CD Error Correction Tests

Now, it's time to see how the Action 16 performs while reading scratched / defective discs. The test discs we used are the ABEX series from ALMEDIO.

- ABEX TCD-721R

Errors total
Num : 935215
Errors (Loudness) dB(A)
Num: 51269
Avg:-74.1 dB(A)
Max: -23.1 dB(A)
Error Muting Samples
Num: 3058
Avg: 1.0 Samples
Max: 11 Samples
Skips Samples
Num: 0
Avg: 0.0 Samples
Max: 0 Samples
Total Test Result
76.8 points (of 100.0 maximum)
C2 Accuracy 97.6 %

The drive managed to achieve a total test result of 76.8 out of 100, which is a fairly good result. The -23.1dB(A) maximum loudness level is also good and combined with the low total error count of 935215 and zero skipped samples, results in an overall good performance when reading this test disc.

- ABEX TCD-726

Errors total
Num: 1
Errors (Loudness) dB(A)
Num: 1
Avg: -63.2 dB(A)
Max: -63.2 dB(A)
Error Muting Samples

Skips Samples

Max: 0 Samples
Total Test Result
95.9 points (out of 100.0 maximum)
C2 Accuracy 50.0 %

The behavior of drive was much better in this case where it managed to correct almost all the disc's errors. However a single error is responisble for the 95.9 total test result.

- CD-Check Audio Test Disc

In order to evaluate the sound reproduction and error correction capabilities of a CD player (currently the Action 16),
we used the CD-Check Audio Test Disc. The disc, designed and manufactured with error patterns,contains five tracks, with each track progressively harder to read and reproduced by the CD player. These tracks are referred as Check Level -1 through Check Level -5.

Using a software multimedia player, such as Windows Media Player in this case, the five tracks are reproduced, with a clear and successful reading on each track, as long as the tone reproduced is smooth, uninterrupted, without any skips or loops. Each of the levels passed, is a percent of the reliability of the sound reproduction of the tested device.

The drive passed only the first three Check Levels of the test. The performance reveals average sound reproduction and error correction. The fourth and the fifth levels include an error size of 1.125mm and 1.500mm respectively, and the drive produced continues audible clicks over those tracks.
