20080220290 | Magnetic recording medium and manufacturing method for the same - To provide a magnetic recording medium manufacturing method capable of transferring a pattern that can serve as a source for forming anodized alumina-nanoholes with high precision and realizing high productivity, and a large-capacity magnetic recording medium capable of achieving high density recording. The method includes forming a metallic layer on a concavo-convex pattern formed on a surface of a mold; bonding a substrate using an adhesive to a surface of the metallic layer on the side opposite to the mold; separating the mold from the metallic layer; forming, through nanohole formation treatment, a porous layer in which a plurality of nanoholes are formed to orient in a direction substantially perpendicular to a substrate plane by using as a nanohole source a concavo-convex pattern which has been formed by transferring the concavo-convex pattern in the mold to the metallic layer; and charging a magnetic material inside the nanoholes. | 09-11-2008 |
20080226946 | Magnetic disc, stamper for making magnetic disc, and method for making magnetic disc - A magnetic disc has a data area including a magnetic data zone and nonmagnetic portions for physically separating the magnetic data zone, and also has a servo area provided with a magnetic pattern made up of magnetic portions and nonmagnetic portions. The servo area includes a belt-like area elongated in a radial direction of the magnetic disc and having a circumferential length at least twice as long as a unit length readable by a magnetic head in a circumferential direction of the magnetic disc. The belt-like area is provided with magnetic regions and nonmagnetic regions alternating with each other in the radial direction of the disc, where each of the magnetic and nonmagnetic regions extends from the first end to the second end of the belt-like area that are spaced from each other in the circumferential direction of the disc. | 09-18-2008 |
20120140319 | PROJECTOR SYSTEM AND DEVICE, RECORDING MEDIUM STORING POSITION DETECTION PROGRAM, AND IMAGE PROVIDING METHOD - A projector device includes an acquisition unit configured to acquire an image from an image pickup unit that picks up the image on a projection side of a transmissive type screen to which a display image is projected by a projector; a detection unit configured to detect a position where a luminance is changed on the acquired image; and an output unit configured to output the position on the acquired image where the change in luminance is detected. | 06-07-2012 |
