PROBLEM TO BE SOLVED: To improve a transfer rate by rotating an optical disk medium at a high speed while maintaining a narrow gap between the optical disk medium and an objective lens in a near-field system. SOLUTION: In a low speed rotation region during start, by transmitting power by a sub motor 123 from a sub motor pulley 122 to a main motor pulley 121, a spindle motor (main motor) is rotated. Then, by moving a sub motor attaching plate 129 on which the sub motor pulley 122 is mounted by a release motor 133 after a gap servo is stabilized in the rotating state and switching to high speed rotation by the main motor alone, the high speed rotation is achieved in the state of maintaining the narrow gap.

PROBLEM TO BE SOLVED: To remove an foreign material stuck to an objective lens in a disk unit with simple mechanism. SOLUTION: A tracking error detecting part 331 detects a tracking error signal based on a reproduced signal read out from an optical disk. When the tracking error signal is in a state in which it exceeds the supremum or the lowest limit of the prescribed amplitude range, it is estimated that a foreign material is stuck to an objective lens as a main cause, a tilt control part 342 performs tilt operation for a tilt adjusting part 343 to remove the foreign material. Confliction between the objective lens and the optical disk by tilt operation is not caused even in a near field system by operating gap servo by a gap servo control part 322.

PROBLEM TO BE SOLVED: To perform adjustment so as to decrease eccentricity quantity of by detecting eccentricity quantity when a disk type recording medium is loaded. SOLUTION: A disk loading part 350 loads a disk type recording medium 390 by loading force of at least two stages. A disk image pickup part 310 performs image pickup of the prescribed region of the disk type recording medium 390. A boundary detecting part 320 detects respectively boundary positions included in respective regions in which image pickup is performed a plurality of times. An eccentricity quantity calculating part 330 calculates eccentricity quantity from distribution of the boundary positions. A loading position adjusting part 360 adjusts a loading position based on the calculated eccentricity quantity. The disk loading part 350 loads the disk type recording medium 390 by more strong loading force after finish of adjustment of the loading position. Also, when the calculated eccentricity quantity exceeds a limit value, the disk loading part 350 releases loading and unloads the disk type recording medium 390. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To eliminate dust or the like any time so that dust or the like are not stuck to an attachment part between an attachable and detachable recording medium and it, in a recording medium driving device. SOLUTION: A blower 140 performs ventilation for a clamp 110 when loading operation for clamping an optical disk is performed for the clamp 110, and performs ventilation for an actuator 120 other than the case. Also, the blower 140 performs ventilation for the actuator 120 when the optical disk is clamped to the clamp 110, and performs ventilation for the clamp 110 when the optical disk is not clamped to the clamp 110.

PROBLEM TO BE SOLVED: To provide an optical disk driving unit capable of properly controlling a gap by removing dusts on a disk, an optical disk device having the same mounted thereon, and its driving method. SOLUTION: Since the optical disk driving device 1 includes a contact type lens cleaning mechanism 60 and a disk cleaning mechanism 80, dusts are removed more easily as compared with the conventional art. Thus, gap servo control and initial tilt adjustment are properly carried out. In addition, needless to say, tracking servo control, tilt servo control, and the like are properly carried out.

PROBLEM TO BE SOLVED: To provide an electrochemical display device with an excellent cycle characteristic of a black reflectance by preventing image persistence and an electrochemical display method. SOLUTION: In the electrochemical display device and in the electrochemical display method, a plurality of transparent electrodes and a plurality of counter electrodes disposed so as to make their mutual intersections constitute pixels and an electrolyte layer interposed between the transparent electrodes and the counter electrodes and containing a metal ion are arranged. To pixels to which a picture is to be written, the picture is written by applying a first writing voltage higher than an absolute value of a threshold writing voltage between the transparent electrodes and the counter electrodes and subsequently applying a second writing voltage lower than the absolute value of the threshold writing voltage between them so as to deposit a metal on the transparent electrode side. From pixels from which the picture is to be erased, the picture is erased by applying a first erasing voltage lower than an absolute value of a threshold erasing voltage between the transparent electrodes and the counter electrodes and subsequently applying a second erasing voltage higher than the absolute value of the threshold erasing voltage between them so as to dissolve the deposited metal on the transparent electrode side.

PROBLEM TO BE SOLVED: To provide a virtual image with a shape suitable to a video. SOLUTION: In the case a video is broadcasted as a movie and a drama having an aspect ratio of 16:9 by a high definition television broadcast, in the display device 4, a large virtual image is formed in a position far away from a user by about 15m. Alternatively, in case that a video is broadcasted as a television signal having an aspect ratio of 4:3 by an NTSC system, in the display device 4, a middle-sized virtual image is formed in a position comparatively close to the user by about 3m. Whether the video is broadcasted by the high-definition television broadcast or the NTSC system is decided based on the synchronizing signal of the television signal. COPYRIGHT: (C)2005,JPO&NCIPI
