Abstract
A holographic data storage medium (1) has a polymer film which is set up as a storage layer (2) and whose surface structure can be changed locally by heating. The polymer film (2) is set up for the storage of holographic information via the local surface structure (6) of the polymer film (2). A reflective layer can be provided on the data storage medium.
Claims25
Holographic data storage medium, having a polymer film (2;
- 2′) which is set up as a storage layer and whose surface structure can be changed locally by heating and which is set up for the storage of holographic information via the local surface structure of the polymer film (2;
- 2′).
Use of a data storage medium, which has a polymer film (2;
- 2′) which is set up as a storage layer and whose surface structure can be changed locally by heating, as a holographic data storage medium (1;
- 1′), it being possible for holographic information to be stored via the local surface structure of the polymer film (2;
- 2′).
