| Abstract(in English) | We propose an integrated catadioptric pick-up with ferrofluid cooling structure for optical disks like DVD. An objective lens and a holographic optical element are integrated into a single optical element, called holographic catadioptric lens. This enables the integration of all optical components including a laser diode into a moving part of the pick-up. The gaps between the moving part and the fixed optical base are filled with a high-thermal-conductivity ferrofluid, which is supported by magnetic field. With this configuration, Joule heat generated in the moving part is effectively dissipated to the optical base through the ferrofluid without sacrificing the motion of the moving part for its fluidity. The optical characteristics and the cooling performances are applicable to the future extremely small optical disk systems. |
