摘要： A method of manufacturing a perpendicular magnetic write head capable of precisely narrowing a side gap is provided. A tip portion having a cross sectional geometry of an inverted trapezoid is formed in an opening portion of a non-magnetic layer and thereafter, the non-magnetic layer is etched with the tip portion as a mask. Thereby, a portion adjacent to the tip portion in a writing track width direction remains and an outermost edge portion of the tip portion in that direction is located on a plane which coincides with an etching face (side face) of the non-magnetic layer. When a gap layer is formed with a vapor phase growth such as a sputtering method to cover the side face of the non-magnetic layer and thereafter a side shield layer is formed adjacently to the tip portion therethrough, a thickness of the gap layer becomes extremely thin and is reproduced precisely. Therefore, the side gap is narrowed with high precision.

摘要： The invention provides a thin film magnetic head including a first pole portion having depressed portion that is formed therein. The depressed portion descends, backward within the first pole portion, at a first inclination angle &thgr;1 from a first inclination starting point P1. Then, an insulating film is filled up in the depressed portion so that it can be located up to the upper side of the surface of the first pole and have an inclined surface in the side of a medium opposing surface. Additionally, a first magnetic film of a second pole portion can have a larger saturated magnetic flux density than a second magnetic film of the second pole portion, and can include an inclined portion with a second inclination angle &thgr;2 from a second inclination starting point P2.

摘要： A perpendicular magnetic write head capable of suppressing damage and corrosion of a magnetic pole to secure a stable writing performance is provided. A non-magnetic protruding layer protruding from a main magnetic pole layer (tip portion) toward an air bearing surface side is formed on both sides of the tip portion in a writing track width direction. The non-magnetic protruding layer is located closer to a recording medium than the tip portion during writing operation, and is more likely to be in contact with the writing medium instead of the tip portion. Since the protective film portion covering the tip portion hardly peels off (e.g., compared to the protective film portion covering the non-magnetic protruding layer), the tip portion is hardly damaged or corroded. Since the tip portion is protected physically and chemically by the non-magnetic protruding layer, deterioration of the soft magnetic characteristics of the tip portion is suppressed.
摘要翻译：提供了能够抑制磁极的损坏和腐蚀以确保稳定的写入性能的垂直磁性写入头。从主磁极层（前端部）向空气轴承面侧突出的非磁性突出层形成在磁头部的书写轨道宽度方向的两侧。在写入操作期间，非磁性突出层位于比尖端部分更靠近记录介质的位置，并且更可能与书写介质接触而不是尖端部分。由于覆盖尖端部分的保护膜部分几乎不剥离（例如，与覆盖非磁性突出层的保护膜部分相比），尖端部分几乎不被损坏或腐蚀。由于尖端部分被非磁性突出层物理和化学地保护，所以抑制了尖端部分的软磁特性的劣化。

摘要： A perpendicular magnetic write head in which unintended erasure of information at the time of non-writing can be suppressed while keeping the capability of writing is provided. The perpendicular magnetic write head includes a magnetic pole tip portion, a first yoke portion connected to the magnetic pole tip portion, having a width larger than that of the magnetic pole tip portion, and having a recess portion in a center region thereof, and a second yoke portion embedded in the recess portion. The magnetic pole tip portion and the first yoke portion are integrally formed with a vapor deposition method, and the second yoke portion is formed with a plating method. Since the saturation flux density of the magnetic pole tip portion formed with the vapor deposition method becomes higher than that of the yoke portion, a magnetic flux intake capacity of the magnetic pole tip portion is ensured. In a magnetic domain structure of the yoke portion most of which is formed with the plating method, since an easy magnetization axis becomes likely to be directed in a direction perpendicular to an emitting direction of a magnetic flux, residual flux becomes less likely to leak out of the main magnetic pole layer at the time of non-writing.
摘要翻译：提供了在保持写入能力的同时抑制在非写入时的意外擦除信息的垂直磁性写入头。垂直磁性写入头包括磁极尖端部分，连接到磁极尖端部分的第一磁轭部分，其宽度大于磁极尖端部分的宽度，并且在其中心区域具有凹部，第二轭部嵌入凹部。磁极端部和第一磁轭部用气相沉积法一体形成，第二磁轭部形成电镀法。由于利用气相沉积法形成的磁极尖端部分的饱和磁通密度变得高于磁轭部分的饱和磁通密度，所以确保了磁极尖端部分的磁通量进入容量。在磁轭部分的磁畴结构中，其大部分由电镀法形成，由于容易的磁化轴变得可能沿垂直于磁通的发射方向的方向指向，所以残余磁通不太可能泄漏在非写入时的主磁极层。
