<P>PROBLEM TO BE SOLVED: To provide an optical pickup which can be easily miniaturized/thinned without damaging an electromagnetic performance and an optical performance. <P>SOLUTION: The optical pickup comprises: a movable member 11 where a plurality of objective lenses 12 and 13 are loaded at the center portion; a pair of coil blocks 20 provided on both side parts 11B of the movable member 11; two sets of magnets 31 arranged so as to flank the pair of coil blocks 20 respectively; support members 15 swingably supporting both side parts 11B of the movable member 11; and standing mirrors 32 and 33 facing the center portion 11A of the movable member 11. The coil block 20 includes a focusing coil 21 for driving the movable member 11 in a focusing direction F and a tracking coil 22 provided on an outer side of the focusing coil 21 for driving the movable member 11 in a radial direction R. The center portion 11A of the movable member 11 is thinner than both side parts 11B provided with the coil block 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
