Abstract

PURPOSE:To simplify the driving structure of turntable control and make it possible to obtain a stable operation by linking a brake unit to a driving mechanism in a prescribed positional range of a reproducing converter structure. CONSTITUTION:Turntable 2 to rotate optical disc 1, reproducing converter structure 3 provided with detection elements 4-7 to detect signals of disc 1, and driving mechanism 12 to move structure 3 in the radius direction of disc 1 are provided. Brake units 22-23 to damp table 2 are linked to mechanism 2 in a prescribed positional range of structure 3, thereby damping table 2. In this case, structure 3 is moved by linkage between pinion 13 of driving mechanism 2 and fixed rack 8 in the recording range of disc 1, and movable rack is moved by linkage between pinion 13 and movable rack 9 outside the recording range, and brake unit 22 responds to movement of rack 9, thereby damping table 2.
