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.

Abstract: The system of a disk with a spindle motor (16) is provided with an improved tripping mechanism of an arm assembly (34, 36) where the arms (34) are independently and individually retractable and extendable from a tipping member (36). In addition thereto each arm is individually self-locking in the tripping member (36) without necessity of external fasteners, such as bolts, springs and rings. Due to the fact that the arms (34) are individually retracted/extended they can be manufactured very thin enabling thus easy attachment of a suspension assembly of heads (33) to the arm (34) without necessity to die forging, adhesive bonding, welding or screwing together. Because the arms can be very thin, a substantial reduction of mutual distance of disks (12)from each other and thus substantial reduction of the total height of the disk driving system can be achieved.

Abstract: A secondary data storage system for a host computer system includes a disk drive system having a device controller, at least a first magnetic disk and a read/write magnetic transducer positionable with respect to a recording surface of each magnetic disk. A write operation exposes data on adjacent tracks to potential damage if an off track condition occurs to the transducer during a write. A method for controlling write operations through the device controller provides backup of data in tracks adjacent to a target track for the write operation prior to the write operation occurring. The method detects occurrence of events resulting in an off track condition of the magnetic transducer relative to a target track. Occurrence of such an event triggers a determination of damage to the contents of tracks adjacent to the target track and restoration of those tracks. Write operations to the target track are blocked until shock events discontinue.
