An information recording method for recording desired information, wherein a control circuit (150) identifies a characteristic of light corresponding to information to be recorded, in accordance with table data stored in a table memory (151), indicating a corresponding relationship between the information to be recorded and the wavelength of the light and selects a light emitting material which emits the identified characteristic of the light in response to energy (electricity or light) supplied thereto, and a recording head (110) forms a light emitting element by supplying the light emitting material on a substrate (10) of a recording medium. Furthermore, energy is supplied to the recording medium on which the information is written so that the light emitting material emits light, the characteristic of the light is identified and the information is reproduced in accordance with the identified characteristic. The security of the information is enhanced with a new and easy method of information recording. <IMAGE> |
