Abstract
PURPOSE: To make it easy and accurate to duplicate disks by generating read beam light and recording beam light at a time by one laser light source and by recording on a duplicated disk read information obtained from a master disk.
CONSTITUTION: Laser beam light l0 output from laser oscillator 24 as a light source is led to half mirror 26 by way of fixed reflecting plane mirror 25a. Then, half mirror 26 separates laser beam light l0 into beams l1 and l2 and beam l1 is led to optical read system 27. Beam light l2,on the other hand, is reflected by fixed reflecting mirror 25b and supplied to light modulator 40, where it is separated into recording beam l7 and focusing beam l8. In accordance with a recording information signal, modulator driver 38 drives light modulator 40 to perform on-off modulation as to only recording beam l7. Thus, the metal coating of optical disk 12 deforms in accordance with the modulation of l7 and on duplicated disk 12, the same pit line as that formed on optical disk 11 is formed.
