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.

Abstract: A method and apparatus (10, 410) for testing magnetic media read/write head components such as a head element bar (46) and a slider assembly (546). The component to be tested is held in a head bar holding assembly (44) or an alternate head holding assembly (544), and positioned with a head gross positioning assembly (18) or a head fine positioning assembly (16) over a localized portion (50) of a flexible magnetic medium (28) which is caused to spin in relation to a stabilizer plate (20) by a media spin motor (28). The localized portion (50) is deformed to bring the localized portion (50) of the flexible magnetic medium (28) into proximity with the component under test.
