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.
A method of writing servo information to a data storage disk, disposed in an enclosed data storage system housing having a cover and a base, with a servo writer assembly having a pivot assembly, the data storage system having a transducer for transferring data to and from the disk and an actuator, having a central bore and rotatably mounted about a stationary actuator shaft mounted to the housing base, for moving the transducer across the disk, the method of writing servo information comprising the steps of:
