Information recording apparatus for thermosensitive medium

摘要

A recording apparatus for recording information in a thermosensitive medium (4) which has a photothermal conversion layer having a light wavelength absorption property and a coloring layer colored by the heat generated by the photothermal conversion layer comprises a first light source (1) that emits a light beam for writing information to a scanning position in a main scanning direction in the thermosensitive medium (4), and a second light source (7) that emits a light of lower energy density than the light beam emitted by the first light source (1) to the scanning position in the main scanning direction in the thermosensitive medium (4) or to the vicinity thereof. The first light source (1) and the second light source (7) emit lights having wavelengths within the range of the absorption property of the photothermal conversion layer respectively to form recording dots of one line in the main scanning direction in a noncontact manner with the thermosensitive medium (4).
