  • Ultra-high capacity removable media cartridge configured to prevent insertion in a conventional floppy disk drive
    Patent number: 5748420
    Abstract: A removable media diskette cartridge configured for use with an ultra-high capacity disk drive, and precluded from use with a conventional floppy disk drive, includes a top casing half with a substantially flat front edge which overhangs the front edge of the shutter, thus preventing the shutter from being engaged and opened by a conventional shutter opening mechanism. The diskette cartridge also includes an area of increased thickness which prevents the diskette from being inserted through the access opening of a conventional 3.5" floppy disk drive.
