Abstract
PURPOSE:To deflect pulse light in a specific direction and to record information in a recording material which needs high energy by driving plural laser beams by a driving means based on the recording information so that the pulse light is oscillated from the respective laser beams. CONSTITUTION:Respective collimator lenses C1-C3 are arranged on the laser oscillating sides of three semiconductor lasers LD1-LD3 in a laser recording device. The laser light is condensed by a condenser 10 arranged on the light beam outgoing side of the lenses C1-C3 and made incident on an acoustic optical deflecting unit 12 which is arranged near the focus of the lens 10. The deflecting unit 12 is driven with ultrasonic frequency in which diffracted light outputted from an AOD driver 16 is nearly in proportion to acoustic frequency f1-f3 and the laser outgoing light from the deflecting unit 12 is made high energy. And the driver 16 is actuated synchronously with the oscillation of the lasers LD1-LD3 with the pulses outputted from a synchronizing signal oscillator 14 is which a dot signal is inputted.
