ABSTRACT:
A disk reproducing device that has two guide rails disposed at both sides of a disk and that reads data recorded on both sides of the disk using a single pickup device (21) by moving the pickup device along the guide rails. Each guide rail is composed of two linear guide shafts connected by an arcuated guide section (15). The arcuated guide section has a diameter smaller than that of the linear guide shafts, joints connecting the guide shafts and the guide section have tapering shapes, and a plurality of turning bearings are disposed on the pickup device. The pickup device can therefore move smoothly. In addition, all guide shafts can be swung substantially equally by swinging only one linear guide shaft thereby permitting a tilt adjustment to be executed by a single motor. The apparatus further has an adjusting member composed of a flat spring, a screw and other parts, to adjust a position of the pickup device relative to the disk.
