Abstract
A read/write channel module including a sampling module configured to sample a read signal corresponding to data stored on a disk. A first preamble is encoded with a first timing recovery pattern on a first track of the disk. The first timing recovery pattern includes a first pattern that changes every x bits. A second preamble is encoded with a second timing recovery pattern on a second track of the disk adjacent to the first track. The second timing recovery pattern includes a second pattern that changes every y bits. A data processing module is configured to process the read signal to remove inter track interference from the read signal based on a difference between the first timing recovery pattern and the second timing recovery pattern.
