【摘要】：提出了一种基于响应面的磁记录写场分析方法,该方法由基于有限元电磁场分析的参数化写头模型;基于有限差分法的磁性存储介质微磁模型;基于响应法的有效写场模型3个主要模块构成,并能够有效的分析写头几何结构与存储介质对有效写场梯度产生的综合影响。利用该方法,进一步分析了面向瓦片式磁记录的非对称式写头的几何设计参数与存储介质属性对有效写场梯度的影响。分析结果表明,在本办法涉及的写头设计参数中,主磁极尾部屏蔽间隙为主要影响参数,横向屏蔽间隙为次要影响参数。此外,磁性存储介质的各项异性能密度与写头几何参数会对有效写场梯度的影响有较强的交叉作用,从而说明了写头与存储介质作为整体进行设计的必要性。
[Abstract]:In this paper, a method of magnetic recording write field analysis based on response surface is proposed. The method consists of a parameterized write head model based on finite element electromagnetic field analysis and a magnetic storage medium micromagnetic model based on finite difference method.The effective write field model based on response method is composed of three main modules, and it can effectively analyze the comprehensive effects of the geometric structure of the write head and the storage medium on the effective write field gradient.By using this method, the effects of geometric design parameters and storage medium properties on the effective write field gradient of an asymmetric write head for tile magnetic recording are further analyzed.The results show that the shielding clearance at the tail of the main magnetic pole is the main influence parameter and the transverse shielding clearance is the secondary parameter among the design parameters of the write head involved in this method.In addition, the heterosexual energy density of magnetic storage medium and the geometric parameters of the write head have a strong cross effect on the effective write field gradient, which shows the necessity of the design of the write head and the memory medium as a whole.
