摘要： A hard disk control system comprises a phase adjust module, an offset adjust module, and a read/write timing module. The phase adjust module generates a phase adjust signal based on a phase difference between a first repeatable run out (RRO) field and a servo wedge field. The offset adjust module outputs a position calibration pattern to a storage medium based on the phase adjust signal; receives at least a portion of the position calibration pattern from the storage medium; and determines an offset based on a comparison between the output position calibration pattern and the received portion of the position calibration pattern. The read/write timing module determines a position to write a second RRO field on the storage medium based on the offset.

摘要： A system including a read module, a clock generator module, and a write module. The read module generates read signals in response to reading servo spirals from a magnetic medium of a hard disk drive. The clock generator module generates a spiral clock based on the read signals, and generates, based on the spiral clock, (i) a first write clock and (ii) a second write clock. The spiral clock has a first frequency, the first write clock has a second frequency, and the second write clock has a third frequency. The write module is configured to (i) write a first servo wedge on a first zone of the magnetic medium of the hard disk drive based on the first write clock, and (ii) write a second servo wedge on a second zone of the magnetic medium of the hard disk drive based on the second write clock.

摘要： A hard disk controller (HDC) of a hard disk drive (HDD) includes a read module, a clock generator module, and a write module. The read module reads servo spirals from a magnetic medium of the HDD via a read head of the HDD and generates read signals. The clock generator module generates a spiral clock having a first frequency based on the read signals and generates based on the spiral clock R write clocks having R frequencies, respectively, that are different than the first frequency, where R is an integer greater than 1. The write module writes via a write head of the HDD a first servo wedge on a first one of R zones of the magnetic medium using a first one of the R write clocks and a second servo wedge on a second one of the R zones using a second one of the R write clocks.
