- the contents 1 and 2 recorded in the area 1 of the storage unit 340 are both recorded on the disc 1 (FIG. 9). That is, the content 2 is in a synchronized state.
- the timing of performing such content synchronization processing may be immediately after the disc 1 is loaded in the drive unit 300, or may be performed at any time during the period from loading to removal.
- the synchronization process may be performed at a timing at which the recorder device 100 or at least an idle state in which the drive unit 300 is not used.
- the content synchronization processing is not performed at this time, and the disc 1 is loaded into the drive unit 300 next time. Sometimes it can be done.
- the recorder device 100 when the disk 1 is loaded in the drive unit 300, the recorder device 100, or at least the drive unit 300, is necessary for performing the synchronization process such as when the reserved recording starts immediately in the standby state for the reserved recording. If it is found that a sufficient amount of time cannot be secured, the content synchronization process is not performed at least immediately, or the synchronization process is not performed while the worst recorder apparatus 100 is activated this time, and the next recorder apparatus It may be performed when 100 is activated and the disk 1 is loaded.
