Systems and methods for performing timing acquisition on an expected preamble of a read signal

摘要

A system including a read/write channel module and a data processing module. The read/write channel module is configured to sample a read signal corresponding to data read from a disk. The data processing module is configured to determine a first track of the disk. A first preamble of the first track is encoded to include a first timing recovery pattern, a second preamble of a second track of the disk is encoded to include a second timing recovery pattern, and a first period of the first timing recovery pattern is different than a second period of the second timing recovery pattern. The data processing module is further configured to determine an expected preamble and process the read signal to remove inter track interference from the read signal based on the expected preamble and an expected difference between the first period and the second period.
