ABSTRACT:
Two versions of an improved device for preventing unauthorized access to computer, video, and audio and like disk and cassette drives are described. Drives with an existing external latch that prevents insertion or removal of the disk, such as standard 51/4 disk drives, are secured by means of an inserted plate which captures the latch in the closed position, combined with an external locking assembly which prevents movement of the inserted plate. Drives and players with an internal mechanism that moves the disk or cassette to a play position, for example 31/2 disk drives, are secured by means of inserting a modified disk or cassette that has an attached plate that extends outside the drive when the disk or cassette is in playing position. A locking assembly with a plate to jamb the modified disk or cassette in position is locked to the extending position.
