Preparations 3 Chapter

The disc is ejected.

After removing the disc, you do not need to return the screw to its original position. Normal operation will resume when the unit is powered on again.

3 Close the rubber cover firmly.

3-6-7 Handling of Discs When

Recording Does Not End

Normally (Salvage Function)

Recording processing does not end normally when the primary power 1) of this unit is lost 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 control panel is set to standby, because the unit does not enter standby mode until after the end of recording processing.

1)Primary power is lost when the AC power switch on the rear panel is turned off, the AC power cord is disconnected, DC power is turned off, the battery pack is exhausted, the battery pack is removed, and so on.

Notes

•Do not turn this unit’s primary power off until recording processing has finished and the ACCESS indicator has gone out.

•This function salvages as much recorded material as possible after an unforeseen accident, but 100% restoration cannot be guaranteed.

•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 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.

1 Insert the disc on which recording did not end normally.

The message “Salvage ?” appears.

2 Do one of the following.

To salvage

Press the SET button.

Processing begins and the message “Executing.” appears.

Notes

•If the REC INHI indicator (see page 18) is lit, the message “EJECT?” appears. Eject the disc, set the Write Inhibit tab to the recording enable position, and insert the disc again.

•This operation cannot be cancelled once it begins.

The message “Complete” appears when processing finishes. If the message reads “Incomplete!,” the clips that failed were lost.
