Patent ID: 8810938

Claim:
A system, comprising: a read/write channel module configured to sample a read signal corresponding to data read from a disk; and a data processing module configured to determine a first track of the disk that a read/write device is positioned over, wherein (i) a first preamble of the first track is encoded to include a first timing recovery pattern, (ii) a second preamble of a second track of the disk, adjacent to the first track, is encoded to include a second timing recovery pattern, and (iii) a first period associated with the first timing recovery pattern is twice or half of a second period associated with the second timing recovery pattern, determine an expected preamble of the first track, wherein the expected preamble corresponds to a preamble that is expected to be on the first track that the read/write device is positioned over, and process the read signal to remove inter track interference from the read signal based on (i) the expected preamble and (ii) an expected difference between the first period and the second period.
