Title: Optical pickup, optical disk device, and optical element
Inventor: ONISHI KUNIKAZU
IPC: G11B7/135
Filed: 2007-09-03
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that sufficient performance of an optical pickup cannot be secured because during recording/reproducing to/from a two-layer disk, reflected light from a layer other than a recording/reproducing target layer interferes as unnecessary light with signal light on the light receiving surface of a photodetector, causing superimposition of a large fluctuation component or a noise component on a detected signal.  <P>SOLUTION: A first unnecessary light elimination optical element having highly sensitive ray advancing angle selectivity and a second unnecessary light elimination optical element having a light shielding zone only in a small area near an optical axis are arranged in a return optical path. Thus, only unnecessary beams are almost completely eliminated selectively from the light receiving surface. An optical pickup and an optical disk device having high reliability are provided with almost no reduction in quality and light utilization efficiency of signal reproducing light.  <P>COPYRIGHT: (C)2009,JPO&INPIT
