Abstract
A disk assembly, which includes a large number of magnetic disks arranged in layers on a disk loading hub, is detachably mounted on a rotating shaft of an air spindle motor that is set on a base. The base has thereon a movable table capable of reciprocation. The movable table carries thereon a rotary positioner for rotating and positioning a stacked head assembly, which is formed of a large number of magnetic heads stacked in layers, and a plurality of ramps for loading into and unloading the magnetic heads from the magnetic disks. The distance between the respective rotating shafts of the air spindle motor and the rotary positioner can be adjusted by moving the movable table.
