  Abstract

Bit-patterned media recording (BPMR) is a potential future technology to record data in magnetic islands (one bit per island). In BPMR systems, to increase the areal density, the distance between adjacent islands must be reduced. Since leading to two-dimensional (2D) interference increased significantly. The bit error rates performance of BPMR systems is seriously decreased due to the emergence of 2D interference. This paper presents an error-correcting 7/10 modulation code. This modulation converts 7-bit data to 10-bit group symbols. Each these symbol have two properties include avoid isolate inter-symbol interference between neighbor islands and archives minimum distance Hamming of 2. Besides, we designed this modulation code to fit into a staggered-array BPMR layout, which helps BPMR systems overcome the limits of the high areal density. The results of the simulation show that the BPMR system with the proposed modulation code better than the system without the modulation code.
