Provided is an optical pickup device that compensates for an aberration caused by a beam splitter. When a beam of light is reflected from a disc and proceeds towards a beam splitter, the beam splitter is designed to allow the reflected beam to pass therethrough. However, the beam splitter can cause an astigmatism in the reflected beam due to diffraction. According to various aspects herein, an optical pickup device may include a compensation device that generates an inverse astigmatism to compensate for the astigmatism generated by the beam splitter.

Beam controlling method and optical pickup device for performing the method

Provided is an objective lens driving unit that prevents an electrical short circuit between very closely spaced second terminals in the objective lens driving unit. The objective lens driving unit is capable of being used in a slim-type optical disc drive.

Wire holder and wiring layers included in an objective lens driving unit

Provided are an objective lens driving unit that maintains the electrical connection between suspension wires and winding bosses. The objective lens driving unit includes a plurality of winding bosses disposed at a side of the frame, each having a projection formed at its end and extending in a direction in which a suspension wire extends.
