Title: Optical information processor
Inventor: KATOU SHIGEO
IPC: G11B7/09
Filed: 1984-04-25
Abstract: PURPOSE:To always ensure focusing to a recording medium by unifying an objective lens which focuses the light given from a light source on a revolving medium, a photodetector which detects the reflection from the medium and an optical element which separates the irradiated light from the reflected light, giving microvibrations of a fixed frequency to these unified elements and receiving the reflected light given from the recording medium by a photodetector to detect the out-of-focus degree and its direction from the intensity of the output of the photodetector. CONSTITUTION:The distance between an objective lens 42 and the surface of a video disk 36 is set at xo, and E is set at maximum value Eo when x=xo is satisfied. Then an objective lens is vibrated toward its optical axis at a point xA larger than xo, a vibrating waveform having a 180 deg. phase shift appears as compared with the vibrating phase of the objective lens with the output voltage of the photodetector. In case the xA is smaller than the xo, a vibrating waveform of a phase coincident with the vibrating phase appears. In an actual operation, the control signal is transmitted from a control circuit 47 based on the output of an LPF46. This control signal is amplified by a current amplifier 48 and then applied to a voice coil 14. Thus the control is possible so as to set (xA-xo) at zero, i.e., so that the focal point is always coincident with the surface of a video disk at all times.
