A disc drive 20 including a spindle motor assembly 42 having a magnetic clutch plate 46 and an actuator 47 receives a hermetically sealed cartridge 22 containing a plurality of discs 72, 74 with associated heads 80, 81 mounted in the cartridge 22. Associated with an arm assembly 84 which supports heads 80, 81 is a component 50 for use with the actuator 47. With the cartridge 22 inserted in the drive 20, the actuator 47 operates to cause the heads 80, 81 to traverse relative to the discs 72, 74 as the spindle motor assembly 42 uses a magnetic field to engage a magnetic plate 77 associated with cartridge 22 in order to spin the discs 72, 74. Data transfer connectors 52, 54 are associated with both the drive 20 and the cartridge 22 in order to allow for the transfer of data between the cartridge 22 and the drive 20.

High density disc drive with magnetic clutch for use with a sealed

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.
