Abstract
Abstract Information storage disk equipment for handling and storing interchangeable disks, including disk loading and rotating mechanism, a disk package and a transfer system. The loading and rotating mechanism has a disk chuck and is movable from a lowered disk release position to a raised position close to the sensing heads. The disk package is releasable and reversibly mounted in the equipment. It consists of an enclosure, an information storage disk having two flat magnetic or other recording surfaces and a disk transport with a central opening surrounding the disk providing free access to each face of the disk. The disk transport and the disk therewithin are slidably mounted within the enclosure for movement to and from it. The disk transfer system moves the disk transport with said disk between a position within the enclosure to the disk release position, with the disk transport remaining at the disk release position while the disk is moved to the raised disk position by the chuck, the disk enclosure remaining in the equipment until the disk transport with said disk are returned by the transfer system. The equipment may also prevent ''''write'''' operation of a ''''read'''' condition disk, by the provision on the enclosure of a selective condition indicator for each side of the disk.
