Abstract
A disc drive (420) includes a spindle motor (432) having a stator assembly (436) which is provided in a radial gap configuration. A removable cartridge (422) includes a rotor assembly (472) mounted on a bearing arrangement (468) which additionally mounts the disc (430) contained in the cartridge (422). When the cartridge (422) is placed in the drive (420), the rotor assembly (472) of the cartridge (422) comes into alignment with the stator assembly (436) of the drive (420) so that the spindle motor (432) can cause the disc (430) contained in the cartridge (422) to rotate at the proper speed.
