A thick media recording model for quantitative study of media with arbitrary easy axis orientations

摘要

This work gives details of a quantitative recording model for magnetic media with arbitrary easy axis orientations. The model uses an iterative analytical approach to study variations with depth into the media allowing the investigation of thick and multilayered media, thereby extending the work of Williams and Comstock which applied only to very thin media. Using typical values for the head and medium interface, the model presents quantitative accuracy when compared with experimental data in both the frequency and time domains for metal evaporated (ME) tapes while using the minimum number of adjustable parameters.
