Abstract
PURPOSE:To manufacture an apparatus at a low cost by making a center yoke through bisecting it beforehand and by inserting a non-magnetic resin plate having electrical insulating characteristics into a central cutting part and sticking said part thereto. CONSTITUTION:A linear motor magnetic circuit is composed of a permanent magnet 1, an outer yoke 2, and a center yoke 3 and equipped with a short ring 5 and a moving-coil 4 for a coil holder 6, and a light head detector for a compact disk is mounted on said holder 6. Then, said center yoke 3 is cut in two in the central part, a non-magnetic and electrical insulating resin plate or the like is inserted into the cut place and stuck to the center yoke 3 by resin, and a tube for the copper short ring 5 is firmly stick to the outer periphery of said center yoke 3 by a resin adhesive to be formed into an integral body. Thus, an apparatus can be made at a low cost by a simple processing device.
