IPC: G11B7/125
Filed: 1992-08-31
Abstract: PURPOSE:To provide a high precision plotting regardless of the kinds of laser beams and impressed signals by providing an electro-optical modulator which intensitymodulates a laser beam based on an impressed signal electrical field and an acoustooptical modulatior which intensity-modulates the output of the electrooptical modulator. CONSTITUTION:A laser beam L emitted from a laser light source 1 is intensitymodulated by an electro-optical modulator(EOM) 2 based on a direct current voltage V supplied to the EOM 2. At that time, the EOM 2 is feedback- controlled so as to make the optical output of the laser beam L constant by a feedback system 14 and thus, the output of the laser beam L, which passes the EOM 2, is stabilized. The laser beam L passed the EOM 2 is intensity- modulated by an acoustooptical modulator(AOM) 3 based on ultrasonic waves W supplied to the AOM 3. Thus, this optical recording device plots recording patterns on a photoresist film 8 with a high precision regardless of the kinds of the laser light source 1 and the kinds of impressed signals.
