Abstract

PURPOSE:To improve the follow-up performance of focus control and tracking control by forming an optical system holding body by resin whose main component is diacetylene. CONSTITUTION:The objective lens holding body 1 is inserted into a supporting shaft 11 through a bearing and an objective lens 2 and a dead weight 12 having weight almost similar to that of the objective lens 2 to hold weight balance are fixed in the vicinity of the bearing. A focusing coil 3 is wound around the external peripheral part of the holding body 1, rectangular tracking coils 4a, 4b are fitted under the coil 3 and a magnetic circuit for generating a magnetic field is arranged so as to cross the coils 4a, 4b. The holding part 1 is formed by resin whose main component is diacetylene. Since the light-weight optical system holding body 1 excellent in electric insulating property and rigidity is used, the follow-up performance of focus control and tracking control can be improved.
