<P>PROBLEM TO BE SOLVED: To provide an optical pickup device that realize compatibility with an optical disk having a different track pitch. <P>SOLUTION: A plunger 120 is fixed on a feed gear 102. The tip end of a plunger pin 120a is engaged with a metallic fixture 124. Between the plunger 120 body and the metallic fixture 124, a compression spring 122 is installed around the plunger pin 120a as the center. When driving force for pulling the plunger pin 120a is imparted to the plunger 120, an angle adjusting pin 104 is brought to a 104a position in an angle adjusting hole 106, with the adjusting angle set at α. When no driving force is imparted to the plunger 120, drawing force is actuated by the compression spring 122, bringing the angle adjusting pin 104 to a 104b position in the angle adjusting hole 106, with the adjusting angle set at β. In other words, a side spot position can be controlled by pulling or not pulling the plunger pin 120a in accordance with the track pitch of an optical disk PD. <P>COPYRIGHT: (C)2003,JPO |
