Abstract
A disk player for double-side disks, such as video disks, having a reduced overall size and simplified structure. The pickup, spindle, spindle motor, and disk clamper of the player are mounted on a rotary frame. To change from playing one side of the disk to the other, the disk is conveyed out of the player, the rotary frame is rotated through 180 degrees, and the disk conveyed back into the player. The disk is then again clamped against the spindle and played.
