摘要： In an optical pickup for use in an optical disc device, wire rods are wound directly around a lens-coil holder to make tracking coils and focus coils. The lens-coil holder is divided into three holders, one of which holds an optical lens thereon and has on its sides wire-winding protrusions for wiring wire rods therearound to make tracking coils. The remaining holders have focus coils that are wound therearound. Alternatively, the lens-coil holder is divided into two holders, one of which has on its sides wire-winding protrusions for wiring wire rods therearound to make tracking coils. The remaining holder holds an optical lens thereon and has focus coils that are wound therearound. The lens-coil holder has a cavity for letting pass through a laser beam emitted in parallel to an optical disc surface.

摘要： Provided is a reliable optical pick-up which can prevent deterioration of a performance of a component, shortening of a service life or malfunctioning due to heat generation of an laser driver IC, wherein a metallic pattern is provided on a flexible printed board, having an area wider than the external shape of the laser driver IC and having an exposed outer surface, and made of the same material as that of a wiring pattern. It is preferable to bent the flexible printed board in a mounting part for the laser driver IC so that the metallic pattern is faced to and superposed with a surface of the flexible printed board on the side remote from the surface on which the laser driver IC is mounted.
