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.

Total Test Result |
69.6 points (of 100.0 maximum) |
Average performance with this test disc. A very high total error count, the error loudness is rather high too at -6.1 dB(A) and there were also 2
samples skipped. A total test result score of 69.6 points is indicative
of an average
test
rating.

The Abex 726 test disc is usually much easier for drives to read in most cases.
Normally, most drives manage a test result score of 100 or close to but this
is not the case here. With an overall score of 84.0 points, the drive's performance
can simply be characterized as good.
- 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.

The drive successfully passed three out of five check levels for
this test. This is average performance but a"good" drive will read up to the fourth level and the very best drives manage to read the fifth track.
- Summary
The CD error correction capabilities of the drive are average although
performance with the ABEX TCD-726 test disc was disappointing where we expected
better results.
