The cartridge has a hub (12) connected proximate to the center of the magnetic recording surface. The hub has a 45 deg angled peripheral edge (12b) adapted to selectively engage an edge of a spindle access opening. During translation into drive, hub and media (14) are translated along the z-axis within shell as the cartridge is translated linearly. Coupling of the spindle and cartridge in the disk drive is achieved through the use of a media hub formed on the disk cartridge. The media hub is formed of a ferrous material with an 8 micro inch finished surface for friction reduction. The hub comprises a bore (12a) proximate the center of the hub, peripheral outer edge, and inner ring surface (12c). The peripheral edge defines a 45 deg outer surface and a circumferential ring around the hub, that is adapted to selectively engage with a rounded edge of the spindle access opening (18c) during upward translation into the shell (18). The hub defines a stepped profile and the disk is attached to the hub along the topmost surface. A step down from the surface provides a gap between the hub and the disk which provides additional flexibility for vertical translation of hub within cartridge. The spindle is formed to complement the structure of the hub: a z-datum (40a); a round boss surface (40b) and; a conical lead-in groove (40c), enable engagement and disengagement of hub from spindle (40). The spindle is also magnetically sensitized to attract and magnetically couple the hub to spindle. INDEPENDENT CLAIMS are also included for the following: A removable media disk drive and; A removable media disk drive system and; A disk cartridge for use in a storage device.
