Abstract

Provided is a method for manufacturing an optical pickup device, which has an aberration correcting means that performs highly accurate and high-speed aberration correction and suitably records and/or reproduces information. Such optical pickup device is also provided. A reference table (B) of a drive unit (CU) is provided with reference surfaces (P1, P2) parallel to guide shafts (GS, DS) which guide an optical element holder (LHD2) in an optical axis direction. The reference table arranges the optical element (L3) on the optical element holder (LHD2) so that a center mark (CM) put on the optical surface of the optical element (L3) is in aprescribed relationship with the reference surfaces (P1, P2) of the reference table (B). The reference surfaces (P1, P2) of the reference table (B) of the drive unit (CU) whereupon the optical element (L3) is arranged are fixed by having them abut to the reference surface of the optical pickup device. Thus, the optical axis of the light source and the optical axis of the optical element (L3) are easily accorded with each other.
