Abstract

In a random access disk storage system, a multiplicity of magnetic head assemblies must be precisely aligned radially relative to a stack of concentric rotary disks. Adjustment of the head assemblies is accomplished by a differential screw which is readily accessible. Each head assembly 10 is supported by a mount structure 12 that is attached to a receiver 14. This is driven bidirectionally and radially relative to the storage disks by a linear drive motor. Initially, set screw 16 is turned to secure mount 12 in tight frictional relationship with receiver 14. To achieve a fine, vernier radial adjustment so that head assembly 10 is accurately positioned relative to data tracks, differential screw 18 is rotated so that receiver pin block 20 and head mount pin block 22 are slowly moved, until assembly 10 is properly aligned.

Head Adjustment Tool

In a random access disk storage system, a multiplicity of magnetic head assemblies must be precisely aligned radially relative to a stack of concentric rotary disks. Adjustment of the head assemblies is accomplished by a differential screw which is readily accessible. Each head assembly 10 is supported by a mount structure 12 that is attached to a receiver 14. This is driven bidirectionally and radially relative to the storage disks by a linear drive motor. Initially, set screw 16 is turned to secure mount 12 in tight frictional relationship with receiver
14. To achieve a fine, vernier radial adjustment so that head assembly 10 is accurately positioned relative to data tracks, differential screw 18 is rotated so that receiver pin block 20 and head mount pin block 22 are slowly moved, until assembly 10 is properly aligned. The use of the one accessible differential screw to align all the head assemblies mounted to the same receiver simplifies adjustment and provides more space.
