Abstract

PURPOSE: To sufficiently compensate inter-beam cross modulation with high accuracy by disposing compensating beams on both sides of recording beams.
CONSTITUTION: An oscillator OSC10 corresponding to a compensating beam ID1 and oscillators OSC11WOSC13 corresponding to recording beams I1WI3 are connected a synthesizer Σ1 by way of mixers M10WM13, and an oscillator OSC24 corresponding to a compensating beam ID2 and oscillators OSC21W23 corresponding to recording beams I14WI16 are connected to a synthesizer Σ2 by way of mixers M21W M24. With this arrangement, the carriers from the oscillators OSC10, OSC24 are modulated in the mixers M10, M24 by the dummy signals comprising adding a reference signal to the image signals followed by inversion and amplification, and the carriers from the oscillators OSC11W23, OSC21W23 in the mixers M11W13, M21W23 by the picture signals. After these are synthesized respectively in the synthesizers Σ1, Σ2, they are further synchesized in the synthesizer Σ3, thence it is applied to an acousto-optic element AO, whereby the undulation and asymmetry of the bands of the acoust- optic element AO are compensated.
