| Abstract(in English) | Basing on the commercial software JMAG-Studio, we have developed a program in which the magnetization of magnetic particles is introduced into calculations of magnetization distributions in a recording layer, to three dimensionally analyze perpendicular magnetic recording mechanisms. Because this program was based on a FEM calculation, the head and media interactions and demagnetization during the recording process can be accurately modeled. Using this program, methods to reduce the recorded track width in perpendicular magnetic recording were investigated. Decreasing the magnetic spacing, the use of a side shielded head structure and using media with some extent exchange coupling are effective ways to reduce the track width in a single pole head and double layer perpendicular media recording system. |
