Abstract
Apparatus and method for orienting a head over a disc within a multi-disc servo-track writer preferably uses two gas bearings, an adaptor plate, and an actuator assembly including an E-block and arm/head assembly. Rotation of the E-block, and hence actuator arm/head assembly, can be controlled by the movement of a rotational gas bearing, which is rotated by a motor. The gas bearing provides for reduced friction and, as a result, decreased eccentricity of the head as compared to related art configurations. A translational gas bearing can be used for laterally positioning the actuator assembly for servo track recording.
