Method and apparatus for analysis of magnetic characteristics of magnetic device, magnetic head, and magnetic recording and reproducing apparatus

摘要

A method and apparatus for analysis of magnetic characteristics of a magnetic device used for designing a magnetic head. The magnetic head has recording and reproducing characteristics and a recording and reproducing apparatus of magnetic characteristics. The apparatus for analysis of magnetic characteristics includes a data input part, a coupled analysis part, and a result output part. The data input part is provided with data related to the characteristics of substances composing the magnetic device, data related to the magnetic device divided into a plurality of parts, data concerning the boundary conditions for analysis of the magnetic device, and data concerning the boundary conditions for analysis of the magnetic field. In the analysis part, a stress distribution for each of the plurality of parts divided on the basis of the data related to the boundary conditions input from the data input part is obtained, and magnetic characteristics for each of the plurality of parts based on the data concerning the boundary conditions of the magnetic field and the stress distribution of the magnetic device are obtained, and magnetic characteristics of the whole magnetic device are obtained based on the magnetic characteristics of each of the plurality of parts.
