    摘要: A process for forming a glass sheet, which is a process for continuously forming a glass sheet, and which comprises a step of introducing a vapor film-forming agent, which is not vapor at least around room temperature and which is vapor at a temperature above the glass transition point of the glass, into a support composed of a structure or a material capable of internally containing liquid, and a step of sliding the support and the glass of which temperature is above the glass transition point against each other via a thin layer of a vaporized vapor film-forming agent.

    摘要: An optical recording apparatus includes an optical system to focus a beam of light onto an optical recording medium; a laser source to generate the beam; a laser driver that modulates the output of the beam according to digital information to be recorded; and a controller that performs control in such a way that the average power per unit recording time of the beams used to record digital information "1" (or "0") and digital information "0" (or "1") onto the recording medium are virtually equal, and so that the peak power of the beams used to record the digital information "1" (or "0") and the digital information "0" (or "1") differ from each other.

    摘要: A focus error detecting method and an optical head using it. In the focus error detecting method, a light beam is emitted from a light source, the beam is given positive and negative astigmatism by a diffraction grating or an acoustooptic element in a focusing optical system, beams thus formed are focused on an information recording surface, the beams reflected from the information recording surface are received by photo-detecting elements in separated optics, the reflected beams with positive and negative astigmatism are compared with each other to take a difference in a focus error detecting circuit, and a focus error detecting signal is obtained on the basis of the difference. The focus for the optical head can be adjusted using the focus error detecting signal.

    摘要: A signal processing method for recording and playing back recorded data with decreased detection errors originating from residual marks characteristic of an overwrite medium is performed by 8/9 modulating input data, and by inverting the polarity of the modulated data string at each "1" bit to produce a DC-free recording pulse. The thus-recorded signal is played back through a playback equalizer 8 before being converted by an A/D converter 9 into digitized amplitude data. The digitized data are processed to determine an identification level, which identification level is stored as well as used to determine displacement quantities for quantized bits derived from the analog playback signal. The number of "1" bits is counted by a counter 20, and an error in the number of "1" bits is detected by a comparator 21. An error bit decision circuit 22 determines which bit is most likely to be erroneous on the basis of displacement quantity, and the likely erroneous bit is corrected prior to outputting the data for 8/9 demodulation.
