CD Error Correction Tests

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.

- ABEX TCD-721R

The performance with the 721R test disc is about average. The drive reached a very high -9.6 dB(A) Error Loudness level and also skipped samples. The drive cannot return C2 error pointers, so there's no C2 Accuracy score.

- ABEX TCD-726

The Abex TCD-726 test disc is much easier for drives in general to read. The Pioneer DVR-108 drive reached 92.2 score (out of 100), a good score.

- 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 being reproduced through a software multimedia player (i.e. 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 showed a good ability to correct errors and reached the 5th level where it managed one out of five.
