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.

The performance with this disc is both good and bad. The total error count
was very high, but the maximum error loudness level at -35.6dB
is quite low and there were no skipped samples. The final score of
69.9 is about average.

The Abex TCD-726 test disc is much easier for drives in general to read. However,
the TDK 882N performed rather poorly here and the score of
71.6 is very low for this 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 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 (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 successfully passed only the first two out of the five check levels
for this test. Once again the drive had poor performance. On average,
most drives will pass up to level 3, a good drive can read the 4th
level, while all but the best drives have difficulties
reading the 5th level.
- Summary
Generally we can say that the CD error correction of the TDK 882N is sub
par, something that hopefully will be fixed with newer firmware updates...
