| 英文摘要 | PURPOSE:To realize the miniaturization, light weight, and low power consumption of an optical pickup by performing focusing servo, etc., by fixing the position of an objective lens, setting movably and driving a main part in which a semiconductor laser, an optical detector, and an optical device, etc., are made into integration. CONSTITUTION:The title device is constituted in such a way that the objective lens 9 is fixed, and an integrated body 6 is movable, and a magnet 7 is fixed on the bottom plane of the integrated body 6, and the focusing drive of the integrated body 6 can be performed by a coil 8 with a voice coil system via the magnet 7. And the sum of the weight of the integrated body 6 and the magnet 7 is less than that of the objective lens 9. Thus, since focusing is performed by driving the integrated body 6 lighter than the objective lens 9, the power consumption for the focusing can be reduced to minimum. |
