    摘要： A video image data compression archiver is composed of an encoder and an encoder controller. The encoder compresses non-compressed video image data to generate compressed video image data. The encoder controller is connected to said encoder to control a frame size, a frame rate, and an average bit rate of said compressed video image data in response to at least one parameter selected from a group consisting of a number of frames of said non-compressed video image data, a recording time of said non-compressed video image data, and a free area of a recording medium for recording said compressed video image data.

    摘要： Provided are an optical device, optically assisted magnetic recording head and optically assisted magnetic recording apparatus that effectively emit the introduced light, from the apex portion of a waveguide. The optical device includes: an optical element having a substantially parabolic outline which contains a side surface and the apex portion with a light-emitting surface; a light guiding unit for forming a light spot on the core layer; and a light introducing section provided on the core layer at the position at which the light spot is formed. The light introduced into the core layer travels substantially parallel to the axis of the parabola, and is reflected by the side surface so as to be converged at the focal point of the parabola and is then emitted from the apex portion. The position of the point where the light intensity is greatest in the light spot is deviated from the axis.

    摘要： Provided is an optical device configured to makes it possible to enhance use efficiency of light. An optical device is provided with an optical element to deflect incident light and a fixation member on which the optical element is fixed. The optical element includes a reflective surface and a diffraction grating surface that deflects the incident light. The optical element is fixed on the fixation member to restrain displacement in accordance with temperature changes at portions thereof other than the reflective surface and the diffracting grating surface in such a condition that displacement is caused without restraint be temperature changes at the reflective surface and the diffraction grating surface. A change of the incident light in the deflection angle due to an inclination change by the reflective surface and the diffracting grating surface is suppressed by a change in a diffraction angle due to a periodical change in the diffraction grating by the displacement of the diffraction grating surface.
