Title: Optical recording and reproducing device
Inventor: NAGAAI KAZUMICHI
IPC: G11B7/12
Filed: 1984-03-07
Abstract: PURPOSE:To attain accurate reproduction by using laser light shorter in the wavelength than the laser light for recording for the purpose of reproduction. CONSTITUTION:An optical disc 1 consists of a transparent substrate 2, a recording layer formed with a thin film 3 with Ge having small attenuation coefficient and with a thin film 4 made of Al having a large attenuation coefficient and an Al plate 6 as a reflecting plate. The thin films 3, 4 at a position on which a laser beam is irradiated via an optical head 8 are diffused mutually to form a transparent thin film (recording pit) 7. A reproducing beam having a short wavelength (0.78mum) and a recording beam having a long wavelength (0.83mum) respectively from semiconductor laser oscillators 9, 10 form an optical spot to the recording layer 5 via collimator lenses 11, 12, a polarized beam splitter 13, a half mirror 14, a totally reflecting mirror 15 and an objective lens 16 to attain recording and reproduction. Since the diameter of the reproducing spot is smaller than the recording spot, accurate reproduction is attained.

Abstract: PURPOSE:To prevent a clock from mixing into a receiving echo as a noise, by controlling so that oscillation of a clock is stopped during the period for receiving an ultrasonic echo. CONSTITUTION:When the electric power source Vcc is turned on, the input terminal of a monostable multivibrator 1 or 2 is applied once, the monostable multivibrator 1 outputs a pulse of pulse width T1, and the monostable multivibrator 2 outputs a pulse of pulse width T2. The monostable multivibrator 1 and 2 constitute a pulse oscillator, and are turned on and off in the section T1 and T2. The counter 4 leads in the Q' output of the monostable multivibrator 2, counts the pulse of the n-1-th, and after that, outputs a clear pulse. By this clear pulse, the counter 4, and the monostable multivibrator 1 and 2 are cleared. Also, this clear pulse triggers the monostable multivibrator 3, and the monostable multivibrator 3 generates a pulse of pulse width T3. The monostable multivibrator 1 receives this pulse, and starts oscillation again. Accordingly, a control signal which oscillates in the period of n(T1+T2), and stops its oscillation in the T3 period is output from the terminals 5, 6, and transmission of an ultrasonic beam is controlled.
