Title: Optical pickup device and optical disk recording-and- reproducing device
Inventor: TERAJIMA TAKAO
IPC: G11B7/095
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To correspond to optical disks having different kinds of substrates in thickness by differently using light sources and also to automatically correct a coma aberration caused by the difference in incident angle to an objective lens formed by a different light source in synchronization with the control of focusing. SOLUTION: The objective lens 3 is brought near to the optical disk 1b, since the optical disk 1b of thick substrate is different in position of a data- bearing surface in the z-direction from the optical disk 1a of thin substrate. So, an objective lens-driving means 9 moves the objective lens 3 toward the optical disk 1b and tilts the objective lens 3 in the direction of an arrow mark A. As shown in Figure 2, the optical axis 8b of the luminous flux heading for the objective lens 3 and the optical axis 31 of the objective lens 3 are oppositely inclined to each other to the perpendicular line on the face of the optical disk 1b, and for this reason a light spot with reduced aberration converges to the optical disk 1b by the actuation of the objective lens-driving means 9.
