Abstract

Bit-patterned media recording (BPMR) is a feasible technology to increase an areal density of hard disk drives. In practice, the insertion and deletion (Ins/Del) error is one of major problems in BPMR systems. This Ins/Del error arises from a write synchronization error, which may lead to an error burst at data detection process. In this paper, we propose a method to mitigate an Ins/Del error for BPMR systems, which uses a trellis-based detection technique together with the Varshamov and Tenengolts (VT) code to correct the Ins/Del error. We compare the performance of different methods in BPMR systems. Simulation results indicate that the proposed method can enhance the system performance in the presence of Ins/Del error. In addition, the proposed method is also robust to the change in the probability of Ins/Del occurrence.
