ABSTRACT:
A method of writing spiral servo tracks to a disk of a disk drive is disclosed. The disk is heated by applying a heating power to a heater for a time interval. After the time interval, the heating power is reduced, and the spiral servo tracks are written to the disk. In one embodiment, an external spiral servo writer comprises a heat lamp for heating an exterior surface of a head disk assembly (HDA) prior to writing spiral servo tracks to the disk.
