Cartridge arrangementwith a data storage medium.

摘要

A hard disc cartridge arrangement 10 includes a housing 12 and a hub clamp 22 which cooperate so that the hub clamp 22 firmly and precisely engages the spindle of a disc drive, and a door arrangement 24 which allows the heads of the disc drive to enter the cartridge 10 from the upper and lower surfaces 14, 16 of the cartridge 10. The door 26 is locked in the closed position to prevent contact with the data storage media and is urged to a positive open position so that it does not interfere with the placement of the heads adjacent the disc 20.
