Abstract:
PROBLEM TO BE SOLVED: To acquire information about a user from a sensor device, and to analyze the acquired information, and to derive a specific conclusion, and to provide it to a user. SOLUTION: Image data acquired by a sensor device, for example, a camera device are transmitted together with a user ID to a server, and primary analysis processing is applied to the transmitted image data at a server device. In the primary analysis processing, predetermined processing is applied to the image data, and the image data are compared with reference information to be a reference. Threshold decision is made to the result of the primary analysis processing, and when it is decided that the result of the primary analytic processing exceeds the threshold, secondary analysis processing is applied to the image data or the primary analysis result. The secondary analysis processing is performed for analyzing the factor of the fact that the result of the primary analysis processing exceeds the threshold. A user is notified of the result of the secondary analysis processing together with the corresponding image data, for example. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method and device for optical recording/reproducing, capable of suppressing the effect of a gap change amount on recording/reproducing characteristics during fast rotation, and an optical pickup device. SOLUTION: The method for performing recording and/or reproducing by applying a near field light to an optical recording medium 1 includes a step of applying two or more light beams as near field light beams to the optical recording medium 1, a step of detecting the information on a distance from the optical recording medium 1 based on one of the two or more light beams applied to the front side of a scanning direction with respect to the optical recording medium 1, and a step of performing recording compensation and/or reproducing compensation by near field light application, by the remaining light beams based on the distance information.

Abstract:
PROBLEM TO BE SOLVED: To provide a tilt detecting method and a tilt regulating unit which can detect the inclination of a near-field light radiating means and an object to irradiate by using a comparatively simple optical system, an optical pickup device capable of adjusting the inclination of the near-field light radiating means in a simple configuration, and an optical recording reproducing device thereof. SOLUTION: The relative inclination of the near-field light radiating means 1 and the object to irradiate (optical recording medium 10) is detected by radiating at least one beam to a position shifted off from the optical axis of the near-field light radiating means 1 and detecting the amount of all the return light of this beam reflected on the irradiated object (optical recording medium 10).

Abstract:
PROBLEM TO BE SOLVED: To provide an optical recording medium suitable for a near field recording and reproducing system. SOLUTION: In the optical recording medium, first and second groove structures GV1 and GV2 having e.g. widths and depths different from each other are formed as physical structures and two land parts LD1 and LD2 between the first and the second groove structures are specified to be recording and reproducing tracks, that is, the two recording and reproducing tracks TK1 and TK2 run side by side. By irradiating the recording and reproducing tracks running side by side with one laser spot respectively, that is, two laser spots SP1 and SP2 to perform recording and reproduction, enhancement of a transfer rate can be realized without rotating the optical recording medium at higher speed. Characteristics of cross-write, cross-erase and cross-talk are enhanced by specifying the two lands sandwiching the second groove structure GV2 to be the recording and reproducing tracks.
