ABSTRACT:
A high density and high data rate disk drive with multi-arm-track-per-head access is disclosed. Small track width and small track pitch are achieved with small head-to-media distances and thin film magnetic head access arm. Track seek movements are totally eliminated for disk access. A plurality of thin film magnetic read/write heads is etched into a magnetic head arm. An assembly of a plurality of said magnetic head arms is provided to position each of said arms over each surface of each disk on said disk drive. An apparatus is structured with each assembly of said magnetic head arms to provide adjustment of track-head misalignment caused by environment temperature changes to eliminate thermal induced misregistration (TMR) effects. A plurality of said assemblies of magnetic head arms is provided to position multiple arms over the same surface of a disk, and over all surfaces of all disks, on said disk drive.
The magnetic head cross talk misregistration (CMR) and thermal induced misregistration (TMR) effects are totally eliminated. Removal of CMR effects is accomplished by etching a plurality of thin film magnetic read/write heads into an access arm while that of TMR effects is achieved through said TMR removal apparatus.
