ABSTRACT:
A process for continually compensating for the microjog error resulting from RRO. Typically, the 1F RRO is the most significant, but the method could be applied to the microjog error caused by RRO of other frequencies. The process continually determines an instantaneous microjog error based on the RRO and adjusts the read element target position throughout one revolution, such that the write element remains centered on its intended position.
