摘要： The present invention aims to, when recording pulse information are transmitted to a laser driver lying over a pickup through an optical disk, reduce the number of transmission paths or lines from a conventional transmission method and avoid degradation of recording performance due to transmission path characteristics upon fastening of a recording speed thereby to provide stable recording performance at high-speed recording. The invention of the present application reduces the number of transmission signals by encoding multi-level laser pulse information transmitted by the laser driver. Further, gray codes are used for encoding to reduce constraints of skew between bits. Furthermore, encoding is executed using each state transition and the state transitions are switched according to each recording mark and space, thereby reducing the occurrence of a short pulse on each transmission path. In addition, the presence or absence of the encoding is switched to enable signal transmission, thereby making it possible to make compatible adaptation to complex laser pulse information and adaptation to high-speed recording.

摘要： A laser driver drives a laser diode by producing a write strategy, that is, a recording waveform from a recording clock and a modulated signal. In one embodiment, a laser driver produces the waveform of a driving signal, which is used to drive a laser diode, using a record data signal that represents record data to be recorded on a recording medium. The laser driver comprises an internal clock production circuit that produces an internal clock synchronous with the record data signal, and a strobe circuit that strobes the record data signal according to the internal clock.

摘要： Solid-state imaging elements each having a smaller number of pixels are employed to realize an imaging device for taking a high-definition picture which is four or more times larger in the number of pixels than each of the solid-state imaging elements, and also an apparatus for recording/playing back (or transmitting) the high-definition picture. A two-dimensional space which includes, at least, nH spatial sampling points in a horizontal direction and nV spatial sampling points (nV lines) in a vertical direction, totaling (nH.times.nV) spatial sampling points, is imaged under the condition that light is sensed at, at most, 1/2 of the sampling points of the two-dimensional space. Thus, the imaging device delivers as its output a video signal containing effective pixel information items which correspond to the light-sensed sampling points and which are, at most, (nH.times.nV)/2 in terms of the number of pixels.
