Optical component-driving device for optical pickup.

摘要

An optical component-driving device for driving an optical component along a tracking axis and/or a focusing axis includes a magnet (14), a yoke (15) and a coil (13). The coil is fixed to a moveable member (12) which houses the optical component to be moved (11). The coil is disposed in spaced, opposed relation to two opposite polarity surfaces arranged adjacent and planar to one another and disposed in the direction of tracking and/or focusing. The first polarity surface is provided by the facing surface of a polarized magnet (14). The second polarity surface is provided by one end face of a yoke (15), the other end face of which abuts the opposite polarity backing surface of the magnet.
