3. CD Error Correction

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


Errors total Num: 2387905
Errors (Loudness) dB(A) Num: 116353 Avg: -75.5 dB(A) Max:-35.8 dB(A)
Error Muting Samples Num: 7190 Avg: 1.2 Samples Max: 582 Samples
Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
Total Test Result 75.0 points (out of 100.0 maximum)

The total error count is a little above average but the the maximum error loudness is very low and no samples were skipped. The Total Test Result score of 75.0 is quite good.

- ABEX TCD-726

LG_GBW-H10N-ABEX 726 Test disc

Errors total Num: 157605
Errors (Loudness) dB(A) Num: 18914 Avg: -82.8 dB(A) Max: -46.1 dB(A)
Error Muting Samples Num: 651 Avg: 1.0 Samples Max: 3 Samples
Skips Samples Num: 0 Avg: 0 Samples Max: 0 Samples
Total Test Result 79.2 points (out of 100.0 maximum)
C2 Accuracy 100.0 %

It is unusual to see a drive register so many errors with this test disc. The Total Test Result score of 79.2 is a little disappointing.

- 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 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.

Error Level

With this test disc, the drive managed only the first 2 of 5 tracks which is a little below average.

- Summary

Overall, the drive is not very good with faulty CD media. Apart from the TCD 721-R disc, its performance was below average.
