摘要

为了使磁记录的面密度达到1 Tbit/ In /sup / 2/,根据目前的技术,一个可行的系统将包括一个垂直的磁头和一个具有软磁底层的垂直介质。微磁建模在记录系统的设计和分析中起着重要的作用,在任何这样的计算中,有必要获得由磁头产生的磁场的准确数据。数值有限元和有限差分计算是计算密集型的,特别是在3D中,但是现在在考虑磁性底层的3D分析模型方面取得了进展。本文报道了这方面的进展,并特别考虑了双屏蔽垂直单极头的几何形状。

3-D head field modeling for perpendicular magnetic recording
In order to achieve areal densities in magnetic recording of the order of 1 Tbit/in/sup 2/ it has been suggested that a feasible system, based on current technologies, will involve a perpendicular head and a perpendicular medium with a soft magnetic underlayer. Micromagnetic modelling plays an important role in the design and analysis of recording systems and within any such calculation it is necessary to have accurate data on the magnetic field produced by the head. Numerical finite element and finite difference calculations are computationally intensive, particularly in 3D, but progress is now being made with 3D analytic models which take the magnetic underlayer into account. This paper reports on progress in that direction and in particular considers the geometry of a double-shielded perpendicular single pole head.
