<p>An optical pickup actuator, an optical pickup employing the optical pickup actuator, and an optical disc drive apparatus employing the optical pickup are provided. The optical pickup actuator includes a blade (37) on which an objective lens (39) for condensing light onto an optical disc is mounted, and in which coils (32,36) are wound, and a base (35) which includes a plurality of driving magnets (31a,31b), which interact with current flowing through the coils (32,36), to generate force that drives the blade (37) in a predetermined direction and a shielding magnet (40), which is arranged opposite to and has the same polarity as at least one of the driving magnets (31a,31b), to block leakage magnetic flux from the driving magnets (31a,31b).</p> |
