Abstract
A method and device for playing a composite disk containing separate audio-only and video-plus-audio portions in which the time until the commencement of the playing of the video-plus-audio portion is reduced. When playing of only the video-plus-audio portion is designated, a data detection point of the pickup is immediately moved toward the lead-in area of that portion, whereupon reproduction is started immediately. In another embodiment, index data is directly read from the lead-in area of the video-plus-audio portion without reading similar data for the audio-only portion. When the playing of the video-plus-audio portion is completed, the pickup is stopped at a rest position corresponding to the lead-in area of the second region.
