Pioneer BD-ROM BDC-202

3. CD Error Correction

In the following tests, we check the drive's behavior and error correction capabilities when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

- ABEX TCD-721R

 

Errors total
Num : 1854560
Errors (Loudness)
Num : 102618
Avg : -75.8 dB(A)
Max : -19.2 dB(A)
Error Muting
Num : 5556
Avg : 1.2 Samples
Max : 582 Samples
Skips
Num : 0
Avg : 0.0 Samples
Max : 0 Samples
Total Test Result
75.3 points (of 100.0 maximum)

An average score for the Pioneer drive. Although there were no skipped samples, the maximum Errors Loudness level is a little high, at -19.2 dB(A), and there were quite a few readings at that level so it is possible that some of these could eventually make their way to your speakers in the form of audible clicks.

- ABEX TCD-726R

Errors total
Num : 6830
Errors (Loudness)
Num : 3271
Avg : -87.5 dB(A)
Max : -53.4 dB(A)
Error Muting
Num : 34
Avg : 1.0 Samples
Max : 1 Samples
Skips
Num : 0
Avg : 0.0 Samples
Max : 0 Samples
Total Test Result
83.9 points (of 100.0 maximum)

Again, average performance. The drive should be better here. Some errors were reported but no skipped samples.

- CD-Check Audio Test Disc

The CD-Check Test Disc is another 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 more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.

The drive managed to correctly play the first three tracks. Problems occurred with the fourth and fifth tracks. Average behavior here. Overall, the drive exhibited mediocre performance with our defective test discs.
