Data from digital data storage media employing a multitrack storage format can be efficiently detected with reduced complexity by using a breadth-first search algorithm on a one-dimensional time-varying trellis representation of the multitrack channel response. In this letter, we analyze the resulting performance. We propose a two-dimensional minimum phase detector target response and verify its performance through bit-error-rate simulations.
