Title: The Innovations of Stefan Knappmann
Introduction
Stefan Knappmann is a notable inventor based in Rottweil, Germany. He has made significant contributions to the field of optical recording media, holding 2 patents that showcase his innovative approach to technology. His work has implications for both consumer electronics and data storage solutions.
Latest Patents
One of his latest patents is for an optical recording medium with write-once and rewritable properties. This invention describes a write-once optical recording medium that also possesses rewritable capabilities. The medium features a recording layer with at least a first and a second recording sublayer, which allows for the recording of information marks through the alloying of materials from these layers. The materials are specifically chosen to ensure that the alloyed material acts as a phase-change material, enabling the recording of additional data as phase changes occur.
Another significant patent by Knappmann is for an optical recording medium designed for retail activation. This modified ROM disk can only be played after undergoing an activation process. In this case, a portion of the reflective layer in the read-only area is replaced with a light-sensitive layer stack that alters its reflectivity when illuminated. This innovation also includes methods for producing such optical recording media, as well as techniques for initializing and activating them.
