OPTICAL PICKUP ACTUATOR, OPTICAL PICKUP APPARATUS AND OPTICAL RECORD AND REGENERATION APPARATUS, MAKING OPTICAL AXIS OF OBJECT LENS IDENTICAL TO DRIVE AXIS OF MAGNETIC DRIVER AND ARRANGING FOCUSING COIL, TRACKING COIL AND TILT COIL SYMMETRICALLY

摘要

PURPOSE: An optical pickup actuator, an optical pickup apparatus and an optical record and regeneration apparatus are provided to make a conventional soldering process by separating a lens holder support from an electric wire and to assure system stability and a high precision control by preventing a sub resonance caused by an asymmetric shape of an optical pickup actuator. CONSTITUTION: The optical pickup actuator comprises a holder, a lens holder(120), a magnetic driver, a support member(140), and electric wires(W). The holder is formed on a side of a base. The lens holder(120) mounts an object lens. The magnetic driver includes a focusing coil(FC), a tracking coil(TC), a tilt coil and magnets(136,137) for driving the lens holder toward a focusing direction, a tracking direction and a tilt direction. The support member(140) makes one end be combined with the holder, and the other end be combined with the lens holder(120). The electric wires(W) is separated from the support member for supplying electricity for the coils(FC,TC).
