媒体用再生装置。[Claims for Utility Model Registration] An apparatus for reproducing a disc-shaped information recording medium on which concentric or spiral tracks are formed divided into sectors each consisting of an address field and a data field, the disc-shaped information recording medium comprising: a driving section that rotationally drives a recording medium; a reproducing section that reproduces an information signal from a track of the rotationally driven disc-shaped information recording medium; and a reproducing section that rotates the reproducing section in a radial direction of the disc-shaped information recording medium. a transfer section that transfers the information signal at a pitch narrower than the width of the target track; a memory section that demodulates the reproduced information signal, stores the information signal in units of sectors, and outputs the information signals; and an information signal in units of sectors from the target track. 1. A playback device for a disc-shaped information recording medium, comprising a control unit that controls the movement of the playback unit according to a playback status of the playback unit.
