Abstract:

A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.

A method for providing a structure in a magnetic transducer is described. The method includes performing a first planarization that exposes a top surface of the magnetic transducer. This first planarization also terminates before a portion of a first planarization buffer layer is removed. The method also includes providing a second planarization buffer layer after the first planarization is performed. The second planarization buffer layer is above the first planarization buffer layer. The method also includes performing a second planarization. This second planarization does not completely remove the second planarization buffer layer. The method also includes performing a third planarization terminating after the first planarization buffer layer is exposed and before the first planarization buffer layer is completely removed.

US Classification:

216 22, 216 66, 216 88, 216 89, 2504923
Abstract:

Methods of producing magnetic recording heads are disclosed. The methods can include providing a wafer comprising a substrate layer in which are disposed a plurality of damascene trenches. The method can further include depositing a pole material across the whole wafer, wherein the plurality of trenches are filled with the pole material. The methods can further include depositing a mask material over the pole material across the whole wafer. The methods can further include performing a first material removal process across the whole wafer to remove the mask material and a first portion of the pole material at a same material removal rate. The methods can further include performing a second material removal process to remove a second portion of the pole material above the substrate layer.

The magnetic structure has a desired thickness, a bevel, and a flare point a distance from the ABS. The method and system include providing at least three ELGs. A first ELG has first and second edges first and second distances from the ABS. A second ELG has third and fourth edges third and second distances from the ABS. A third ELG has fifth and sixth edges fourth and second distances from the ABS. The first, third, and fourth distances correspond to a stripe height and an offset. The first, third, and fourth distance and/or the second distance corresponds to an intersection between the bevel and the desired thickness. The method and system also include measuring resistances of the ELGs, and calibrating the ELG(s) utilizing the offset and resistances.
