Due to bits being recorded at ultra-high density, a bit-patterned media recording (BPMR) system is faced with two-dimensional (2D) interference, namely inter-symbol interference (ISI) and inter-track interference (ITI), which degrades the overall performance of a recording system. One solution to avoid the 2D interference effect is to apply a modulation code to forbid some specific data patterns leading...
In bit patterned magnetic recording (BPMR), The two-dimensional (2D) interference composed of inter-symbol and inter-track interference is a major problem especially at high areal density (AD). One way to alleviate the destructive effect of 2D interference is to deploy a 2D coding scheme on an input data sequence before recording in order to avoid some data patterns that easily cause an error at the...
In bit-patterned magnetic recording (BPMR), inter-symbol interference (ISI) and inter-track interference (ITI) become a major impairment due to small bit and track pitches. One way to alleviate ISI and ITI is to encode the data sequence before recording. In general, two-dimensional (2D) coding scheme requires many redundant bits, thus lowering the code rate. This paper proposes a novel 2D coding scheme...
