Error Correction Tests

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

- ABEX TCD-721R

TEAC DV-W58G-A had a good performance with the Abex 721R test disc. The maximum error loudness at -36.0 dB(A) is low, which means that there is no case of experiencing audible errors.

- ABEX TCD-726

The 726 Abex test disc is easier for most drives to read. Teac drive just ignored the defected area on the disc.

- 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 reading music abilities and reproduce it completely. Five tracks on the disc contain a progressively difficult sequence. These tracks are referred to 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 drive.

The TEAC drive played only the first three levels of the CD-Check Audio test disc without noticeable clicks. The fourth and fifth levels produced continuous audible clicks. The performance is acceptable but we expected to be better.

- Summary

The average score for the TEAC DV-W58G with the Abex test discs is 88.35 points. The performance is very good, but we cannot say the same for the CD-Check Audio Test Disc.
