A new model for the signal dependent transition noise and partial erasure which occur in the
readback signal from thin film recording media is reviewed. This model, which is referred to …

A new model, called the MicroTrack Model, has been developed for signal dependent
transition noise and partial erasure that occurs in the readback signal from thin film magnetic …

The problem of noise in thin-film longitudinal media is analyzed experimentally and
theoretically. The physical mechanism for the noise is shown to be fluctuations in the …

A simple but accurate expression for general non-stationary noise correlation in the
presence of a recorded transition is analyzed in terms of both noise voltage and spectral …

A magnetic recording channel can be regarded as a “partial-response” channel because of
its inherent differentiation in the readback process. The conventional NRZI method of …

High density disk drive systems utilize fine grain polycrystalline thin films as storage
medium. These films exhibit noise that is pattern dependent and has appreciable magnitude …

The extracted dipulse technique, or pseudorandom sequence method, provides a means for
the characterization and measurement of a variety of linear and nonlinear recording effects …

This paper presents a model that includes both signal dependent and signal independent
noises. A method for extracting statistics of the coefficients of the noise expansion from …

A formalism is presented which relates the intrinsic error rate of a digital recording channel
to measurable channel parameters: interpulse interactions and signal-to-noise ratio …

General noise voltage relations based on magnetization correlations in thin film recording
media have been developed. Transition position jitter or amplitude fluctuations are a …
