Filed: 2001-07-06
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup device enabling reproduction of recording information of two types of recording mediums each having a different recording density, by using one only laser diode (wavelength 780 nm). SOLUTION: Between a laser light source 2 and a beam splitter 9, there is installed a liquid crystal element 33 as a means for rotating a plane of polarization. A light beam emitted from the laser light source 2 passes through the liquid crystal element 33 and the beam splitter 9 and parallelized by a collimator lens 14. This parallelized light is made incident on a first light beam selecting means 3 and reflected on a first reflection area 4 which is a flat face, or on a second reflection area 7 which is a recessed face, and this reflected light is made to enter a super-resolution shielding means 31 as a second light beam selecting means.
