摘要 |
<P>PROBLEM TO BE SOLVED: To provide an optical pickup device using a unit to remove crosstalk in a multi-layered disk, and an optical recording/reproducing device. <P>SOLUTION: The optical pickup device for recording/reproducing data on a target recording layer of a disk having a plurality of recording layers includes: a light source; an optical path converting unit for converting the path of light emitted from the light source; a crosstalk removing unit having a reflection area for reflecting light incident from the optical path converting unit and a transmission area for transmitting the incident light, and inclined at a predetermined angle to the optical axis of the incident light to reflect the light reflected in the reflection area in a direction different from the incident direction of the incident light; an objective lens for focusing the incident light on the disk; and a photodetector for detecting the light reflected on the disk. <P>COPYRIGHT: (C)2010,JPO&INPIT |
