    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 load/unload device to remove the slider from the proximity of the magnetic recording surface of a disk in a disk drive whenever the disk is to be stopped is disclosed. The load/unload device is a ramp-like wedge which extends generally radially from the center of the magnetic disk and to the magnetic recording surface of the magnetic disk. When the slider is moved toward the center of the disk by an actuator mechanism, the end of the load arm supporting the slider, referred to as a tang, will engage the inclined plane of the wedge and lift the slider from the surface of the magnetic disk as the slider is translated closer to the center of the disk. Once the slider has been removed from close proximity of the disk, the tang may engage a trough-like surface on the structure supporting the wedge and will effectively detent the position of the slider through the forces exerted on the tang by the load beam of the actuator. Thus the disk will be protected from undesirable and damaging impacts of the slider against the magnetic recording surface of the disk thereby prolonging disk utility.

    Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.
