Abstract: A clothespin-like gripper having a pair of clamp jaw portions resiliently urged together and adapted to embrace and thereby grip a magnetic diskette or disk-jacket assembly for pulling the diskette from an original position into a final position. A swingable blocker is provided on the gripper so that the diskette is thereby blocked from being embraced by the gripper whereby the gripper may be used to move the diskette back from its final position into its original position without any embracing action by the gripper.

Abstract: A diskette identifying code is written in each sector on a flexible disk used in a flexible disk recorder. The diskette identifying code can be read from any track on the flexible disk and used to log the occurrence of insertion or removal of the diskette at the flexible disk recorder. Also, the diskette identifying code can be read from any accessed track prior to a write operation on that track in order to verify that the diskette has not been changed by the operator since the last access to the flexible disk.
