The present invention relates to an apparatus capable of optically recording information onto an information medium (1) by converging a light beam which is emitted from a first light source (6) and passes through a first beam-splitter (8) and a collimating lens (10) onto the information medium (1) using a convergence lens (12) and converging a light beam which is emitted from a second light source (7) and passes through a second beam-splitter (9) and a collimating lens (10) onto the information medium using a convergence lens (12). When visual information such as a title and an image relating to information recorded in the information layer (2) of the information medium (1) is recorded onto the visual information layer (5) of the information medium (1), the first light source (6) and the second light source (7) emit light simultaneously, thereby improving emission intensity. This enables changing the color of the visual information layer which is made by heat-sensitive recording materials, thereby improving a recording speed of the visual information. |
