摘要： To protect the MR read head element from ESD damage during wafer level manufacturing, a lead from the MR element is electrically connected to one or both of the read head element shields during manufacturing. In a preferred embodiment of the present invention, the electrical connection is fabricated in the kerf area between adjacent magnetic heads as they are fabricated upon a wafer substrate. Thereafter, when the magnetic heads are separated by saw cutting through the kerf areas, the electrical connections are thereby removed, such that the MR element electrical leads and the shields are electrically isolated. In an alternative embodiment, one or more of the shields, as well as the MR element leads can also be electrically connected to the substrate upon which the magnetic head is fabricated. In further alternative embodiments, the electrical connection between one or more of the shields and the MR element electrical lead can be fabricated within the magnetic head area, rather than in the kerf area, and a suitable resistance is fabricated into the interconnecting circuit. In this embodiment, the electrical interconnection between the MR element electrical lead and one or more of the shields has a pre-designed electrical resistance and it remains in the magnetic head following fabrication.
摘要翻译：为了在晶片级制造期间保护MR读取头元件免受ESD损坏，来自MR元件的引线在制造期间电连接到读头元件屏蔽中的一个或两个。在本发明的优选实施例中，当在晶片衬底上制造时，在相邻磁头之间的切口区域中制造电连接。此后，当通过锯切通过切口区域分离磁头时，由此去除电连接，使得MR元件电引线和屏蔽件电隔离。在替代实施例中，一个或多个屏蔽件以及MR元件引线也可以电连接到其上制造磁头的基板。在另外的替代实施例中，一个或多个屏蔽件和MR元件电引线之间的电连接可以制造在磁头区域内，而不是在切口区域中，并且在互连电路中制造合适的电阻。在该实施例中，MR元件电引线与一个或多个屏蔽之间的电互连具有预先设计的电阻，并且在制造之后它保持在磁头中。

摘要： According to the present grinding method, a plurality of optical markers are formed by photolithography such that the markers are embedded in a chiplet having a magnetic head. Markers are preferably in the shape of a bar having predetermined height, width and length and are spaced from each other by a predetermined distance where one end of the bars are sequentially offset from each other by a predetermined amount. During coarse grinding of the magnetic head as the magnetic head surface material is ground away, the end-face of the bars, one at a time, become visible. The closer the grinding surface approaches the desired inductive throat or MR element height, more end-faces become visible. Coarse grinding continues until a predetermined number of end-faces become visible at which point the grinding process is terminated and the magnetic head is ready for the final lapping process.

摘要： A write head for use in a magnetic disk drive and methods of manufacturing the same. When a non-magnetic reactive ion etching (RIE) stop layer is used in a damascene main pole fabrication process, the leading edge shield and the side shield have a magnetic separation. By replacing a non-magnetic RIE stop layer with a magnetic RIE stop layer, no removal of the RIE stop layer around the main pole is necessary. Additionally, the leading edge shield and the side shield will magnetically join together without extra processing as there will be no magnetic separation between the leading edge shield and the side shield.

摘要： A slider structure that allows a grounded heater element to be employed, while also allowing a decision of whether the slider is to be an “up” slider or a “down” slider to be made in a late stage in the formation of the slider. The slider includes electrical contact pads for making electrical connection with the heater element. The slider also includes a dedicated ground path formed on the slider body at a location that is removed from either of the first and second contact pads, ground path providing electrical connectivity to the slider body. At a late stage in the manufacture of the read and write head, a determination can be made as to which contact pad is to be a ground pad, and that pad can be electrically connected with the ground path.
