Abstract
A hard disk drive system includes a control module that generates a phase offset signal for a repeatable run out (RRO) field of a servo wedge based on an RRO phase of the RRO field and a data phase of data in at least one other servo wedge field of a previously written wedge. A read/write channel module adjusts a clock phase based on the phase offset signal.
