- 論文の詳細を見る
We present a simple analysis for magnetic behaviors of exchange-coupled granular/continuous (CGC) perpendicular magnetic recording media. The analysis shows how the CGC media behave against a vertical external field. The slope of the magnetization curves is governed by the thickness ratio (γ) of a continuous layer t_c, to a granular layer t_g and the domain wall energy σ_w of the continuous layer. The size of a magnetization reversal unit which would dominate the recording resolution and thermal stability can be easily evaluated by the present analysis.
