Title:
DRAWING SYSTEM AND DRAWING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/210970
Kind Code:
A1
Abstract:
A drawing system according to one embodiment of the present invention comprises a light source unit and a scanning unit. The light source unit generates multiple laser beams including wavelengths that are different from each other and that correspond to absorption wavelengths of a photothermal converter contained in a recording medium. The scanning unit scans the laser beams over the surface of the recording medium in a state in which spots irradiated by the multiple laser beams are lined up at a predetermined spacing in a direction orthogonal to or obliquely intersecting the directions in which the laser beams are scanned.
