Abstract :
Write errors in bit-patterned-media-recording are a unique problem that may require nonconventional coding and signal processing techniques. Development of such advanced algorithms requires a simple yet accurate channel model to start with. In this paper, we analyze the various sources of write error in BPMR based hard drives and conduct write error characterization. The system parameters are either measured from current hard drives or set with realistic assumptions. A position dependent write error model is proposed based on these analyses which lead to a modified binary symmetric channel model for BPMR.
