发明名称 Information reproduction device
摘要 An information reproducing apparatus (1) is provided with: a detecting device (11) for irradiating an information. recording medium with laser light (LB) and detecting reflected light as a detection signal, the information recording medium including a first recording layer (L0) and a second recording layer (L1); a high pass filter (14) for performing a filtering process on the detected detection signal; and a reproducing device (15, 16) for performing a reproduction process of the filtered detection signal to reproduce the data, the high pass filter attenuates a fluctuation component of the detection signal, caused by a relative eccentricity between the first recording layer and the second recording layer, by a first attenuation amount (34dB) or more.
