Characteristics of thermally assisted magnetic recording

Abstract

Extensive thermally assisted recording measurements were performed on isotropic longitudinal media. The dynamic coercivity decrease provided by thermal assistance was quantified by spin stand measurements. Thermally assisted recording performance was found to equal the performance of conventional (nonthermally assisted) recording at significantly reduced values of write current. This reduction in write current is consistent with the coercivity decrease that occurs during the thermally assisted writing process.
