Abstract
An electromagnetic read/write head carrier structure is disclosed which permits micro-positioning of the heads carried thereon. The carrier structure incorporates a movable subframe mounted in a floating, friction-free condition on the servo arm of a magnetic media drive. Micro-adjustments in head position for use with high-density data formats are accomplished by micro-positioning the head carrier subframe with respect to the servo arm. A voice coil motor is used to induce relative movement between the head carrier subframe and servo arm.
