摘要

It is the optical disc drive device provided with the optical pickup device and an optical pickup apparatus including the optical pickup actuator, the optical pickup actuator is disclosed. The optical pickup actuator as disclosed is, there is an objective lens for focusing the light onto the optical disc is mounted, and a plurality of driving magnets interacts with the current flowing through the blades and the coil which the coil is wound to generate an electromagnetic force that drives the blade in a predetermined direction, to block leakage magnetic flux of the drive magnet comprises a base provided with a magnetic shield is arranged so that at least one drive magnet and the driven magnet of the same polarity opposed to each other. By removing part resonance in the focusing direction can improve the dynamic characteristics of the optical pickup actuator, an optical pickup device and optical disk drive apparatus having the same.
