e Playback condition mark
One of three channel condition marks is displayed when
the ACCESS indicator is lit. The three channel condition
marks indicate the following three stages.

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 7-2-2 “Basic Menu
Operations” (page 69).

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.
