Abstract:

Multitrack detection for shingled magnetic recording (SMR) using a two-head array system is considered. The channel suffers from intersymbol interference (ISI) in the down-track direction and intertrack interference (ITI) in the crosstrack direction. We propose a practical multihead/multitrack detector that provides a low-complexity approach to adaptive estimation of time-varying ITI. The performance of the proposed detection algorithm is analyzed in terms of its minimum distance parameter, and simulation results show that the proposed detector offers a performance advantage in settings where complexity constraints limit the maximum-likelihood two-track detector to use a static ITI estimate.
