摘要： A magneto-optical head for reading information from a recording medium, the head having a laser-based optical system that comprises two light paths, a first path from the source to and continuing through or reflecting from medium and a second path in a different direction which directs light from the medium to a detector. The second path includes a dual prism multiplying element (Wollaston prism) for dividing the reflected beam into three distinctly oriented beams, and a multi division photodetector for detecting a servo signal by the astigmatism method and an information signal by a differential polarization method.

摘要： An optical information recording and reading apparatus checks the recording of information simultaneously with recording of said information by means of a recording laser beam by detecting a deflected portion of the reflected beam of the recording laser beam from an optical recording medium. An intensity differential signal is generated by monitoring different portions of the deflected portion of the reflected beam. The intensity differential signal is insensitive to intensity changes in the recording laser beam. The accuracy of the recorded information is determined by sensing the change of polarity of the intensity signal. An error signal is generated as a function of the polarity of the intensity differential signal to re-record information not recorded properly.

摘要： A position control system has a motor for moving a movable member which is driven, at first, by a non-controlled signal. Responsive to a position error signal which represents a difference between a present position and a commanded position, and to a velocity signal which represents a velocity of the movable member, a deceleration signal is generated for positioning the movable member at the commanded position. When it exceeds a predetermined level, the deceleration signal is applied to the motor, instead of the non-controlled signal.
