Claims

[Scope of utility model registration request]

(1) A substrate having a support shaft provided at the apex position of a triangle and two permanent magnets installed at both ends of the base with opposite polarity and a non-magnetic member at the base, and a base plate that rotates on the support. a rotary bearing including a tracking coil that is freely pivoted and arranged close to the upper plane of the two permanent magnets;
The rotary bearing is mounted as a shaft with a key and a keyway, and a focus lens is disposed on one side from the center of the shaft, and is disposed on the outer periphery of the two permanent magnets at a position lower than the top surface on the other side. What is claimed is: 1. An actuator for an optical pickup comprising: a holding member having focus coils having opposite current directions; and an elastic member elastically holding the holding member to a substrate.
