摘要： An optical information recording device for recording information utilizing holography comprises a recording medium moving means for moving a recording medium, a follow-up control circuit (94) for controlling an irradiation position, and a signal converting means (51) for obtaining a reproduction signal from an address servo-control area including a light source for radiating an information beam and a reference beam onto the recording medium. The follow-up control circuit is composed of a binary-coding means (52) for binary-coding the reproduction signal and a follow-up signal circuit (50), and detects the travel amount of the irradiation position moving means and generates, according to the travel amount detected and for a specific time during which the irradiation position of the information beam and the reference beam follows, an irradiation position control signal for controlling an irradiation position moving in one information recording area through an output terminal of a gain control amplifier (47).
