    摘要： A laser drive integrated circuit and an optical disk apparatus using the laser drive integrated circuit for forming high-density marks. The optical disk apparatus includes a drive waveform information storage unit for storing at least one information of a drive waveform for driving a laser diode in response to a binary recording signal to be recorded in a recording medium, and a drive waveform decoder for decoding the drive waveform based on the information stored in the drive waveform information storage unit. A recording strategy can be changed in accordance with variations and fluctuations of recording media or characteristics of the recording media, while at the same time reducing a number of signal lines in flexible wiring and alleviating effects of signal distortion in the signal lines.

    摘要： The present invention is a method for manufacturing a semiconductor apparatus including a chip which is fabricated in large numbers on a wafer and has a plurality of information blocks. In the method, a unique information bit is written in a chip discrimination block of each chip within a shot, which is a segmented region of the wafer, by a fixed pattern method. In addition, an information bit uniquely given to each shot within the wafer is written by a mask shift method. Further, an information bit uniquely given to each wafer is written in a wafer discrimination block of the chip which is fabricated on the wafer by the mask shift method and mask combination method.

    摘要： A recording medium in which information is to be recorded is permitted to get into a first state by a first power level of an energy beam and permitted to get into a second state by a second power level higher than the first power level of the energy beam. The information is recorded on the recording medium by moving the energy beam and the recording medium relatively to each other and irradiating the recording medium with the energy beam so that the first and second states are formed with predetermined lengths and at predetermined intervals on the recording medium. Four power levels (first, second, third and fourth power levels) are used as the power level of the energy beam. The information is recorded while the second power level is increased to x times and the first, third and fourth power levels are increased to y times. The information recorded as described above is reproduced, and reproductive jitter is observed. The magnification factors x and y are adjusted so that the value of the reproductive jitter is not larger than a predetermined value.
