<P>PROBLEM TO BE SOLVED: To provide an optical information recorder capable of stably operating one controlled object even when one controlled object is controlled by three kinds of systems. <P>SOLUTION: The optical information recorder is constituted by providing a linear speed dependent recording power setting device 22 which changes recording power according to linear speed during recording, a recording power correcting device 21 which measures reflected light from the recording medium to correct the recording power and an LD drive current controller 23 which measures emission power intensity of an LD 3 to correct drive current to the LD 3 so that the recording power shows a level according to setting and the linear speed dependent recording power setting device 22, the recording power correcting device 21 and the LD drive current controller 23 are operated independently of each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
