Abstract
A method used during the manufacturing of a device of an optical pickup device for bonding and fixing drive coils to a lens holder or other parts of a drive device. The optical pickup device has a lens holder and a magnetic drive device for driving the lens holder in a tracking direction and a focusing direction, the magnetic drive device having a permanent magnet and drive coils fixed to the lens holder. The method includes providing a fuse wire having a wire and a fuse coating covering the wire, pressing the fuse wire on the lens holder at a predetermined position, energizing the fuse wire in the pressed position to melt the fuse coating, and curing the melt fuse coating to bond and fix the fuse wire to the lens holder to form the drive coils. Alternatively, the fuse wire may be melt first and then pressed to the desired position of the lens holder. The current used for energizing the coil to melt the fuse coating or fuse film is much larger than drive currents used during normal operation of the optical pickup device.
