摘要： Embodiments in accordance with the present invention relate to methods wherein when a main pole is processed by using an ion milling technique, a re-adhesion layer created on the side face of the resist mask is removed with certainty. In one embodiment, an inorganic insulator from 5 nm to 100 nm which is soluble in an alkaline is arranged between the main pole material and a mask for processing the main pole material, and the main pole is processed by ion milling. After this process, the mask is peeled off, a surface treatment is performed by using an alkaline solution, resulting in the re-deposition film being removed.

摘要： An optically assisted magnetic recording head causes light to be efficiently incident on a near-field light generating element and is thereby capable of efficiently generating near-field light. The optically assisted magnetic recording head, according to one embodiment, has a waveguide and a thin metal film. The waveguide has a core and a clad at least partially surrounding the core and serves as near-field light generating device. The core has a plate-shaped portion that has a small width and protrudes from an edge of the core. The edge of the core is located on the air bearing surface side. The thin metal film is provided on an upper portion and side portions of the plate-shaped portion to cover the edge of the core at the air bearing surface side. Other systems and methods are disclosed as well to achieve efficient incident light on a near-field light generating element.

摘要： If the length of a track-defining section from an air bearing surface varies due to tolerance during a head manufacturing process, the recording magnetic field changes, which involves the variation of the track width to be recorded on the medium. In accordance with an embodiment of the present invention, the main magnetic pole of a magnetic head includes a track-defining section shaped in trapezoid and a magnetic flux guiding section formed in trapezoid, as viewed from above. The track-defining section is formed such that its width parallel to the air bearing surface (ABS) increases at the rate of 10 to 20% with respect to its height-direction length. The rate of 10 to 20% is a range in which the shape is properly controllable taking into account the variations resulting from the tolerance of the head manufacturing process.
