MAGNETIC RECORDING CHANNEL MODEL WITH INTERTRACK INTERFERENCE

We propose a magnetic recording channel model incorporating both old information (OI) present in the guard band and data from adjacent tracks. We model the side reading properties of the head using the reciprocity integral to compute the flux transition response. Using a result of Lindholm[1] to represent the field of an inductive head, we compute specific channel models for various values of misregistration. This channel model is useful for the design and evaluation of future detection algorithms. It can be easily extended to include the effects of media noise and pulse distortion. The inclusion of intertrack interference and OI in the model facilitates study of system performance vs. track density.
