Title: Amplifying device
Inventor: CHOKAI YOICHI
IPC: H03F1/26
Filed: 1989-05-10
Abstract: PURPOSE:To prevent the free-running oscillation by biasing an amplifying part and an interface part via a power supply part which works independently. CONSTITUTION:At an amplifying part 100, the input signal received by an input terminal IN is amplified with the prescribed gain via a transistor TR Q1 and sent to an interface part 200 after undergoing the conversion of impedance via a TR Q2 of an emitter follower. The part 200 includes a 2-stage emitter follower type TR amplifier which receives the bias voltage from a power supply part 301 which works independently of a power supply part 300. The part 200 is connected to a load and receives the bias voltage from the part 301 independent of the part 100 to work. Thus only the part 200 is affected by the AC fluctuation of voltage caused between output terminals OUT1 and OUT2. Thus the part 100 is not affected. As a result, the free-running oscillation is prevented.

Abstract: PURPOSE:To simultaneously satisfy two conditions, that is, a simple constitution of an electric circuit and no degradation of the reproduction C/N with regard to a magneto-optical head device which uses a diffraction element for detection of the error and information signals. CONSTITUTION:The reflected light of a disk 5 is separated into three beams, i.e., a 0-order beam (normal light component) and the + or -1st-order diffracted beams (abnormal light component) by a polarizing simple diffraction grating 34 which chiefly diffracts only a specific polarizing component out of the incident light. The 0-order beam of the grating 34 is separated into three beams, i.e., a 0-order beam and the + or -1st-order diffracted beams by a polarizing hologram 35 which chiefly diffracts only the polarizing component orthogonal to the polarizing component of the grating 34 out of the incident light. Then the error signal is detected with use of a partial beam that is separated by the hologram 35 from the 0-order beam of the grating 34. Meanwhile the information signal is detected based on the difference between another beam separated from the 0-order beam of the grating 34 by the hologram 35 and the + or -1st-order diffracted beams of the grating 34.
