  • Recording medium and recording device
    Patent number: 11294306
    Abstract: A recording medium of an embodiment includes a base material; a first color development layer that is located on the base material and absorbs light of a given wavelength to develop color; a second color development layer that is located closer to an incident side of the light than the first color development layer, transmits visible light and the light, and develops a color by heat; and a photothermal conversion layer that is located closer to an incident side of the light than the second color development layer intended to develop a color, transmits the visible light, and absorbs the light to photo-thermally convert the light into the heat.

  • Manufacturing method for optical head device and optical head device
    Patent number: 7283433
    Abstract: A manufacturing method for an optical head device includes integrating at least a plurality of light sources and a plurality of diffraction elements with each other as an optical module, adjusting a relative positional relationship of the plurality of diffraction elements each other on the optical module, and then adjusting spot positions of the sub-beams on the optical recording medium by adjusting the entire optical module on the device frame. After that, the optical module is fixed on the device frame.
