Filed: 2002-07-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical pickup device which can stably output a signal including information required for position control of an objective lens.  <P>SOLUTION: Luminous flux emitted from a light source is converged on a recording plane of an information recording medium 15 through an objective lens 60.

A signal including position information relating to the optical axis direction of the objective lens is outputted from the optical detector. Since the quantity of transmission light of return luminous flux is adjusted in accordance with incident angle dependency of diffraction efficiency by the filter, return luminous flux in which an error due to incident angle dependency is reduced is received in the optical detector. And, consequently, a plurality of output signals from the optical detector become signals in which an error due to incident angle dependency is reduced. Thereby, a signal including position information relating to the optical axis direction of the objective lens can be stably outputted.  <P>COPYRIGHT: (C)2004,JPO
