Abstract
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 to severe 2D interference. Nonetheless, this method usually requires either many redundant bits or additional memory. Thus, this paper proposes a simple technique to encode an input data sequence to mitigate the 2D interference effect before recording them onto a magnetic medium. The proposed technique shows the improvement in reducing complexity and additional memory using a crossover-based technique when comparing to other existing methods.
