Abstract

An object of the invention is to prevent damage or performance degradation of an optical component constituting a second optical system, and suppress degradation of the recording/reproducing performance of an optical pickup device. A first laser light source 1 emits a first light beam having a first wavelength. A first optical system 17 guides the first light beam to be emitted from the first laser light source 1 to a first optical disc. A DVD integration unit 11 emits a second light beam having a second wavelength different from the first wavelength. A second optical system 18 guides the second light beam to be emitted from the DVD integration unit 11 to a second optical disc different from the first optical disc in recording density. A filter 20 is disposed at a position capable of blocking incidence of an unwanted light beam having the first wavelength derived from the first optical system 17 into an optical component constituting the second optical system 18 to block the first light beam having the first wavelength.
