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: 1114385|
|Errors (Loudness) dB(A)||Num: 53206||Avg:-73.4 dB(A)||Max: -21.9 dB(A)|
|Error Muting Samples||Num: 3569||Avg: 1.0 Samples||Max: 11 Samples|
|Skips Samples||Num: 0||Avg: 0.0 Samples||Max: 0 Samples|
|Total Test Result||76.6 points (of 100.0 maximum)|
|C2 Accuracy||99.7 %|
According to the above graph and our experience, the overall performance with this test disc is quite good. The total error count is average while there were no skipped samples. The Total Test Result score is quite good and indicates a drive capable of good error correction.
- ABEX TCD-726
|Errors total||Num: 0|
|Errors (Loudness) dB(A)||Num:0||Avg: 0 Samples||Max: 0 Samples|
|Error Muting Samples||Num: 0||Avg: 0 Samples||Max: 0 Samples|
|Skips Samples||Num: 0||Avg: 0 Samples||Max: 0 Samples|
|Total Test Result||100.0 points (out of 100.0 maximum)|
The response of drive with this test disc was much better where it managed to correct all the disc's errors. The result was a perfect 100.
- 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 ability 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 tracks 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 only the first three Check Levels of the test. The performance reveals average performance with the specific test disc. 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.
