ABSTRACT:
A positioning apparatus, and associated method, for laterally positioning the head/access arms of a computer mass storage device disk drive relative to the individual storage media disks thereof. The relative lateral positions of the head/access arms and the corresponding disks are determined, and the access arms are laterally translated to permit a merging operation of the various head/access arms and disks of a disk stack to be performed. The head/access arms are positioned by the application of biasing forces which are normal to the longitudinal axes of the access arms to laterally position the access arms without sliding engagement between the positioning apparatus and the access arms.
