<P>PROBLEM TO BE SOLVED: To provide a method for reducing the number of terminals, which become interfaces with an optical disk device, in the three-wavelength type optical pickup of the optical disk device which generates and processes both of a red laser beam and a blue laser beam. <P>SOLUTION: Terminals are shared by the PC output of an ACU detecting whether or not an optical pickup is positioned at a prescribed position when an optical device is powered on or reset and the output of an FMIC detecting the power of a generated laser beam; or the terminals are shared by the PS output of an ACU and the output of an OEIC converting the catoptric light of the optical disk into an electric signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
