Magnetic disk storage device with the base provided by an electronic module substrate

摘要

High density magnetic disk storage and semiconductor module technologies are combined to provide a disk drive using a standard multilayer ceramic substrate as the disk drive base support member to support spindle and actuator assemblies including 1 inch diameter disks. The ceramic substrate has components and very large scale integration (VLSI) chips mounted directly thereon to avoid use of one level of packaging and presents standard pins to mount the drive using standard sockets to afford economy and reliability.
