9/12 Two-dimensional modulation code for bit-patterned media recording

Chi Dinh Nguyen, Jaejin Lee

Abstract

This paper presents a 9/12 two-dimensional (2D) modulation code as a way to overcome 2D intersymbol interference (ISI) in bit-patterned media recording (BPMR) systems. BPMR systems are regarded as one of the promising candidates for the attainment of areal density increases that are beyond the capacities of conventional storage systems. The 2D ISI problem significantly degrades the system performance. The results show that the proposed modulation code offers a gain of approximately 2 dB over that of a system without encoding.
