    摘要： A data signal to be transmitted is supplied to a modulator of a transmitter, and the modulator modulates the output of a blue light-excited white LED and outputs blue LED light and phosphor light. The modulated blue light enters to a photo-electric converter through an LED light transmission color filter. The modulated phosphor light on the other hand enters to another photo-electric converter through a phosphor light transmission color filter. The photo-electric converters convert incident light to electric signals. The converted signals are amplified by amplifiers. Then, equalizers emphasize the harmonic component therein according to the response characteristic of the blue light and the response characteristic of the phosphor light for reduction of the dullness of waveforms.

    摘要： It is an object of the present invention to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly to provide a method especially effective when applied to code identification methods, such as PRML, wherein codes are identified based on amplitude information of an RF signal. In order to accomplish the object, an RF signal received from a photo-receiving part 108 of a pickup is converted into sampling data by an A/D converter 300, and a Viterbi decoder 302 performs code determination using the sampling data. Codes included in a reproduction signal are then determined by synchronizing recording pulses with the reproduction signal using the result of the code determination. Then, the result is used to specify a part to be detected in the codes, and finally an amplitude of the specified part is detected.

    摘要： In one inventive aspect, a transmitter is provided. In the transmitter, a modulator supplies an electrical current based on a digital transmission electrical signal to a white LED, which emits light including a plurality of wavelengths into the air. A light detector separates a light signal component having a blue wavelength from the emitted light using an optical filter and converts the signal component to a monitoring electrical signal. A waveform control circuit outputs a control signal so that the time delay of the waveform of the monitoring signal with respect to the waveform of the transmission electrical signal is less than or equal to a predetermined value. The modulator corrects the amount of the electrical current supplied to the white LED on the basis of the control signal. In another inventive aspect, a receiver is provided. In the receiver, an optical filter separates a light signal component having a blue wavelength and a light detector detects substantially only the light signal component having a blue wavelength.
