Abstract

We report the results of an investigation of bit-patterned media recording (BPMR) channels containing insertion/deletion errors that may be introduced because of the write synchronization problem. We first describe a simple channel model for insertion/deletion errors in BPM, as a result of write clock frequency offset. Based on this channel model, we propose a new error correction coding (ECC) scheme to correct insertion/deletion errors-picket shift. Simulation results show that picket shift performs significantly better than a no-ECC scheme in the presence of insertion/deletion errors.
