ABSTRACT:
User data is read from a medium having servo data and user data encoded thereon. The user data is read with a read/write head that is operable in a write mode and a read mode. Servo data is read in a time window following a transition from write mode to read mode, with a frequency passband that has a first low frequency corner. User data is read from the medium after expiration of the time window, with a frequency passband that has a second low frequency corner that is lower than the first low frequency corner.
