Publication number: 20160086628Abstract: Diffracted light generated by a recording medium in reproduction is largely blocked by a spatial filter because of a position shift of the recording medium. Thus, the light amount of the diffracted light converged onto an optical detector is reduced and a satisfactory level of a reproducing signal cannot be obtained. In addition, in recording, it is necessary to fix the position of the spatial filter in rays for removing unnecessary frequency components or the like in a light beam emitted from a light source. In actuators having at least two spatial filters, one spatial filter is mounted on an actuator driven along two or more axes and moves independently of another spatial filter, and the other spatial filter is fixed to a common one-axis actuator. Switching of the positions of the spatial filters is performed by the common one-axis actuator.Type: ApplicationFiled: May 22, 2013Publication date: March 24, 2016Inventors: Jiro HASHIZUME, Kazuyoshi YAMAZAKI, Seiichi KATOU, Katsuhiko KIMURA
