a maximum writing speed of 40x for the CD-R family. To
test the writing speed and writing method of the drive we used a blank 80min
CD-R disc from TY and NeroCDSpeed to emulate the writing process.
After the end of the test, software reports that the disc
was written under CAV mode with average writing speed 31.58x.
- Recording Times
We created an 80min data compilation with Nero Burning Rom and recorded it
on a 700MB disc. All three drives support a maximum writing speed of 40x, therefore
the writing time for all three drives is about the same. As we can see from
the above graph the fastest writing speed comes from the Pacific Digital drive
which took 3:08min, while the TEAC drive finished the writing process in 3:10min.
On the above graph we have summarized the writing speeds from
the three drives for all possible recording speeds. Overall, the Pacific Digital
drive is the faster recorder among the three but the TEAC is very close behind,
there not being much betweeen them.
We used various manufacturers media to test the writing speed
and media compatibility of the TEAC drive. All discs we tested were written
at 40x and most had times below 200 seconds except for Mam SG Ultra, manufactured
by Mitsui, (Code:97m27s58f) that was written at 24x, although it is certified
for writing at 48x.
- CD-RW Writing Tests
TEAC
DV-W58G supports 4x(CLV) for low speed CD-RW, 10x(CLV) for High speed CD-RW
and 24x(Partial CAV) for Ultra speed CD-RW. To test the writing speed and method
for the TEAC with the -RW format we used CDSpeed writing simulation test with
blank 24x US-RW media from Mitsubishi Chemicals.
The test confirmed the drives specifications for 24x rewriting.
The burning procedure started at 18.59x and finished at 24.35x
having an average speed of 23.46x
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 graph shows that all drives took almost exactly the same time
to complete the test, while the TEAC drive was about 6 to 7 seconds slower with
Quick Erase process.
- 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
The TEAC DV-W58G supports 40x maximum writing speed. We burned five TY discs
to test the quality at all available writing speeds and five media from other
manufactures to test the writing quality with various media.On the following
graphs we summarize the 3T Pit & Land Jitter of the various written discs.
- 3T Pit results
The Pit Jitter results for the TEAC drive are higher than we had expected.
Apart from CMC, Ritek and MAM media, the rest returned higher pit values than
the 35ns Red Book limit. Notice on the above graph that the TY disc returned
the highest results. Also note that the MAM disc was written at 24x although
it is certified for 48x maximum writing speed. In addition both MAM and Ritek
discs, gave back Time Outs (non readable areas) during the measurements.
The above graph shows the average Pit values for each recorded
disc. Notice that even the average Pit for the TY disc, exceed the 35ns Red
Book limit.
- 3T Land results
The Land Jitter values for the same discs written with the TEAC DV-W58G are
at around the same levels in comparison with the Pit values. CMC is the only
media brand that remained within limits in both land and pit jitter.
The following average graph confirms the low levels.

The above table shows that apart from CMC media, all other media returned final
values over the 35ns Red Book limit, although having a closer look at the table
we can also see that only TY and TDK media returned average Pit and Land values
higher than the 35ns Red Book limit.

DVD Recording Tests
- Writing Performance
TEAC DV-W58G supports DVD-R/RW and DVD+R/RW writing. The maximum
supported speed is 8x for DVD+R and 4x for DVD-R. With RW format, TEAC supports
4x for DVD+RW and 2x for DVD-RW.
4x DVD-R
To
test the performance of the TEAC DV-W58G with DVD-R writing process, we used
NeroCDSpeed to emulate the process and a TY DVD-R, certified at 4x writing.
After the end of the test, the software reports that the drive wrote the disc
under CLV, with an average speed of 3.96x, while the start speed was 3.95x and
the end speed 4.11x.
8x DVD+R
With
plus format, the TEAC supports 8x writing speed and uses the Z-CLV writing strategy.
For this test we used Nero`s CDSpeed "create disc" function. The software
reports that the write process started at 6.13x and finished with an end speed
of 8.10x. As we can see from the picture below the drive increased the speed
after the 1.3GB address mark on the disc.
4x DVD+RW
With
DVD+RW format, drive supports 4x CLV writing method. After the end of the test,
manufacturers specifications were confirmed with start and end speed at around
4x.
2x DVD-RW
With
DVD-RW format, TEAC supports 2x writing speed. After the end of the test, the
software reports that the disc was written under CLV mode with average writing
speed 1.99x.
- Burning Tests
The following graphs show the maximum writing speed for all available DVD
formats . For comparison, we also include the writing times of the Sony DRU-530A
and Pacific Digital 8xDVD drives.
There is no major difference between the drives except for DVD+R media where
the Sony was slightly slower. Despite the closeness of the comparative times,
the TEAC drive wa the fastest among the three.
The following screenshot was taken from Nero, after successful
burnings. The
recording project is the same DVD-Video compilation for all tests.

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 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.

reading speed
|
In the CD reading tests, the drive returned very good results,
with low seek times and accurate reading even at the maximum speed of 40x.
The reading
accuracy of the drive was also very
good, which
means
that
it can safely be used for playback and ripping of old and ligtly scratched
media.
With DVD media, the drive had low seek times and accurate reading under the
supported CAV mode. In the DVD ripping process with DVD Decrypter, Teac had
the fastest speed compared to the other two drives used in the comparison. In
addition, the error correction tests with defective DVD media posted near perfect
results, where the drive managed to pass all the tests without read errors.
The drive also proved to be a good recorder for protected
games.
For our tests we used games with the latest protection schemes, like Safedisc
3.10 where the drive managed to create a valid
backup, with Amplify Weak Sectors (Clone CD) enabled.
The DAE speed of the drive was high, although it does
not support Key2Audio protected discs.
In the recording tests, the drive confirmed the supported 40x writing
for CD-R format. The writing strategy is CAV and all media we tested was
written at
the maximum
available speed. The only exception was MAM media, which was recorded at
24x.
Despite the writing speed compatibility, written discs reported increased
Pit and Land jitter values with some discs such as Taiyo Yuden, TDK and Creation.
In addition, the C1/C2 error measurements revealed high
C1 levels, while in
two
others,
C2 errors
were reported.
For DVD+R media the drive used the 6-8x Z-CLV writing strategy, making it
faster than other DVD burners, offering a three-step Z-CLV implementation (4x-6x-8x).
This means
that the writing time is about 8:20 min for DVD+R. On the other hand, DVD-R
was burnt in 14:30 minutes. The quality of the DVD written media was checked
with KProbe which reported high PIPO values with some brands. However, with
Taiyo Yuden and Mitsubishi Chemicals DVD+R media, the drive made quality recordings.
Weighing up all the pros and cons, and despite the fact that overall performance
could be better, the reasonable
price
of the Teac DV-W58G at around $130 on the market, could be a good enough incentive
for buying it.
