摘要: A rotating magnetic memory, such as a disk drive using sector servo information, is initialized with servo information by first using the dedicated product head assembly, including transducers and the mounting and accessing mechanisms associated therewith, to write on the innermost and outermost data tracks, following which the tracks written by each transducer are read using a precision servowriter mechanism which is then positioned to duplicate the access path of the product head assembly and determine the position of such innermost and outermost tracks. By then offsetting the precision servowriter by a half track pitch and writing the servo information to form equally spaced tracks, the disk is initialized with full track pitch servo information which is positioned and aligned with the position and alignment of the dedicated product head assembly.
