<P>PROBLEM TO BE SOLVED: To attain miniaturization and to improve precision of control of output to a light emitting element. <P>SOLUTION: This system is provided with: the light emitting element 11; an optical path changing body 12 which reflects a part of laser beams emitted from the light emitting element to lead it to a disk-like recording medium 100, transmits not-reflected laser beams, and emits the transmitted laser beams from its optical path changing surface 12b; a light receiving element 15 for receiving the laser beams reflected by the disk-like recording medium; a reflection body 16 for reflecting the laser beams emitted from the optical path changing surface; an output control element 17 which receives the laser beams reflected by the reflection body, detects the output of the received laser beams, and controls the output of the light emitting element on the basis of the detected result; and a loading part 19 for loading the light emitting element, the optical path changing body and the output control element. <P>COPYRIGHT: (C)2003,JPO |
