IPC: G11B7/135
Filed: 1993-05-26
Abstract: PURPOSE:To provide a small sized optical pickup to satisfactorily perform recording and reproducing information on an optical disk by converting reflected light from the optical disk into two diffraction light beams diffracted in different directions at either angle of (2n+1) and pi/4, where (n) is an integer, to the polarizing direction of linear deflection from a light emitting element, having the same diffraction angle. CONSTITUTION:Return convergent light 15 converged by an objective lens 10 after reflecting on the disk 11 is converted by a hologram 8 into 1st and 2nd return diffracted light beams 16 and 17 having the same diffraction angle and diffracting in the opposite directions having angles of 45 deg. and 225 deg. to the polarizing direction of a semiconductor laser chip 2. Since the diffracting directions of these diffracted light beams 16 and 17 are different from each other by 180 deg., irrespective of the presence of a change of the polarization state due to the Kerr effect, the polarization state as to polarization separating parts 18 and 19 respectively of both diffracted light beams 16 and 17 is the same, so that an RF signal, a focus error signal and a tracking error signal can be obtained by this sensor shape and this circuit configuration.
