摘要： A magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to be moved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head also includes a non-magnetic spacer layer formed over the magnetic shell structure and a trailing magnetic shield, a portion of which is formed over the non-magnetic spacer.

摘要： A method for self aligning a lapping guide with a structure of a write pole. A write pole is formed over a substrate and an electrically conductive material lapping guide material is deposited in a location that is removed from the write pole. A mask is then formed over a portion of the write pole and a portion of the electrically conductive material. A material removal process such as reactive ion etching can then be performed to remove a portion of the magnetic material that is not protected by the mask structure. An magnetic material is then electroplated over the write pole with the write pole, with the mask still in place. In this way, the electroplated material has an edge that is self aligned with an edge of the electrically conductive lapping guide material, both being defined by the same mask structure.

摘要： A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes the formation of a write pole over a substrate. A non-magnetic side gap layer is deposited and an ion milling is used to remove a portion of the substrate to lower the floor of the substrate. A sacrificial fill layer can then be deposited. A chemical mechanical polishing process can be used to remove the mask structure remaining as a remnant of the formation of the write pole, and then the sacrificial fill layer can be removed. A non-magnetic, electrically conductive material can be deposited to form a trailing gap, and a magnetic material can then be deposited to form a wrap around trailing shield.

摘要： A method for fabricating a magnetic head with a trapezoidal shaped pole piece tip is described. The body of the main pole piece is deposited; then one or more layers for the pole piece tip are deposited. A bed material is deposited over the pole piece tip material. A void is formed in the bed material over the area for the pole piece tip. The void is filled with an ion-milling resistant material such as alumina preferably using atomic layer deposition or atomic layer chemical vapor deposition. The excess ion-milling resistant material and the bed material are removed. The result is an ion-milling mask formed over the area for the pole piece tip. Ion milling is then used to remove the unmasked material in the pole piece tip layer and to form a beveled pole piece tip and preferably a beveled face on the main pole piece.

摘要： Heads for perpendicular recording using a floating-trailing shield as part of the magnetic circuit for writing magnetic domains in the recording media are described. The floating-trailing shield is separated from the main pole piece by a layer of non-magnetic material along its entire length and the air bearing surface of the floating-trailing shield is substantially larger than that of the main pole piece. The reluctance between the trailing shield and the underlayer in the recording medium is made so low that both are at the same magnetomotive force (or potential), so that no direct connection is needed between the floating-trailing shield and the yoke. When the head is used in a storage system with a magnetic recording medium with a soft underlayer, the floating-trailing shield is, in effect, magnetically shorted to the return pole piece during recording.

摘要： A mask structure for fabricating a write pole for a perpendicular write head. The mask structure includes a first and second hard mask structures separated by an image transfer layer, such as DURAMIDE®. The first mask structure may be a bi-layer mask structure that functions as a CMP stop as well as a hard mask for ion milling. The first hard mask is chosen to have a desired resistance to removal by ion milling to maintain excellent track width control during an ion milling process used to form the write pole. Therefore, the first hard mask may be comprises of two layers selected from the group consisting of Rh, alumina, and diamond like carbon (DLC). The second hard mask is constructed of a material that functions as a bottom antireflective coating as well as a hard mask.

摘要： The method of making a magnetic head assembly includes forming a second pole piece layer that is recessed from a head surface, forming a reactive ion etchable (RIEable) pole tip forming layer on the second pole piece layer, forming an adhesion/stop layer of tantalum (Ta) on the pole tip forming layer, forming a photoresist mask on the adhesion/stop layer with an opening for patterning the adhesion/stop layer and the pole tip forming layer with another opening, reactive ion etching (RIE) through the opening to form the other opening, forming the second pole piece pole tip in the other opening with a top which is above a top of the adhesion/stop layer and chemical mechanical polishing (CMP) the top of the second pole piece pole tip until the CMP contacts the adhesion/stop layer. The invention also includes the magnetic head made by such a process.

摘要： A bi-layer, floating, trailing shield for use in a perpendicular magnetic recording system and a method for manufacturing such a trailing shield. Manufacturing the trailing shield as a bilayer trailing shield allows certain critical alignments to be maintained during lithography and allows high resolution photolithographic procedures to be used by allowing the use of a thinner resist, especially during construction of the first layer of the bilayer trailing shield structure. A trailing shield according to an embodiment of the invention improves magnetic performance of the write head by canting the magnetic write field from the write pole.
