Abstract
In a method of writing information in a data storage medium comprising an optical information medium which has a polymer carrier (1), atoms and/or molecules (4) that change the refractive index are introduced into the polymer carrier (1), at individual locations associated with information units, as a function of the information to be entered.

A method of writing information in a data storage medium comprising an optical information medium which has a polymer carrier, the method comprising introducing atoms and/or molecules that change the refractive index into the polymer carrier, at locations associated with individual information units, as a function of the information to be entered.
A data storage medium, comprising an optical information medium with entered information, which has a polymer carrier, the polymer carrier containing atoms and/or molecules that change the refractive index, at locations associated with individual information units, as a function of the entered information.
A data storage medium, comprising an optical information medium, which has a polymer carrier, the polymer carrier being provided with a layer which contains atoms and/or molecules that change the refractive index and which can be diffused into the polymer carrier by means of local heating.
A data storage method comprising:
- providing an optical information medium comprising a polymer carrier, and
- storing data by changing the optical properties of the polymer carrier, wherein the optical properties are changed by selectively introducing atoms and/or molecules into the polymer carrier.
