Abstract: A direct access storage device (DASD) includes a plurality of motion limiters and/or a continuous motion limiter projecting from at least one of the base and cover, each motion limiter having faces disposed in close proximity to and confronting opposite surfaces of a data storage disk adjacent a peripheral portion of the disk that does not contain data. Preferably, the motion limiters are disposed at several points about the periphery of the disk, and may be incorporated in a load/unload ramp and/or side rails of the DASD. The faces of the motion limiters are disposed relative to the disk so that when the DASD is subjected to an acceleration, the disk contacts at least one of the faces only at the peripheral portion of the disk, outside the data zone. Accordingly, the motion limiters prevent data zone and spindle bearing damage when the DASD is dropped.

Abstract: A direct access storage device (10) includes a plurality of motion limiters (48) and/or a continuous motion limiter (48) projecting from at least one of the base (12) and cover (58), each motion limiter (48) having faces (55, 57) disposed in close proximity to and confronting opposite surfaces (38, 39) of a data storage disk (14) adjacent a peripheral portion (42) of the disk that does not contain data. Preferably, the motion limiters (48) are disposed at several points about the periphery of the disk, and may be incorporated in a load/unload ramp and/or side rails of the direct access storage device. The faces (55, 57) of the motion limiters (48) are disposed relative to the disk so that when the direct access storage device (10) is subjected to acceleration, the disk contacts at least one of the faces (55, 57) only at the peripheral portion (42) of the disk, outside the data zone (40). Accordingly, the motion limiters (48) prevent data zone (40) and spindle bearing (34) damage when the direct access storage device (10) is dropped.
