Abstract
A disk player has a guide member for guiding an optical pickup carrier along both sides of a double-sided disk. In order to prevent interference between the pickup carrier and the periphery of the disk during turning movement of the pickup carrier around the periphery of the disk from one of the upper and lower sides of the disk to the other side, the guide member is shaped like a horseshoe. The guide member includes upper and lower straight sections for guiding the pickup carrier, respectively, along the upper and lower sides of the disc, and an arched section extending vertically around the periphery of the disk and connecting the outer ends of the upper and lower straight sections. The upper and lower straight sections are not parallel to each other, but rather they are inclined in such a fanlike manner that the outer ends are wider apart.
