    摘要： Methods for forming write heads. One method includes forming a mask layer above a pole tip layer; forming a layer of resist above the mask layer; patterning the resist; removing portions of the mask layer not covered by the patterned resist; shaping a pole tip from the pole tip layer; depositing a layer of dielectric material above the pole tip and flux shaping layer, wherein the layer of dielectric material extends about adjacent to the mask layer; depositing a stop layer over the dielectric material, the stop layer abutting the mask layer; and polishing for forming a substantially planar upper surface comprising the mask layer and stop layer. Another method includes depositing a layer of dielectric material at least adjacent the pole tip, wherein the layer of dielectric material extends about adjacent to the mask layer. A further method includes forming dishing in the pole tip.

    摘要： The structure for a closely spaced, coplanar tape head array is disclosed. Narrow pitch is obtained by utilizing an overlapping coil structure, wherein write coils of adjacent heads overlap. The overlap is made possible by placing coils of adjacent heads at different levels within the thin film structure, separated by dielectric insulating layers.

    摘要： A slider fabrication assembly and method for making the same are provided. A slider is formed on a substrate. A corrodible component of the slider is exposed to an environment in contact with the slider. A kerf region of the substrate is positioned adjacent to the slider. The kerf region is removable from the slider. A sacrificial anode is embedded in the kerf region and exposed to the environment. The sacrificial anode is electrically coupled to the corrodible component of the slider thereby forming an electrochemical cell. The sacrificial anode is less noble, i.e., more corrodible, than the corrodible slider component, and thus corrodes first. When the kerf region is removed, the corroded sacrificial anode is removed as well.

    摘要翻译： 提供了一种滑块制造组件及其制造方法。 滑块形成在基板上。 滑块的可腐蚀部件暴露于与滑块接触的环境中。 衬底的切口区域邻近滑块定位。 切口区域可从滑块移除。 牺牲阳极嵌入切口区域并暴露于环境中。 牺牲阳极电耦合到滑块的可腐蚀部件，从而形成电化学电池。 牺牲阳极比可腐蚀的滑块部件更不贵，即更可腐蚀，因此首先腐蚀。 当切除切口区域时，腐蚀的牺牲阳极也被去除。

    摘要： A magnetic head having an air bearing surface (ABS) and a first pole tip. A second pole tip is spaced apart from and facing the upper end of the first pole tip across a write gap. A bump extends into a portion of the upper end of the first pole tip and a portion of the bottom end of the second pole tip, the bump being positioned away from the ABS. The bump defines a throat height of the first and second pole tips.

    摘要： An low profile inductive write head is provided to improve track definition and head efficiency and to reduce overcoat and pole tip protrusion and cracking caused by thermal expansion. A first insulation layer of an insulation stack enclosing the coil layer is formed of an non-magnetic inorganic insulator material such as aluminum oxide, silicon dioxide or titanium dioxide having a thickness of in the range of 0.2-0.3 microns. The thinner first insulation layer results in a significantly reduced slope of the insulation stack which decreases reflective notching during processing of the second pole tip to improve track definition. Improved thermal conduction properties of the inorganic insulator material improves heat sinking of the write coil reducing overcoat and pole tip protrusion and cracking at the pole tip/write gap layer interface.

    摘要： The thin film magnetic head of the present invention includes an improved P2 pole tip/yoke interface structure. The interface structure includes yoke material that is formed in a concave curved shape at the interface between the P2 pole tip and the yoke, such that a right angle interface between the P2 pole tip and the yoke is eliminated. The process for forming the P2 pole tip/yoke interface includes a second CMP polishing step that is performed on the surface of the write head wafer subsequent to the plating of the P2 pole tip thereon, and subsequent to a first CMP step. This second CMP step utilizes a relatively soft polishing pad and an acidic polishing slurry having a pH within the range of approximately 1 to approximately 5, and preferably approximately 2.5. The acidic polishing slurry contains a chemical agent which preferentially attacks the P2 pole tip material, such that the second CMP step results in the recession of the upper surface of the P2 pole tip relative to the dielectric layer surrounding it, as well as the significant rounding of the upper edges of the dielectric trench in which the P2 pole tip is formed. Thereafter, when the yoke is plated onto the P2 pole tip the rounded upper edges of the dielectric trench result in a concave curved interface between the yoke and the P2 pole tip. The resulting P2 pole tip/yoke interface possesses improved magnetic flux flow control properties and results in decreased side writing. Greater track per inch areal data storage results from the reduced side writing of the improved write head.
