ABSTRACT:
An apparatus and method for recording servo information on a data storage disk disposed within a enclosed data storage system housing. A small access aperture is provided on the housing proximate the pivot axis of a rotatably mounted actuator which permits access to the actuator through the housing. A unique coupling apparatus is installed on or, alternatively, fashioned as an integral part of the actuator to facilitate engagement with a precision pivot assembly of a servo writer at a plurality of engagement locations around the actuator pivot axis. Undesirable residual positional movement of the actuator and transducers during the servo writing procedure associated with shifting or settling of bearings disposed in a bearing cartridge of the actuator rotation assembly is significantly reduced or virtually eliminated by the equal distribution and passivation of torquing forces around the actuator pivot axis.
