TEAC DV-W512G

3. CD Error Correction Tests

TEAC DV-W512G Dual DVD±RW Recorder - Page 3

CD Error Correction Tests

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

- ABEX TCD-721R

Errors total
Num: 2032118
Errors (Loudness) dB(A)
Num: 52680
Avg: -69.2 dB(A)
Max: -10.5 dB(A)
Error Muting Samples
Num: 5433
Avg: 1.0 Samples
Max: 11 Samples
Skips Samples
Num: 0
Avg: 0 Samples
Max: 0 Samples
Total Test Result
76.3 points (out of 100.0 maximum)
C2 Accuracy
70.1 % (out of 100.0% maximum)

The DV-W512G performed poorly with the ABEX TCD-721R. The drive's highest peak reached -10.5 dB(A) while the total error count of 2032118 was high, and despite the total result score of 76.3 we would like to see the drive improve. Its quite interesting that the C2% accuracy seems very low with 70.1%. The previous 1S/2S series had much better C2% accuracy.

- ABEX TCD-726

 

The EAC analyzer reports error and didn't completed the task.

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

The files 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 tested device.

The drive passed the first three Check Levels of the test. The performance is quite good offering average sound reproduction and error correction. The fifth level includes an error size of 1.500mm, and the drive produced many audible clicks.

- Conclusion

The DV-W512G offers a rather poor CD error correction, we would like to see improvements with future firmware upgrade...
