  Abstract

We present an asymmetric linear channel model for a perpendicular magnetic recording with a ring-head. The single-transition and impulse responses of the channel are represented by the superposition of Lorentzian pulses, and by dipulse type of two single-transition responses with asymmetric scale parameters, respectively. The impulse response is adjusted by preamplifier outputs of a practical perpendicular recording channel. We confirmed that the simulated waveforms and their spectra of the model are in good agreement with those of the real readback signals.
