摘要： Method and apparatus for optically detecting information from a recording medium in which pits are formed by thermal energy of a light spot to record the information. A reproduction spot is irradiated onto the recording medium to produce a detection signal. From a differential signal of the detection signal, a signal indicative of zero points of the differential signal and a signal indicative of the presence of the pits are detected, and both the signals are used to detect positions of the pits. For stable and accurate detection of the pit position, the relation between pit size W and reproduction spot size W.sub.s is prescribed and the pit size and reproduction spot size are so set as to satisfy 0.45.ltoreq.W/W.sub.s .ltoreq.0.75.

摘要： In a light spot control signal generating device, a light spot is irradiated on a recording medium having tracks on which information is recorded. In order to jump the light spot from a track being scanned thereby to an adjacent track, a signal representative of light quantity of reflection or transmission of the light spot and a track error signal are detected. The two signals are used to judge whether the light spot has passed through an edge of the track. The track error signal is also used to detect a signal representative of an instant at which the light spot is present at the middle point between adjacent tracks, and this signal is used as a timing signal for changing the polarity of a control signal applied to a spot light deflector.

摘要： [Object] To provide a pointing system capable of presenting an intuitive operational feeling to a user.[Solving Means] A pointing device includes a casing, a tactile sense presentation section, and a sensor section. The sensor section detects an operation for the casing and outputs an operation signal for controlling a movement of a pointer on a screen. The control apparatus includes an area setting section and a signal generation section. The area setting section sets a first area that belongs to an inside of a display area of an object on the screen, a second area that belongs to an outside of the display area of the object, and a third area that belongs to a boundary portion between the first area and the second area. The signal generation section calculates a position of the pointer based on the operation signal to generate, when the pointer is located in the first area, a control signal by which the tactile sense presentation section is driven in a first drive mode and generates, when the pointer is located in the third area, a control signal by which the tactile sense presentation section is driven in a second drive mode.

摘要： There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having a low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.

摘要： An information memory device using an electromagnetic-wave resonance phenomenon is provided to achieve both high density and long-period storage of stored data. Memory cells are three-dimensionally arranged in the inside of a solid-like medium which is not contacted with a surface of the medium, and the memory cell has resonance characteristics to electromagnetic waves depending on the space coordinates of the memory cell. For the medium, a material is selected so that an electromagnetic wave having the resonance frequency of the memory cell. By observing absorption spectra of the irradiated electromagnetic wave or emission spectra after the absorption, three-dimensional space coordinates of the memory cell are calculated.

摘要： Provided is a recording and retrieval apparatus for a multi-layer optical disk. A multi-layer optical disk in which a plurality of recording layers and a single servo layer are combined to form a set is used. A spot for the servo layer and a spot for the recording layers are turned on in a time-sharing manner. Servo signal detection areas are formed discretely in the servo layer. The servo signal detection areas and data recording areas are provided so as not to overlap each other when viewed from the spot incident side. Thus, separation of data from each of the layers can be done by even a single photodetector without interference.
