II. Physical Sources of Medium Noise

Abstract

Abstract-- A physically based model for a magnetic recording medium is augmented by the simulation of reading with a standard head model. The medium noise generated by this model comprises a repeatable component and a non-repeatable component. The repeatable component of medium noise is partially statistically characterized. The non-repeatable component of medium noise is shown to depend on the intrinsic properties of the recording medium in a manner consistent with the medium's computed storage capacity bound
