摘要： PROBLEM TO BE SOLVED: To read information from an object information recording surface to be realized without fail by canceling a DC offset interfering with a signal for detecting a tracking signal. SOLUTION: In performing tracking servo with a 3 beam method, auxiliary light-receiving areas for D3-1, D3-2, D8-1, D8-2 are arranged. In the auxiliary light-receiving area, an image is formed by a reflecting light from the information recording surface which is different form the object information recording surface. A side beam as ±primary diffracted light is made incident on the light-receiving areas D3, D8 and D1, D10. Regarding a diffraction direction for a hologram 8, at both sides for the light-receiving areas D3, D8, the auxiliary light-receiving areas D3-1, D3-2, D8-1, and D8-2 are arranged. Because calculation for D8-(D8-1+D8-2) and D3-(D3-1+D3-2) is performed with an internal wiring, the DC offset can be canceled for D1+D3 for an RES signal used for DPP and D8+D10.

摘要： PROBLEM TO BE SOLVED: To provide an optical pickup device and a semiconductor laser device in which reduction of the light utilization efficiency of a laser beam emitted from a semiconductor laser element can be suppressed. SOLUTION: When a laser beam A which is emitted from a laser element 32 for the DVD and of which the polarization direction is perpendicular to the direction of the groove of a polarization grating 23 is made incident on the polarization grating 23, the polarization grating 23 does not diffract the laser beam but transmit it as 0 order diffraction light A0. Therefore, all laser beams emitted from the laser element 32 for the DVD can be used for reading the information signal of the DVD and detection of FES, TES. Thereby, reduction of the light utilization efficiency caused by the diffraction of the grating 3 used fro detecting TES of a CD in a conventional optical pickup device 1 can be suppressed.
