- 論文の詳細を見る
Numerical analysis of a Co-Cr medium-ring type head system for perpendicular recording are performed using a two dimensional model with a finite element method. A new magnetization model of the Co-Cr medium is proposed, a columnar structure being taken into consideration. The medium is divided into elements for the calculation and an additional field, H_<ad>∝(M_<upper>+M_<lower>) is assumed to be applied from upper and lower elements within a column, where M is the magnetization of the element. The results of the simulation show that the interaction between elements plays an important role in the magnetization process of the Co-Cr medium.
