摘要： PURPOSE:To obtain the optimum form of a recording bit and to improve the S/N of a reproduction signal by controlling the light emitting output of a light source in response to the difference of light quantity between both secondary beams that are reflected by a recording medium or transmitted through the recording medium. CONSTITUTION:The laser light of a semiconductor laser 7 is divided by a grating 5 into a 0-order main beam and + or -1-order secondary beams. An information bit 25 is formed by the 0-order light 24, and the formation of the bit 25 is detected by a secondary beam 26. While a secondary beam 27 is irradiated to an unrecorded part. The outputs of sensors 14 and 15 of beams 27 and 26 undergo the voltage conversions 16 and 17 and then the difference of both outputs is obtained. Then only the detection signal of the bit 25 is obtained and supplied to an LPF19. When a recording bit has a smaller form than the optimum bit, the output VC of the LPF19 is reduced. A current source 20 compares the voltage VC with the set voltage V0 of an input part 21 and increases the output current according to an amount of reduction. Thus the light emitting output of the laser 7 is increased.

摘要： PURPOSE:To write or read surely information on a recording medium with no effect due to the change of the atmospheric temperature of the recording medium, by changing the laser power of a semiconductor laser in response to the change of the atmospheric temperature of the recording medium. CONSTITUTION:A thermistor 20, i.e., a temperature sensor is attached at a place near a recording medium to detect the atmospheric temperature of the recording medium. The output voltage of a temperature detecting circuit, i.e., an operational amplifier 24 is reduced as the atmospheric temperature of the recording medium increases. The digital signal, i.e., the information data to be written to the recording medium turns on and off a transistor TR34, and therefore the light of a semiconductor laser 37 is blinked. A TR32 is turned off (on) when the TR34 is on. Therefore the current flowing to the laser 37 is equal to the output current of a constant current source consisting of an operational amplifier 27 and a TR28.

摘要： PURPOSE:To attain stable tracking and focusing control despite the fluctuation of the reflected light quantity caused on the surface of a recording medium, by controlling the temperature of a light source according to the quantity of the light reflected by the medium or transmitted through the medium. CONSTITUTION:When the reflection factor increases after replacement of a recording medium 1, the difference between the output voltage of an adder circuit 18 and the set voltage VR increases. A Peltier element 14 is driven by said difference of voltage to heat up a semiconductor laser 3. The laser power is reduced when the temperature of the laser 3 is increased by heating. The laser power is reduced down until the output voltage of the circuit 18 is equal to the voltage VR. Then the laser power is kept at a constant level. Thus the recording and reproducing actions are carried out as prescribed. In such a way, the laser power is kept at a fixed level despite the change of the quantity of the reflected light sent from the medium 1. In such a way, the variance of both auto-focusing and auto-tracking signals is prevented.

In addition, a dither matrix ROM18 switches the dither patterns within a sheet of original according to the character region and the photoregion.
