The pickup unit includes at least one bobbin (31,32) surrounding a yoke plate (14,15), upon which a first coil (31A,32A) is wound, and further transversely mounted coils (31X,31Y; 32X,32Y) attached to the first coil. The coils collectively control movement of the pickup unit (30) in tracking, focusing and tilt directions thereof. A further bobbin (36) connected to the slider (43) surrounds the yoke plate (14) and includes a further coil (36A) wound thereabout for driving the slider and the pickup unit radially of an associated optical disk (20).</p> |
