3-5-6 To Eject Discs With the Unit Powered Off

As an emergency measure, disc cartridges can be removed with the unit powered off. However, the cover must be removed. This operation should always be done by a trained service technician.

For details, refer to the Maintenance Manual.

3-5-7 Handling of Discs When

Recording Does Not End

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.

Notes

Do not set the POWER switch on the rear panel to 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 INH indicator (see page 24) is lit, the message “EJECT?” appears. Eject the disc, set the write-protect tab to the recording enable position, and insert the disc again.

This operation cannot be cancelled once it begins.

A message appears to display the results when processing finishes. If the message reads “Incomplete!”, the clips that failed were lost.

To exit without salvaging

Press the RESET button.

The state of section where recording was interrupted is saved, but no salvage processing is done.

Sections which were recorded normally can be played back, but no new recording can be done on the disc. (A quick format can be done on the disc, although all of its contents will be lost.)

Note

Unless clips are salvaged, the message “Salvage ?” appears again the next time the disc is inserted or the unit is powered on.
