るデイスク再生装置。[Claims for Utility Model Registration] A disk-shaped recording medium in which multiple types of information using different frequency bands are recorded in different areas on the same disk surface, and a disk-shaped recording medium in which information in different frequency bands is recorded on the disk-shaped recording medium. A driving means for changing speed and rotationally driving the disc-shaped recording medium and a detecting means for reading the plurality of types of information recorded on the disc-shaped recording medium are moved in a radial direction parallel to the recording surface of the disc-shaped recording medium. In a disc playback device having a moving means for driving, when the detection means provided corresponding to the boundary position of each of the plurality of types of information and supported by the movement means reaches the boundary position of each of the information. 1. A disc playback device comprising a position detection switch for detecting.
