20100254231 | OPTICAL DISK DEVICE - An optical disc apparatus according to the present invention includes: a laser light source for emitting multiple light beams, of which the wavelengths are different from each other and include a first wavelength and a second wavelength that is longer than the first wavelength; an optical system for converging an arbitrarily selected one of the light beams on an optical disc that has a surface and at least one information storage layer; a focus control section for controlling the focus position of the light beam with respect to the optical disc; and a defect detecting section, which senses light reflected from the surface of the optical disc with the focus position of the light beam set on the surface, thereby determining, based on the intensity of the reflected light, whether or not there is a fingerprint on the optical disc. | 10-07-2010 |
20110080814 | OPTICAL DISC APPARATUS AND METHOD OF MAKING LAYER-TO-LAYER JUMP IN MULTILAYER OPTICAL DISC - A layer-to-layer jumping method according to the present invention includes, after a layer-to-layer jump has been started in a multilayer optical disc, the step ST | 04-07-2011 |
20110137965 | FILE SYSTEM MANAGING METHOD AND RECORDING MEDIUM - In a recording medium including stacked recording layers, management data requiring reliability is recorded in the recording layer far from the surface of the recording medium and data bodies are recorded in the recording layer close to the surface of the recording medium. Thus a data file can be read even if defects such as fingerprints and scratches occur on the surface of the recording medium. | 06-09-2011 |
20110292779 | METHOD FOR IDENTIFYING GROUP OF MULTILAYER DISC, AND OPTICAL DISC DEVICE - The present invention provides a method for determining what group a given multilayer optical disc belongs to. The disc is one of a number of multilayer optical discs, which are designed so that information stored is retrievable from any of the discs by irradiating the disc with a light beam having the same wavelength and which have been classified into multiple groups. According to this method, performed first is Step (A) of measuring either a distance from a first one of multiple information layers of the given multilayer optical disc to a second one thereof, which is located adjacent to the first information layer, or a distance from the first information layer to the surface of the optical disc. Next, Step (B) of determining, by the distance measured, what group the given multilayer optical disc belongs to is performed. | 12-01-2011 |

20100002289 | MICROSCOPE OPTICAL SYSTEM, MICROSCOPE, AND VIRTUAL SLIDE FORMING SYSTEM - The purpose is to move an observation field of view of a microscope without moving or changing an objective lens without varying position or state of a sample. A microscope optical system according to the present invention has a mirror that changes the direction of the optical path by reflection and locates in the optical path between an objective lens of the microscope and an image to be observed. The mirror is able to be tilted with changing the position of a reflecting surface of the mirror. Accordingly, the observation field of view is moved by tilting the mirror. In other words, the observation field of view can be moved without changing positional relation between the objective lens of the microscope and the sample. | 01-07-2010 |
