Claims

[Scope of utility model registration request]

A drive device for an optical pickup amplifier that drives an optical pickup in two directions perpendicular to the optical axis direction and the direction perpendicular to the optical axis, the end surfaces of which are magnetized in the optical axis direction and have the same polarity facing each other. a movable part that is movable integrally with the optical pickup, including a pair of magnets provided to a first drive coil wound around the first drive coil; a yoke disposed outside the first drive coil and facing the end surface of the plate; a second drive coil wound substantially perpendicular to the magnetic flux and the optical axis; and a second drive coil provided over at least a movement range of the movable part so as to be close to both end surfaces of the yoke in the optical axis direction. What is claimed is: 1. A drive device for an optical pickup, comprising: a sub-yoke;
