Abstract:
1. An adjustable optical pickup actuator with tilting, comprising: a yoke base; a magnetic-flux, further comprising a lens, said lens holder being located within the scope of said base, said magnetic-flux being suspended on two side with spring wires hanging on said yoke base; two focusing coils, located on two opposite sides of said lens holder, current in said focusing coils being perpendicular to the optical axis of said lens; a tilting coil, located on said magnetic-flux, current in said tilting coil being perpendicular to the optical axis of said lens, and being parallel to said current in said focusing coils; two tracking coils, located on two opposite sides of said magnetic-flux, current in said tracking coils being parallel to the optical axis of said lens; and four magnets, located at four corners of said yoke base for generating a closed magnetic-flux, said magnetic-flux, said focusing coils, said tilting coil and said tracking coils being located within the scope of said magnetic-flux.
