Abstract: High density magnetic disk storage and semiconductor module technologies are combined to provide a disk drive using a standard multilayer ceramic substrate 10 as the disk drive base support member to support spindle 14 and actuator assemblies 25 including 1 inch diameter disks. The ceramic substrate has components and VLSI chips 40, 41 mounted directly thereon to avoid use of one level of packaging and presents standard pins 44 to mount the drive using standard sockets 45 to afford economy and reliability.

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: A disk drive storage system comprises an array of disk drive units (230). The disk drives (160) contained in the units have a diameter of 65mm and rotate at 10,000 RPM which has the effect of reducing latency. In a preferred embodiment data and corresponding parity information are converted into portions and stored on a respective different one of the disk drive units. Data stored on a filed disk drive unit can be regenerated on a replacement disk drive unit. A disk drive unit can be replaced without powering down the system. Four disk drive units can be arranged in a four drive system to match the space geometry of the traditional half-high flexible disk drive used in a personal computer.
