ABSTRACT:
A disk drive is provided in which the arm/head structures of the armstack are mounted in circumferentially spaced pairs, on individual projections of a rotatable actuator. The mounted pairs of arm/head structures project between the confronting disk surfaces of adjacent disks with the heads displaced from one another in a direction longitudinally of the arms and with the active faces of the heads pointing in opposite directions and in confronting or yielding contact with an adjacent disk surface. The magnetic heads are at different radial locations on respective confronting surfaces of adjacent disks of the disk stack as the actuator rotates, in all radial track positions except one track position.
