Abstract
An image information processing apparatus comprises a rotational shaft for supporting five optical disks, subjected to read or write access, at predetermined intervals along its central axis, and two optical units, each having an optical head rotatable through 180 degrees to allow scanning of positions separated by 180 degrees. The optical heads are moved along the central axis of the rotatable shaft and in a radial direction of the optical disk between a scanning position where the optical disk can be scanned, and into a non-scanning position where the optical disk cannot be scanned. Thus the optical heads are moved to face different positions on the same optical disk or different optical disks.
