The magnetic recording process has been simulated for normal particulate longitudinal media. The mechanism of record optimization as well as the effects of demagnetization fields, record spacing, and record gap have been investigated. Results are presented in terms of recording spectra and vector plots of the magnetization of an isolated transition. A method of examining magnetization patterns is presented that gives physical insight into the phenomena. Interference effects that lead to high- and low-current spectral nulls are explained
