Title: Driving method for driving bistable semiconductor laser
Inventor: MUTSUKAWA HIROYUKI
IPC: H01S5/06
Filed: 1988-02-24
Abstract: PURPOSE:To set a bistable laser diode from the off-state to the on-state reliably only by small optical power, by selecting the wavelength of the light to set the bistable laser diode from the off-state to the on-state. CONSTITUTION:When driving a bistable laser diode 5, the incident light power and injection current are set to that the bistable laser diode operates in a bistable region 6 where the bistable laser diode can be on or off selectively. The bistable laser diode is set from the off-state 4 to the on-state 3 by being applied with the incident light whose wavelength is almost the same as the wavelength (lambdaa, lambdab, lambdac, lambdad) to give the peak to a spontaneously emitted light spectrum 7 of the bistable laser diode 5 when it is in the off-state 4. To set the bistable laser diode from the off-state to the on-state, light sent out from a semiconductor laser 8 is used. By this, the semiconductor laser 8 and the bistable laser diode 5 are kept at a constant temperature. By controlling the temperature of each of the laser diode and the bistable laser diode, the optical power to be required for setting the bistable laser diode from the off-state to the on-state can be minimum and the oscillation wavelength of the semiconductor laser 8 and the bistable laser diode 5 can be set.

Title: Recording device for video signal and pcm audio signal
Inventor: MURAKAMI DAISUKE
IPC: G11B5/02
Filed: 1986-02-26
Abstract: PURPOSE:To eliminate disturbance for the detection of a discrimination pilot signal in a reproduction time, and to perform an accurate discrimination, by overlapping and recording the discrimination pilot signal on an audio signal for every other track in a track width direction. CONSTITUTION:When a head switching pulse S1 is positioned at an L, and a change-over switch 4 is positioned at a channel B side in a PCM sound recording time, a control signal S4 is sent to a discrimination pilot signal generator 12 from a controller 11, and the discrimination pilot signal is overlapped and recorded on a track B, not on a track A. In the reproduction time, the discrimination pilot signal is detected by deriving the output of a regenerative amplifier 8b of channel B. In such a case, since no discrimination pilot signal is recorded on the track of channel A even when a stroke is present from the track of channel A, no disturbance for the detection of the pilot signal occurs, and therefore, the accurate discrimination can be performed.
