  • Patent number: 7263043
    Abstract: An optical disk drive for optimizing laser power to be used at the time of recording operation. In a DVD-R drive and a DVD-RW drive, a controller performs OPC to set recording power and records RMD serving as recording management data in an RMA serving as a recording management area. The RMD are verified. When the RMD can be read, the number of PI errors in the RMD is detected. If the number of PI errors is equal to or less than an allowable value, data are recorded in a data area at that recording power. If the number of PI errors exceeds the allowable value, OPC is again performed, to thereby reset the recording power.

  • Patent number: 7083101
    Abstract: A signal obtained by optically scanning a bar code is subjected to differentiation to obtain differential data. Peak-to-peak distances are calculated from the differential data. When a peak-to-peak ?Tx distance is y times of a basic width, frequency f(x,y) will be, f(x,y)=y/?Tx. A frequency map is prepared from the frequencies calculated. Transition routes in which one frequency each is selected. from each of the peak-to-peak distances, are formed. A transition route for which an error in frequencies is the least is taken as the most suitable transition route. An average of the frequencies included in the transition route is taken as a frequency f0 of the basic width.

  • Patent number: 7077322
    Abstract: An extractor extracts a part that is apparently a bar-code signal from a signal that is subjected to opto-electric conversion. A narrow-band differential processor forms a waveform of an edge by differentiating by using a module frequency. The module point extractor extracts the module point from the waveform. The maximum likelihood judgment processor 5f performs ternarizing based on a maximum likelihood method by using broader information.

  • Patent number: 7055748
    Abstract: A signal fetching unit fetches a signal that includes binarized information disposed with a predetermined information length, from a barcode. A module-frequency extracting unit extracts a module frequency equivalent to a basic unit length in the binarized information from the signal. A frequency shifting unit shifts a frequency to 0 Hz based on the module frequency for the signal. A low pass filter passes a low frequency component included in an output signal from the frequency shifting unit. A module-point extracting unit extracts a module point synchronized with the signal and that has the module frequency, based on the module frequency extracted and an output signal of the low pass filter. A demodulating unit demodulates a character of the barcode based on the module point extracted.
