ABSTRACT:
An optical disk having radially discrete main and lead-in track areas in which there are respectively recorded color video information according to one of a plurality of TV systems, such as, NTSC and PAL systems, and code data including data identifying that one TV system, is reproduced by an optical disk player including a head for initially scanning and picking up the code data recorded in the lead-in track area and then scanning and picking up the color video information recorded in the main track area. The output of the head is supplied to a reproducing circuit having at least one operating mode corresponding to a predetermined one of the TV systems for processing the color video information from the output of the head when the TV system used for recording is consistent with the predetermined one of the TV systems corresponding to the operating mode, the identifying data is decoded from the output of the head when the latter scans the lead-in track area, and a function of the optical disk player is controlled in response to an inconsistency between the predetermined TV system corresponding to the operating mode of the optical disk player and the TV system used for recording as determined from the derived identifying data. The function thus controlled may be the operation of an indicator or a disk ejector, the generation of a display or message on a monitor, or the change-over of the operating mode of the disk player.
