  Abstract

To satisfy the demand for high areal density in bit-patterned media recording (BPMR) technology, which is a futuristic magnetics data storage system, the space between islands is reduced. However, this reduction causes intersymbol interference and intertrack interference, resulting in the corruption of data detection. In addition, because data storage systems encounter difficulty in retransmitting data unlike other communication systems, such systems require a low probability of decoding failure. In this paper, we compare the bit error rate performance of three types of low-density parity check (LDPC) coding structures for BPMR systems. To correct errors and improve the performance of data storage systems, LDPC codes with iterative decoding are used as an important technique. Using similar system structures and overall code rates, the three types of LDPC coding structures are simulated to verify performance.
