Abstract: A lens driving device and an optical pickup device with the same are provided to move a lens group in an optical axis direction to efficiently perform at least one of a zoom function, a focus adjustment function, and a correction function of a spherical aberration. A lens carriage(100) mounts a lens group(110). A guide member having a pair of guide shafts(201,202) guides the lens carriage(100) to be moved in an optical axis direction. A driving member(300) moves the lens carriage(100). A magnetic member mutually combines the lens carriage(100) with the driving member(300) in the optical axis direction by magnetic force. The relative movement of the lens carriage(100) and the driving member is not restrained on a virtual plane vertical to an optical axis.

이 개시된 광자기헤드는 슬라이더가 광이 투과되는 투명재질로 이루어지고, 광자기 기록매체에 대면되는 슬라이더의 일면에 나선형 구조로 적층 형성된 적어도 하나의 코일층과 코일층을 덮어서 보호하며 그 코일층의 인접한 부위들 사이를 전기적으로 절연시키는 절연층과 코일층 및 절연층 중심부에 입사광이 투과할 수 있도록 투명물질로 이루어진 투명영역을 구비한 코일부재와, 광자기 기록매체에 대면되는 슬라이더 일면의 소정 위치에 도금에 의해 형성된 에어베어링과, 슬라이더에 마련되어 입사광을 집속시켜 광자기 기록매체에 광스폿을 형성시키는 집속수단을 포함한다.
이러한 광자기헤드는 슬라이더가 되는 투명 기판 상에 그 중심부에 광이 투과할 수 있는 투명영역을 갖는 코일부재와 에어베어링 부분이 반도체 제조 공정과 같은 미세 선폭 가공 공정을 통해 일괄적으로 제작 가능한 구조를 가지므로, 종래와는 달리 코일을 메사에 끼운 다음 슬라이더에 접착시키는 공정이 불필요하여 제작이 쉽고 소형화가 가능하다.-

Each of the magnets is asymmetrically divided into upper and lower parts by a horizontal magnetizing gap(G1) in the horizontal direction, wherein the horizontal magnetizing gap is positioned higher than the center of the magnet. The upper part is asymmetrically divided into two parts again by a first vertical magnetizing gap(G2) biased to the right side. The lower part is asymmetrically divided into two parts by a second vertical magnetizing gap(G3) biased to the left side. Such divided four parts are alternately magnetized with N and S poles.
