摘要： A T-shaped pole tip portion of an upper pole of a write element for a magnetic disk drive is provided. One end of the pole tip portion, constituting the bottom of the “T,” forms a narrow nose segment at an air bearing surface, while a wing segment at the opposite end of the pole tip portion constitutes the cross-bar top of the “T.” A transition segment extends between the nose segment and the wing segment. A yoke portion of the upper pole includes a surface that is parallel to the air bearing surface and recessed therefrom by a P3R depth. The transition segment does not widen significantly until after the P3R depth, accordingly, the wing segment is recessed from the air bearing surface by more than the P3R depth.
摘要翻译：提供了用于磁盘驱动器的写入元件的上极的T形极尖部分。构成“T”底部的极端部的一端在空气轴承面形成窄的鼻部，而在极尖部的另一端的翼部构成“ T.“ 过渡段在鼻段和翼段之间延伸。上极的轭部包括平行于空气轴承表面并且通过P 3 R深度从其中凹入的表面。在P 3 R深度之后，过渡段不会显着扩大，因此翼段从空气轴承表面凹陷多于P 3 R深度。

摘要： A compound thin film magnetic head in which the upper shield of the readout MR head also serves as the lower magnetic film of the write inductive head. The upper shield has a layered structure including a shield part of soft magnetic material functioning as a shield to magnetically shield the MR head, a lower pole part and transition part of soft magnetic material functioning as a write magnetic pole opposing the upper pole of the inductive head, and a nonmagnetic separation layer to magnetically separate these. Between the lower pole part and the transition part, an additional nonmagnetic separation layer can be provided. The shield part can be configured from multiple magnetic films formed in layers and enclosing a nonmagnetic separation layer.

摘要： A composite type thin-film magnetic head. In one embodiment, a substrate is used as a base, and an insulating film, a lower shielding magnetic film, a magneto-resistive element, an upper shielding magnetic film, a magnetic gap film, a recording inductive magnetic film and a protective layer are laminated on this base. An inductive head used for recording is formed by the upper shielding magnetic film. A magnetic gap film, a recording inductive magnetic film, and a magneto-resistive head used for playback are formed by the magneto-resistive element. The upper shielding magnetic film and recording inductive magnetic film are formed by an electroplating of permalloy. The upper shielding magnetic film has a lower nickel concentration on the side of the magnetic gap film than on the side of the magneto-resistive element.
