Playback condition displays
You can be alerted in advance to deteriorating playback
conditions and to error correction rates which are
approaching their limits.
Deteriorating playback may be due to the following
causes.
• Scratches and dust on the disc surface
This includes fingerprints, dust from the air, tar from
cigarette smoke, and so on.
Scratches and soiling which occur before recording are
not a problem because they are registered in advance as
defects, and recording avoids them. However, scratches
and soiling which occur after recording can lead to
deteriorating playback conditions.
• Aging of disc recording layers
Over several decades, the recording layers of optical
discs can age and cause deteriorating playback
conditions.
You can use this function to check archival discs and
other discs which have been stored for extended periods,
so that you can take action before the deterioration
progresses further.
• Deteriorating laser diodes performance
The performance of the laser diodes used in optical
heads can worsen with age, leading to deteriorating
playback conditions.
You can use the digital clock to check the total optical
output time of optical heads.
