Abstract
A system includes a preamble determination module configured to determine an expected preamble of a target track. The expected preamble includes an associated timing recovery pattern. A filter module is configured to receive a readback signal read from the target track based on the expected preamble, and selectively filter the readback signal to remove inter track interference from the readback signal based on the expected preamble.
