Title: Optical information recording medium and method for manufacturing the same
Inventor: MIURA YUJI
IPC: G11B7/2433
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical information recording medium that an extremely thin crystallization promoting layer can be uniformly formed to specified film thickness with good reproducibility and that initialization is surely made unnecessary. SOLUTION: The crystallization promoting layer is formed by a method of collimate sputtering by using a collimate plate 11 so that the extremely thin crystallization promoting layer can be formed in a proper time because of its slow film forming rate. Thus, the extremely thin crystallization promoting layer can be uniformly formed to specified film thickness with good reproducibility, and initialization is surely made unnecessary in the manufactured optical information recording medium.

IPC: G01S17/88
Filed: 2000-05-01
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for inferring a target position capable of accurately inferring the position even without obtaining image information from a target. SOLUTION: A target direction inference arithmetic circuit 7 can infer the target position based on an acceleration and an angular speed detected by an inertial sensor 8 even without obtaining the image information from the target. Further, a distance to an article existing in a direction of the calculated target position is measured by a range finding unit 6, and the target position obtained by the calculation can be corrected based on the measured distance. Thus, whether the calculated result of the target position includes an error or not can be judged. When the result includes the error, the calculated target position is corrected based on the result to eliminate the error, or can be reduced. Thus, the target position can be accurately inferred even without image information from the target.
