摘要： Recording heads having an ESD shunt trace and methods of fabricating the same are disclosed. A recording head of the invention includes a first shield, a second shield, an MR read element between the first shield and the second shield, and an ESD shunt trace. The ESD shunt trace is formed from MR layers and is connected to the MR read element and one or both of the first shield and the second shield. One or more of the MR layers forming the ESD shunt trace are processed to reduce the MR properties of the ESD shunt trace. Examples of processing the ESD shunt trace are ion milling, ion implantation, oxidizing, reactive ion etching, sputter etching, wet chemical etching, etc.

摘要： Magnetic recording heads and associated fabrication methods are disclosed. A heat spreader structure in a magnetic recording head includes a seed layer with a heat spreader layer formed on the seed layer. When the heat spreader layer (e.g., Aluminum Nitride) is grown on the seed layer (e.g., NiTa or Alumina), the heat spreader layer forms a well-oriented crystalline structure that allows for a desired thermal conductivity, such as a thermal conductivity greater than about 55 W/m-K. As a result of using the seed layer, a material such as Aluminum Nitride can be used for a heat spreader layer to effectively dissipate heat in a magnetic recording head.

摘要： An article is formed as a substrate having a projection extending outwardly therefrom. The article may be a magnetic recording head and the projection a write pole. The projection has a width in a thinnest dimension measured parallel to a substrate surface of no more than about 0.3 micrometers and a height measured perpendicular to the substrate of not less than about 5 times the width. The article is fabricated by forming an overlying structure on the substrate with an edge thereon, depositing a replication layer lying on the edge, depositing a filler onto the edge and the substrate, so that the filler, the replication layer, and the overlying structure in combination comprise a continuous layer on the substrate, selectively removing at least a portion of the replication layer from a free surface of the continuous layer inwardly toward the substrate, to form a defined cavity, and depositing a projection material into the defined cavity to form the projection.
