摘要： A thin film magnetic head is fabricated with a yoke structure, including P1 and P2 magnetic layers, having a width in the range of about 5 to 58 microns, preferably about 30 microns. The very narrow width minimizes popcorn noise, improves high frequency response and affords increased head circuit efficiency.

摘要： A tripad air bearing slider useful in a disk drive is designed with two outer pads that extend from two or more tapered sections at the leading edge of the slider towards the trailing edge. The pads are configured and angled so that a desired lift force is obtained that acts in opposition to a force provided by a spring loaded flexure or load beam. The angles that define the shape of the three pads are formed by simple mechanical cutting, using a diamond cutting wheel, for example, or alternatively by ion milling or reactive ion etching.

摘要： A thin film magnetic head is fabricated with a multiplicity of magnetic yokes (10,12,14,16) that interact effectively with an electrical coil (18). The magnetic P1 and P2 pole sections of the yoke are very narrow and form closely spaced envelopes about the coil. The multiple yokes are inductively linked to the coil so as to provide an increased number of flux interactions for a given length of coil turn. With this magnetic head design, signal output is increased, thermal noise is reduced, and the signal-to-noise ratio is effectively improved.
摘要翻译： 薄膜磁头由多个与电线圈（18）有效相互作用的磁轭（10,12,14,16）制成。 磁轭的P1和P2磁极部分很窄，并且在线圈周围形成紧密间隔的包络。 多个磁轭与线圈感应连接，以便为给定长度的线圈匝数提供增加数量的磁通量相互作用。 采用这种磁头设计，信号输出增加，热噪声降低，信噪比得到有效改善。
