Abstract
A drawing method according to an embodiment of the present disclosure includes, when performing drawing on a thermal recording medium that includes a light-transmitting member above a recording layer, obtaining information regarding the light-transmitting member, predicting an optical axis deviation of a laser beam in the recording layer from the information regarding the light-transmitting member, and calculating a correction amount from a result of the prediction of the optical axis deviation.
Claims20
A drawing method used when performing drawing on a thermal recording medium that includes a light-transmitting member above a recording layer, the drawing method comprising:
- obtaining information regarding the light-transmitting member, wherein the information regarding the light-transmitting member comprises a surface shape of the light-transmitting member, and wherein the surface shape is not flat;
- predicting an optical axis deviation of a laser beam in the recording layer from the information regarding the light-transmitting member;
- and
- calculating a correction amount from a result of the predicting of the optical axis deviation.
An erasing method used when erasing an image from a thermal recording medium that includes a light-transmitting member above a recording layer, the erasing method comprising:
- obtaining information regarding the light-transmitting member, wherein the information regarding the light-transmitting member comprises a surface shape of the light-transmitting member, and wherein the surface shape is not flat;
- predicting an optical axis deviation of a laser beam in the recording layer from the information regarding the light-transmitting member;
- and
- calculating a correction amount from a result of the predicting of the optical axis deviation.
A drawing apparatus, comprising:
- a light source section that emits a laser beam;
- a scanner section that performs scanning on a thermal recording medium with the laser beam emitted from the light source section, the thermal recording medium including a light-transmitting member above a recording layer, wherein the recording layer comprises three layers each having color development tones different from each other;
- a reception section that obtains information regarding the light-transmitting member;
- and
- a correction section that predicts, from the information regarding the light-transmitting member, an optical axis deviation of the laser beam in the recording layer and calculates a correction amount from a result of the prediction, the information being obtained by the reception section, and the laser beam being transmitted through the light-transmitting member.
