Patent ID: 7492545

Claim:
A servo controller (SC) system used in embedded disk controller, the SC system comprising: a servo timing controller, wherein the servo timing controller includes: a first register that stores measured servo-to-servo skew values that are used for time base adjustment at a given time to adjust for angular distance variance in servo fields from one memory storage device platter surface to another memory storage device platter surface; a first set of registers that receive stored servo-to-servo skew values and later measured servo-to-servo skew values; a logic device that receives a selected one of the stored and later measured servo-to-servo skew values from the first set of registers, that receives an adjustment value, and that one of increases and decreases the selected one of the servo-to-servo skew values by the adjustment value to determine an adjusted servo-to-servo skew value; and a servo field timer that increments a timer value between consecutive servo fields, receives the adjusted servo-to-servo skew value, and adjusts the incremented timer value between the consecutive servo fields based on the adjusted servo-to-servo skew value.
