3-5-7 Handling of Discs When
Recording Does Not End
Normally (Salvage Function)
Normally (Salvage Function)
Recording processing does not end normally if, for
example, the POWER switch on the rear panel is turned off
during recording, or if the power cord is disconnected
during recording. Because the file system is not updated,
video and audio data recorded in real time is not
recognized as files and clip contents recorded up to that
point are lost.
However, this unit has a salvage function which can hold
losses to the minimum by reconstructing clips on such
discs.
Note that no recorded clip contents are lost when the on/
standby switch on the front panel is set to standby, because
the unit does not enter standby mode until after the end of
recording processing.

• Even when this function is used, it is not possible to
recover data from immediately before the interruption of
recording. The amount of data lost is as follows.
- Quick salvage: From 2 to 4 seconds of data before the

- Quick salvage: From 2 to 4 seconds of data before the
interruption of recording.
- Full salvage: From 4 to 6 seconds of data before the
interruption of recording.
Quick salvage
When the unit is powered on again after a recording
interruption due to power off, with the disc still loaded in
the unit, clips are reconstructed on the basis of backup data
stored in nonvolatile memory and markers recorded on the
disc.
Processing time is about 5 seconds.

Full salvage
When a disc that was manually ejected from a device
subjected to a recording interruption due to power off is
loaded into this unit, clips are reconstructed on the basis of
markers recorded on the disc. Nonvolatile memory cannot
be used, so processing takes longer than for a quick
salvage (about 30 seconds, although it depends on the state
of the disc).
Proceed as follows to perform a full salvage.

To exit without salvaging
Press the RESET button.

its contents will be lost.)
