Abstract

A new read channel architecture achieving diversity effects for bit patterned magnetic recording is proposed in this paper. In the proposed channel architecture, a new channel model generating several different channels for the desired symbols and the diversity achieving detection schemes are proposed to obtain performance gains with a simple structure. By using the proposed channel model, M different channels for the M desired symbols can be generated from the M reading operations and then M different channels can be exploited to obtain spatial diversity gains with the diversity achieving detection schemes. For the diversity achieving detection schemes, a single-track interference cancellation scheme is proposed based on ordered successive interference cancellation algorithm. To consider interference from the side-tracks, a multi-track interference cancellation (MTIC) scheme is also proposed. Simulation results show that the MTIC scheme with a simpler structure yields more than 1.5 dB gains over the conventional schemes when an areal density is 3 Tb/in2.
