The inventive data memory (1) has an optically writeable and readable information carrier, which has a polymer film (11) whose refractive index can be locally altered by heating. An absorber is assigned to the polymer film (11) and is disposed for at least partially absorbing a write beam and for transferring, in an at least partially local manner, the heat generated thereby to the polymer film (11). The absorber is oriented in order to preferably absorb light with a polarization direction that is matched to the orientation of the absorber.
