Optical pickup comprising a heat-insulating material

Abstract

An optical pickup includes an object lens; a lens holder for holding the object lens; a visco-elastic suspender for suspending the lens holder so as to be movable in a focusing direction and a tracking direction; a driving section for driving the lens holder in the focusing direction and the tracking direction, the driving section including a magnet, a yoke and a driving coil provided on the lens holder. The magnet and the yoke form a magnetic circuit. A heat-insulating area is located between the object lens and the driving coil, and the heat-insulating area includes a heat-insulating material which has a thermal conductivity lower than that of the lens holder.
