Patent number: 7760615Abstract: A rewritable phase-change optical recording medium is provided, which includes a substrate, a first information layer, a spacer layer, a second information layer, and a cover layer. The second information layer includes a recording film containing Sb as a main component and V or V and In as second components. When an amorphous mark formed in the recording film is irradiated with a reproduction beam, crystallization of the amorphous mark occurs only in a central portion in the width direction of the amorphous mark. The width direction is orthogonal to the scanning direction of the laser beam. The recording film is formed of a material that exhibits a change in degree of modulation of 5% or less when recorded information is repeatedly reproduced. The change in degree of modulation is a change from when the number of times of reproduction is 100,000 to when it is 400,000.Type: GrantFiled: June 12, 2008Date of Patent: July 20, 2010Assignee: TDK CorporationInventors: Hiroshi Shinngai, Hideki Hirata, Tatsuya Kato, Hiroshi Takasaki, Yasuhiro Takagi, Masaki Sobu, Masanori Kosuda

Patent number: 7719621Abstract: It is an object of the present invention to display unnaturalness-free images without showing an observer repetitive images in accordance with the observer's viewpoint. A light beam control element 101b limits a viewing area of images composed of light emitted from a light source array 101a. Here, a terminal position detection sensor 102 or an observer position detection sensor 103 detects a relative positional relationship between the observer's eye observing the image formed by the light emitted from the light source array 101a, and the light source array 101a and the light beam control element 101b. Based on the positional relationship detected by these sensors, a display image control device 104 controls the light source array 101a so as to change display contents of the light forming the image with the viewing area limited by the light beam control element 101b.Type: GrantFiled: July 3, 2007Date of Patent: May 18, 2010Assignee: NTT DoCoMo, Inc.Inventors: Masashi Tsuboi, Tsutomu Horikoshi, Mikiko Nakanishi, Yasuhiro Takagi

Publication number: 20080165642Abstract: In an evaluation device and an evaluation system, the level of base power is set higher than that in an optimal recording condition at a set room temperature and lower than the level of bias power. In particular, the level of the base power is set so that the jitter value of a recording mark and a blank, which is formed in a required high temperature environment, during reproduction in the high temperature environment becomes minimum. By evaluating the recording characteristic of a recording mark and a blank formed by irradiation of recording laser light in the form of a pulse train, the recording characteristic of an optical recording medium in high-speed recording in high temperature environment is evaluated.Type: ApplicationFiled: December 28, 2007Publication date: July 10, 2008Applicant: TDK CORPORATIONInventors: Tatsuya Kato, Yasuhiro Takagi, Hideki Hirata, Hajime Utsunomiya
