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.
Claims45
A sealed cartridge adapted for selective use in a disc drive which disc drive has a first electromagnetic actuator means, said sealed cartridge comprising:
- a sealed housing;
- a disc positioned in said housing;
- a magnetic head positioned in said housing adjacent said disc so that data can be transmitted to or read from said disc;
- means for rotationally mounting said disc in said housing;
- second electromagnetic actuator means attached to said magnetic head within said sealed housing, the first electromagnetic actuator means spaced from said second electromagnetic actuator means with the cartridge located in the disc drive, said second electromagnetic actuator means for moving said magnetic head relative to said disc due to an electromagnetic field produced between said second electromagnetic actuator means and the first electromagnetic actuator means;
- and
- magnetic coupling means for magnetically coupling said disc to the disc drive, in order to allow the disc drive to rotate said disc, without the magnetic coupling means physically touching the disc drive.
