Abstract

For pt. I. see O´Sullivan et al (Proc. 30th Allerton Conf. on Comm., Cont. and Comp., pp. 792-798, 1992). 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
