Bit-patterned media is a novel technology for magnetic data storage that is poised to increase recording density beyond 1 Tb/sq. in. However, a significant concern in BPMR is the stringent requirements for synchronization between write clock and island position, errors in which may manifest as insertions and deletions. In this paper, we introduce a method for compensating for synchronization errors by using conventional error-correcting codes. We present a numerical study that provides bounds on achievable coding rates. We also perform a simulation study to demonstrate the applicability of the proposed scheme in practical systems.
