Disk Recorder/Extended VTR File
Operations
Internally, disk recorders and Extended VTRs manage
recorded material in units of files.
When using disk recorders and Extended VTRs for
playback and recording, you need to perform the following
file operations.
Loading file lists: Before you can play a file from a disk
recorder or Extended VTR, you need to display a list
of the files stored on the device.
Loading files: With the file list visible, you need to select
a file from the list to load.
Creating files: To record to a disk recorder, you need to
create the file to record.
Note
When using an MAV-555A/777 disk recorder to carry out
file operations, the operation mode must be set to panel
mode on the disk recorder side.
