<P>PROBLEM TO BE SOLVED: To achieve an objective lens driving device correcting a plurality of aberrations of an optical pickup and having satisfactory dynamic characteristics by properly arranging elastic supports connecting a fixing part and a movable part. <P>SOLUTION: The objective lens driving device includes the fixing part 2, the movable part 3 supported on the fixing part 2 with the elastic supports 4a-4h also operating as an electricity supply passage, an objective lens 10 mounted on the movable part 3, focusing coils 6y, 7y, tracking coils 6x, 7x, a liquid crystal element 20, and a driving IC 9. In the driving IC 9, power sources P1, P2, a serial data signal S5, and a serial clock signal S6 are input through the elastic supports 4e-4h to drive the liquid crystal element 20. Thus, the plurality of aberrations can be corrected, and the objective lens driving device having the satisfactory dynamic characteristics can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
