A fast microtrack simulator for high-density perpendicular recording

We present a fast waveform simulator based on the microtrack model for high-density perpendicular recording. The simulator characterizes dominant noise sources to create realistic recording outputs that allow useful evaluation of modern software channels. A novel model architecture was developed to overcome the computational burden due to the long perpendicular response. Speed and distortion tradeoffs are quantified and indicate that a throughput of 1 Mbps can be achieved with negligible distortion on a contemporary desktop computer.
