ABSTRACT:
A magazine in a disk player stores disks therein. A transport mechanism transports a selected one of the disks between the magazine and a disk reader. The disk reader is positioned to read a selected disk while a center aperture of the selected disk overlaps disks remaining in the magazine. A first embodiment has three edge rollers which engage an edge of the selected disk to rotatably support the selected disk at the read position. One of the edge rollers which is external to the magazine is driven by a driver mechanism to rotate the selected disk for reading. A second embodiment includes carriages for supporting the disks in the magazine and at the read position. The carriages each have a rotatable shaft for engaging the center apertures of the disks. When a selected disk is moved to the read position, a pair of idler rollers and a driving roller engage top and bottom surfaces of the selected disk. The idler roller is driven by a driver mechanism to rotate the selected disk. The idler roller is angled with respect to either a radius or a plane of the selected disk to impart a radial bias upon the selected disk.
