Abstract: 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 disc (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 disc (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).
