ABSTRACT:
A sealed cartridge 22 vor selective use in a disc drive 20 includes a sealed housing 70 with a disc 72 positioned therein and heads 80, 81 positioned relative to the disc. An actuator mechanism 84 is provided for use with an actuator arrangement 47 of the disc drive 20 in order that the actuator mechanism 84 and the actuator arrangement 47 can cooperate to move the heads 80, 81 relative to the disc 72. A magnetic coupling mechanism 77 is adapted for magnetically coupling the disc 72 to the disc drive 20 in order to allow the disc drive 20 to rotate the disc 72, without the magnetic coupling mechanism 77 physically touching the disc drive 20.
