Although summer is traditionally dead season in the IT industry, the launch of optical drives of the new DVD-Dual format started exactly in the summer months. The drivers come mostly as OEM solutions of other drive makers, but such drive has one vital advantages - they are usually cheaper than those coming from direct developers and manufacturers. Today we have a DVD-dual drive from TEAC. Unfortunately, this is not a long-awaited original solution but an OEM version of Pioneer's DVD-Dual drive. However, this fact doesn't make it less interesting as previous Pioneer's solutions made a good showing.
We got the drive in the OEM package, right at the time it started selling abroad. A bit later, when we were finishing the tests, TEAC sent us its retail version, so that we could see what's bundled with the drive and make sure that the drives are identical.
TEAC didn't redesigned the exterior, like in case of its DV-W50E drive. The front cover design is identical to the whole DVD recording drives line from Pioneer, with the air holes in front and space for a fan behind being their distinguishable features.
The drive has a standard suite of proprietary features first used in the Pioneer 105 and later enhanced in the 106 (here you can find in-depth information about them).
The drive sells with several software CDs, TEAC's 700 Mb CD-R, 4x DVD-R, IDE, analog audio cables, screws and a couple of booklets with useful information.
Here is the board it's assembled on.
As you can see, the drive is based on NEC's chip. The photo below shows the internal design.
The label on top informs us when and where it was made.
The installation caused no problems. A user is offered a standard procedure, like that of an ordinary CD-ROM drive. The drive needs no special drivers. You can do just with the NeroBurning Rom but you should use the latest versions as the older ones don't know it. I used v184.108.40.206.
Now let's use other utilities to get more information on the drive,
for example, Nero Infotool, which tells what formats and disc types the
As you can see from the screenshot, it's still impossible to turn the drive into RPC-1 (according to www.rpc1.com). However, you can use the DVD Region free program which provides the regional protection.
EAC (EAC Configuration Wizard) tells us whether it supports Audio CDs.
First I checked its compatibility with various non-brand-name media. No compatibility problems were detected, the drive perfectly reads and records the most of them. It should be noted that at the moment there are few drives able to detect and burn Princo's 4x DVD-R discs, and this model is one of them.
The discs were recorded without any problems, or errors at all speeds supported.
Here is the burn time for various media.
All DVDs recorded passed the control reading test on two reference DVD-ROM drives Toshiba SD-M1712 and Pioneer DVD-117LJ. The tests on the home DVD player BBK 939 revealed no problems with reading, the movies were played without artifacts.
Below are also results of reading the recorded discs for the Lite-On drive with the KProbe utility. The KProbe utility is a new test program developed for Widows OS which estimates a level of C1/C2 errors on a disc tested. The outcome may depend on whether the drive favors a given disc, but we can obtain some general data anyway.
TEAC DV-W50D, DVD-R, 2x burn speed (Fujifilm)
TEAC DV-W50D, DVD-R, 1x burn speed (Princo)
TEAC DV-W50D, DVD-RW, 2x burn speed (TDK)

NERO DVD Speed
Test DVD reading
Traditionally, the speed is limited at 2x in case of DVD-Video. It's good for watching movies as it eliminates noise, but such limitation is inconvenient for making backup copies.
Reading of recordable DVD
The drive flawlessly reads all types of recordable DVD media, as well as multiborder DVD discs.

CD burning time
Traditionally, we used two types of media - with cyanine and phthalocyanine coating. The number of the trade marks were lift up to 4, 2 of each type, to provide more information of how the drive treats discs of different trade marks. Below are the ATIP data of the discs tested.
The burning results will be partially represented in the graphical form.
The screenshot above looks the same for all trade marks. The burn speed
was the same for all trade marks and types of media. We also tested ability
of the drive to record cyanine discs at the minimal speed, - this mode
is usually used by audiophiles to get the highest quality sound.
To extend the picture, I added the results of the eproformance CD-RW 10x.
Time of CD-RW full formatting in UDF with InCD ver. 4.0.17

The drive reads and burns 80mm discs quite well.

The level of errors is not that high. Later we will publish the test results obtained with the professional equipment CDCATS SA3.
Here is the ATIP of the discs tested:

The detailed information on the tested parameters is given in the help file to the Nero CD Speed test program. If you don't want to download the utility, then here you can find the HTMl help file.
This test was developed by EAC and named DAE Quality (here you can find its description). In short, it measures quality of audio data extraction and of C2 error processing using a special test disc. But in this case we couldn't measure C2 processing quality, and below are only general data on quality of audio track extraction.
The drive copied the contents of the 780MB disc without errors.
The copy time was
|CD-RW drive||Tray||CD-Seek||CD, total||DVD-Seek||DVD, total|
The drive works pretty quietly except those cases when it works with CDs which are not properly balanced and when it works at the maximum speed.
|CD-RW drive||T inside PC case, C||T of the upper surface, C||T of the lower surface, C|
The drive doesn't get too hot even when used a lot. But be careful when placing other devices close to it as they can burn.
The drive vibrated a little when worked with such discs but it finished reading them at a high speed and without errors.
This drive can be recommended even for very demanding users. No grave flaws
or problems were noticed. The impression is generally positive, though
it burns CD-R and CD-RW too slowly, and I hope that its next versions will
have it lifted it up to match the up-to-date level. Since the OEM manufacturers
is Pioneer, a leader on the DVD-R market, we can see that it finally accepted
the DVD+RW format.
