Summary:
Various detection approaches were proposed to tackle 2-D interference in high density magnetic recording in the literature; however, most of them employed modified 1-D detectors, pseudo 2-D detectors extended from 1-D, instead of a full-fledged multi-track 2-D detection technique to avoid the high computational complexity. In this paper, firstly we study the performance of a full-fledged multi-track joint 2-D Viterbi detector exploiting multi-head array technology for bit patterned media recording (BPMR) system. Due to its high complexity, we also propose a simplified multi-track joint 2-D detector by doing a trade-off between complexity and performance gain. Finally, the performances of joint 2-D detectors are compared with that of conventional 2-D detection technique using multiple single-track detectors.
