Patent ID: 8886025

Claim:
A heating apparatus that heats an elongated film material by irradiating the film material with a laser beam in manufacture of a film-form recording medium, said heating apparatus comprising: a film feed mechanism having a film contact surface that contacts with one surface of the film material, the film feed mechanism being configured to move the film material mounted thereon in a longitudinal direction of the film material; a laser light source; a laser irradiation component disposed opposite the film contact surface, the laser irradiation component being configured to emit a laser beam from the laser light source toward the film contact surface; and a laser controller configured to control emission of the laser beam, wherein the film contact surface includes a first contact surface and second contact surfaces, a material forming the first contact surface having a different thermal conductivity from a material forming the second contact surfaces, the second contact surfaces are disposed at positions that come into contact with ends of the film material in a width direction that is perpendicular to the longitudinal direction, the first contact surface is disposed between the second contact surfaces, and the material forming the first contact surface has a lower thermal conductivity than the material forming the second contact surface.
