摘要： Disclosed is an optical disc apparatus that sets a plurality of virtual zones, which correspond to a plurality of zones that are arranged in the radial direction of an optical disc, for a plurality of recording layers of the optical disc. When a servo signal distortion is detected in a virtual zone to change the rotation speed of the optical disc to a low speed in the virtual zone during an information recording or reproduction operation relative to a first recording layer, the optical disc apparatus stores the change information. When a recording or reproducing operation is to be performed in a virtual zone of a second recording layer, which is in the same disc radial position as the virtual zone of the first layer, the optical disc apparatus changes the rotation speed of the optical disc for the virtual zone to a low speed in accordance with the change information.

摘要： In an optical disc device employing a CLV method, executing pickup return processing when focus drop occurs during recording poses problems of increased waiting time for rotation and increased focus servo recovery processing time. When defocusing occurs and focus pull-in cannot be achieved by retry, a first rotation frequency at a radial position thereof is calculated. Next, a second rotation frequency at the innermost circumferential position at the current speed is calculated. Next, a third rotation frequency at a radial position where recording is restarted after focus servo recovery is calculated. Next, a fourth rotation frequency at pickup return position at a different speed is calculated. Next, based on the relationship among the first to fourth rotation frequencies described above, a rotation speed at pickup return is selected so that a rotation frequency difference becomes the smallest in all conditions: at pickup return from defocusing, servo recovery after pickup return, and access operation after the servo recovery.

摘要： An optical disc apparatus is designed to perform focus control of an objective lens of an optical pickup by generating a first focus error signal of an astigmatism method from a signal based on 0-order light of a reflected laser beam, as well as generating a second focus error signal of a differential astigmatism method from the signal based on the 0-order light and from a signal based on ±1-order light. The focus control of the objective lens is performed by the second focus error signal during recording or reproducing operation within a recording layer of an optical disc. The focus control is performed by the first focus error signal when a focus jump is performed in response to switching of the recording layer of the optical disc.

摘要： A display device of the present invention prevents the deterioration of display quality even when input video data are changed. In a matrix type display device, lines of video data are inputted to the data driver circuit one after another for every horizontal scanning period of the video data. The data driver circuit alternately repeats (i) a first step for generating a display signal corresponding to each one of the lines of the video data one after another for every fixed period and outputting the display signal to the pixel array N-times (N being a natural number equal to or greater than 2) and (ii) a second step for generating a display signal which makes the luminance of the pixels lower than the luminance of the pixel in the first step for the fixed period and outputting the display signal to the pixel array M-times (M being a natural number smaller than N). The scanning driver circuit alternately repeats (i) a first selection step for selecting the plurality of pixel rows for every Y rows (Y being a natural number smaller than the N/M) sequentially from one end to another end of the pixel array along the second direction in the first step and (ii) a second selection step for selecting the plurality of pixel rows other than the pixel rows (Y×N) selected in the first selection step for every Z rows (Z being a natural number not smaller than N/M) sequentially from one end to another end of the pixel array along the second direction in the second step. Further, the outputting of N pieces of display signals in the first step and the outputting of M pieces of display signals in the second step are performed in response to periods which are obtained by evenly dividing the N-pieces of the horizontal scanning periods which are sequentially outputted into (N+M) pieces of periods.
