Abstract
The gyromagnetic switching process in longitudinal thin film recording media is studied by using numerical micromagnetics. The dynamic recor ding process of medium magnetization transition is examined in detail. The head field rise time required for the formation of a magnetizatio n transition is studied at different deep gap field magnitudes for med ia with damping constants ranging from 0.01 to 1.0. The gyromagnetic s witching limit on medium recording data rata is investigated for cases with various damping constants and record head held rise times.
