In a method of entering information into an optically writable and readable data storage medium having a polymer film which can be changed locally by heating in order to store information and to which there is assigned an absorber dye ( 34 ) which is set up to absorb a write beam ( 36 ), at least partly, and to transfer the heat produced in the process, at least partly, locally to the polymer film, first of all the absorber dye is heated locally in a predetermined region of the polymer film in accordance with the information to be entered, specifically by means of a pulsed write beam ( 36 ). After that, the absorption properties of the absorber dye ( 34 ) are changed by means of light, to be specific preferably by means of a fixing beam ( 37 ) which bleaches ( 38 ) the absorber dye ( 34 ) in the written region of the polymer film. |
