PURPOSE: A rising-type slider of a disk pickup device for a disk drive is provided to combine wires where a lens is attached with a slide body so that the wires can vertically move, and to change a height of the lens according to a change of an electrical control signal to conduct a focusing control, thereby exactly controlling a focusing point. CONSTITUTION: A lens supporting element(30) is combined with an upper part of a slide body(10) so that the lens supporting element can vertically move, and supports a lens(20). An elastic element(40) elastically supports the lens supporting element(30) in downward direction. A coil(60) is installed on a lower side of the lens(20), and vertically drives the lens supporting element(30). Both sections of one pair of wires are inserted into both slide grooves(11) of the slide body(10) in the lens supporting element(30). The lens(20) is attached to a middle part of the one pair of the wires. |
