| 20110025309 | ANGLE-OF-ROTATION SENSOR APPARATUS - The angle-of-rotation sensor apparatus of the invention comprises a shaft supported rotatably about an axial center, a permanent magnet fixed to one end face of the shaft, and a magnetic field sensor device located in opposition to the permanent magnet at a constant spacing. The permanent magnet used is in a cuboidal shape and magnetized in the minor axis (X) direction at the rectangular surface opposing to the magnetic field sensor device. The minor axis side is defined as the X direction and the major axis side as the Y direction. Given the opposing surface of the same area, the area where the angle distribution of the magnetic field emitted out of the permanent magnet can be placed in a uniform direction is made so wide that the tolerance range for axial alignment errors between the magnetic field sensor device and the permanent magnet can be enlarged. | 02-03-2011 |
| 20110024388 | METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM - A method for manufacturing a magnetic recording medium is provided which can sufficiently reduce variations in surface roughness even in the simultaneous presence of a region of a relatively wide concave and convex portion and a region of a relatively narrow concave and convex portion in the recording layer. The method includes the steps of etching a recording layer based on a (first) mask layer to process it in a concavo-convex pattern, and depositing a filler over the recording layer and the mask layer to fill a concave portion with the filler. In between those steps, provided is the step of removing part of the first mask layer over a recording element (a convex portion of the recording layer) by dry etching in which an etching rate for the mask layer is higher than that for the recording layer so that the mask layer remains over the recording element. | 02-03-2011 |
