    摘要： Embodiments of the invention reduce the throat height of a single pole type head with high accuracy. In one embodiment, a head with an electro lapping guide for controlling a write head's throat height during air bearing surface processing is made. Air bearing surface processing is performed using the electro lapping guide. For a read head, processing is performed using the read head itself or an electro lapping guide for the read head so that both the throat height of write head and the element height of read head are controlled.

    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： 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： Embodiments of the invention provide a thin film magnetic recording head that can reduce the round portion of the track restriction part of the main pole and has excellent track width accuracy, as well as its fabrication method. In one embodiment, the main pole is etched in the following three processes. (1) An ion beam is injected into the substrate at an angle of about 50°±20° while vibrating the substrate horizontally within a range of about ±(30° to 150°) in a reference direction in which the ion beam is oriented from the medium to the air bearing surface. (2) The ion beam is injected into the substrate at an angle of about 60°±20° while vibrating the substrate around a predetermined angle of about 90° to 135° from a direction in which the ion beam is oriented from the medium to the air bearing surface. (3) The ion beam is injected into the substrate at an angle of about 60°±20° while vibrating the substrate horizontally at a predetermined angle within about ±45° around a predetermined angle within about −90° to −135° from a direction in which the ion beam is oriented from the medium to the air bearing surface.
