    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.

    摘要: A digital broadcasting receiver judges whether or not a received program is a data broadcasting program. When the received program is the data broadcasting program, processing for judging a remote control signal from a remote control transmitter is performed as usual. When it is judged that the remote control signal is a remote control signal related to a key associated with channel selection, however, processing corresponding to the signal is not performed. That is, processing for judging whether or not the received program is the data broadcasting program to automatically nullify (lock) a channel change.
