CD Error Correction Tests

In the following tests we check the drive's behavior when it comes to reading scratched / defected discs. As usual, the test discs we use are the ABEX Test Discs series from ALMEDIO.

- ABEX TCD-721R

Errors total
Num: 890027
Errors (Loudness) dB(A)
Num: 50620
Avg: -72.6 dB(A)
Max: -14.3 dB(A)
Error Muting Samples
Num: 2938
Avg: 1.1 Samples
Max: 40 Samples
Skips Samples
Num: 7
Avg: 6.9 Samples
Max: 12 Samples
Total Test Result
69.1 points (of 100.0 maximum)

Pioneer DVR-A06 performed quite well in the specific test, although the ABEX TCD-721R disc is always very hard for the testing drives to be read accurately. The average error level is -72.6dB(A), and according to EAC author, such level is acceptable and does not lead to audible problems in the output signal.

However, the amount of errors muted is not very low and this weighted negatively to the total score. Overall, the score is 69.1 points out of 100, which is a good score compared to other DVD and CD recorders / readers.

- ABEX TCD-726

Errors total
Num: 221253
Errors (Loudness) dB(A)
Num: 10116
Avg: -72.8 dB(A)
Max: -15.2 dB(A)
Error Muting Samples
Num: 1223
Avg: 13.2 Samples
Max: 1095 Samples
Skips Samples
Num: 11
Avg: 38.2 Samples
Max: 168 Samples
Total Test Result
64.7 points (of 100.0 maximum)

The ABEX TCD-726 test disc contains defects and artificial fingerprints. The drive behaved adequately concerning the reported level of errors, although again some samples were muted. The score is better than in the previous test, reaching 64.7 points out of 100 possible.

Pioneer DVR-A06 gets a good score of 66.9 out of 100 at the error correction tests. The drive gave almost the same amount of errors with both scratched and defected discs, and the overall behavior with problematic media is obviously positive.

- CDSpeed Quality Test

Nero CDSpeed quality test applied on the ABEX TCD-721R also showed that the drive is able to read accurately defected discs. Although the reported C2 accuracy is low, the quality score is high.
