Patent number: 7151623Abstract: In an example holographic data storage medium, which has a polymer film which serves as a storage layer and can be changed locally by heating, the polymer film is set up as a top layer of the data storage medium. Arranged underneath the polymer film is an absorber layer which has an absorber dye. The absorber dye is set up to at least partly absorb a write beam serving to put information in and to discharge the heat produced in the process at least partly locally to the polymer film. In an advantageous refinement of the example data storage medium, there is an adhesive layer underneath the absorber layer and a partly transparent reflective layer between the polymer film and the absorber layer.Type: GrantFiled: February 25, 2002Date of Patent: December 19, 2006Assignee: Tesa Scribos GmbHInventors: Jorn Leiber, Anna Blazejewski, Steffen Noehte, Stefan Stadler, Christoph Dietrich, Matthias Gerspach

Patent number: 7126729Abstract: The invention relates to a method of providing an article with identifying information, in which a hologram is provided from which at least first and second hologram patterns separated physically from each other can be reproduced. In this case, provision is made for the hologram to be produced in such a way that the first and second hologram patterns can generally be reproduced in one and the same direction but in different planes.Type: GrantFiled: February 1, 2002Date of Patent: October 24, 2006Assignee: Tesa Scribos GmbHInventors: Steffen Noehte, Matthias Gerspach, Christoph Dietrich, Stefan Borgsmüller, Anna Blazejewski, Stefan Stadler, Jörn Leiber
