An information storage device ( ) includes a cradle ( ) which can removably receive a cartridge ( ). The cartridge has a sealed housing ( ) which contains a rotatably supported disk ( ), and a pivotal actuator arm ( ) that supports a magnetic head ( ) for movement adjacent the disk. When the cartridge is removed from the cradle, the head is moved to a parked position with respect to the disk, in which a magnetically permeable part ( ) on the actuator arm is in close proximity to a magnetic arrangement ( ) disposed within the housing. The magnetic arrangement exerts a strong magnetic force that resists movement of the arm and head away from the parked position. The cradle has a shunt ( ) which, when the cartridge is removably inserted, interacts with the magnetic field through a wall of the sealed housing, in a manner which reduces the effective magnetic force that tends to retain the arm and head in the parked position.

A disk drive has a sleeve-bearing spindle motor having a rotor for rotating the disk of removable data storage cartridge. A retainer which is compliant in the direction of axial movement of the rotor stops the axial movement. The retainer is mounted on a moveable platform which mounts the disk cartridge as it is inserted into the drive. The retainer includes a cantilevered beam which is compliant in the direction of axial movement.
