PROBLEM TO BE SOLVED: To provide an optical disk device of a disk changer system in which a video recording mode can be set with respect to total programmed video recording time, considering total free space of a plurality of recordable optical disks which are placed on a rotary tray. SOLUTION: When the rotary tray is closed, disk management information are read out from each optical disk and total free space for the plurality of optical disks are calculated. When a certain television program is programmed to be recorded, a total recording time for timer recording is calculated, and the total recording time is compared with the recordable time for values of the total free space and the recording mode is set. When recording instruction by timer recording is performed, video a program is recorded in the initial optical disk, and when disk capacity becomes full, the program is recorded in the next optical disk. And, when disk capacity becomes full, the program is recorded in the further next optical disk. When recording for the timer recording is finished, this processing is finished.
