Title: Optical pickup and optical disk device
Inventor: ITONAGA MAKOTO
IPC: G11B7/135
Filed: 1993-11-26
Abstract: PURPOSE:To reduce the effect of a tangential tilt and to improve the degree of a total allowance by imparting previously aberrations corresponding to the tilt of a tangential direction to plural beams and irradiating a disk with these beams and a 0-order diffracted light beam. CONSTITUTION:A diffraction element 16 is made to be a grating pattern whose interval is widen and whose curvature is increased, for example, from a center toward an edge part. Thus, + or -1st-order diffracted light beams having coma aberrations are obtained. The grating pattern is determined by imparting a diffraction direction, the dimension of the coma aberration and the light quantity ratio of diffracted light beams. Since conjugate diffracted light beams with a +1st-order light beam and a -1st-order light beam are generated, the pattern becomes symmetric with respect to the spot of + or -1st-order diffracted light beams converged on a disk 22. Further, the spot of the 0-order diffracted light beam becomes an aberration-free spot because it is not subjected to a phase-shifting by the diffraction element 16.
