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.
