Abstract: Disclosed is an apparatus and method for correcting for track misregistration when a slider or head assembly contains a separate read element (40) and write element (42). Basically, the offset is determined at a first position and at a second position of the actuator arm (48) assembly. From these offsets a constant and a multiplier are determined for determining an offset as a function of the cylinder location. Also disclosed is a method and apparatus for minimizing distance traveled to prevent misregistration when repositioning between the read element and a write element. The read element is intentionally offset from the write element at an angle so as to minimize the distance traveled across the disk.

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.
