摘要： An information recording/reproducing apparatus of the invention is equipped with an objective lens, a light source and a variable optical element having a grating which demonstrates a piezo-electric effect by means of an electric field. The light source emits and irradiates a laser beam onto the grating to generate a 0th order diffraction beam and +/− 1st order diffraction beams in accordance with first order diffraction efficiency, and the objective lens converges the 0th diffraction beam and +/− 1st order diffraction beams which are irradiated onto an information recording medium for the purpose of information recording or information reproducing. By controlling an electric field applied to the grating, the first order diffraction efficiency of the grating is adjusted, whereby light beams are generated which have power levels appropriate for various kinds of information recording media.

摘要： A first thermal buffer layer and a second thermal buffer layer are arranged between a recording medium and an actuator structure. The heat conductivity of the first thermal buffer layer is set low and the heat conductivity of the second thermal buffer layer is set high. Most of the heat generated from a coil wiring of the actuator structure is blocked by the first thermal buffer layer, and heat leaked from the first thermal buffer layer is diffused by the second thermal buffer layer. Temperature distribution on the recording medium is made uniform, and thus, a configuration wherein the recording medium and the actuator structure are placed one over another can be provided, information reading accuracy or information recording stability can be improved and the sizes of an information storage device can be reduced.
