摘要： 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.

摘要： A low profile, high capacity, high performance disk drive includes a plurality of disk surfaces mounted in parallel for simultaneous rotation about an axis. Each of a plurality of data transducer heads for reading and/or writing data to the data surfaces is attached to a slider. A stacked arm actuator for moving the data transducer heads in a radial direction across the disk surfaces includes a supporting arm and a suspension load beam attached to the supporting arm. The suspension load beam connects the supporting arm to the slider. The suspension load beam includes a load dimple bearing on the slider and has opposed stiffening flanges extending in a plane adjacent the slider. The actuator includes a stack of 9 head arm suspension assemblies and the stack has a height of 16.634 mm. An interdisk spacing of less than 1.4 mm provides a height dimension of 14.635 for a stack of 8 disks. Shock and electrical isolation is accomplished using four mounting blocks carrying energy absorbing, highly damped, resilient material.

摘要： A disk drive has at least one disk for storing data and at least one transducer for reading or writing data to or from the disk. The transducer is attached to an actuator which positions the transducer with respect to the disk. The actuator includes a controllable motor which is used to move the actuator and the transducer attached thereto. The disk drive also includes a ramp for off loading the transducer or for parking the transducer off of the surface of the disk. The disk drive includes a combination shock absorber and gasket that has locking tabs to keep the combination shock absorber and gasket in place during a shock or impact loading event. The combination shock absorber and gasket also can be provided with additional extensions to lessen shocks caused by flat drops. Elastomeric blocks or pads can be provided on the cover and the base to lessen shocks caused by flat drops. The drive can also have rotatable elastomeric blocks that can rotate to a position above the disk drive to lessen shocks resulting from flat drops. The drive also is provided with a shock sensor which provides visual evidence that the drive has undergone a shock of a predetermined threshold. Another shock absorbing system uses a shroud around the connector on the disk drive.
