a)Read errors will occur if the playback condition continues to deteriorate. If a read error occurs, a “Disc Error!” alarm appears in the time data display, the picture freezes, and audio is muted.
To display playback condition marks, set basic menu item
012 “CONDITION DISPLAY ON VIDEO MONITOR” to “ena,” and set basic menu item 005 “DISPLAY INFORMATION SELECT” to “T&sta.”
For details about operation, see
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.
