Deleting The Recorded Clip - Sony POWER HD FX PDW-700 Operation Manual

To play back a clip, press the PREV button to
move to the start frame of any clip, or press the
F REV button to move to any position.
After disc insertion
The unit stops at the position of the disc when it
was most recently ejected.
Press the PLAY/PAUSE button to resume
playback at the most recent position.
The playback position is saved to the disc when
the disc is ejected, which allows playback to start
at that position whenever it is loaded into any
XDCAM player.
Note
The playback position is not recorded to the disc if the
disc is write-protected.
Deteriorating playback conditions
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.
• Deteriorating laser diodes performance
The performance of the laser diodes used in
optical heads can worsen with age, leading to
deteriorating playback conditions.
Refer to the Maintenance Manual for an
approximate guide to when it is time to replace
optical heads.
To prevent playback conditions from
deteriorating
Pay attention to the following points when
handling discs.
• Do not open disc cartridges and touch discs
directly with your hands.
• Do not store for long periods in locations which
are dusty or exposed to air circulated by fans.
• Do not store for long periods under high
temperatures or in locations exposed to direct
sunlight.
If playback conditions have deteriorated
Read errors occur when playback conditions
continue to deteriorate.
When a read error occurs, the message "DISC
ERROR!" appears, the video freezes, and the
audio output is suppressed.
If this happens, check the following points.
Whether the disc displays the same playback
condition on other XDCAM devices: If so,
the surface of the disc may be dirty or
scratched, or the performance of the
recording layers on the disc may have
worsened due to age. Do not use discs with
these symptoms.
Whether every disc inserted into an XDCAM
device displays the same playback
conditions: If so, the performance of the
laser diodes may have deteriorated. Check
the total optical output time.
