Title: Gerhard Trippel: Innovator in Optical Storage Technologies
Introduction
Gerhard Trippel is a notable inventor based in Sindelfingen, Germany. He has made significant contributions to the field of optical storage technologies, holding a total of 13 patents. His work focuses on innovative manufacturing processes and structures that enhance the performance and reliability of optical disks.
Latest Patents
Trippel's latest patents include a manufacturing process for grooved substrates and multilayer structures. This invention involves a series of major process steps, including spin coating a supporting plate with a dissolved material to form a soft layer. Grooves are then stamped into this soft layer, creating a structured layer that reflects the negative image of the stamp. The structured soft layer is subsequently hardened through thermal treatment. The dissolved material used in this process contains polymeric organometal compounds, including polymer siloxane and/or polymer silicates. In one embodiment, the structured soft layer serves as a dielectric layer, incorporating various combinations of oxides such as SiO₂, La₂O₃, PbO, and TiO₂. The multilayer structure is completed with a magneto-optic layer, a reflector layer, and a passivation layer.
Another significant patent is for a system designed for stamping optical storage disks. This invention features a glass substrate into which guide tracks for servo-controlling focused light beams are directly stamped using a hot stamp process. After stamping, the glass substrate undergoes thermal quenching to enhance its breaking resistance. To ensure uniform guide tracks across the entire surface, flexible stamp stencils are employed, which can change curvature through hydro-static pressure. The stamp stencils are made from monocristalline silicon disks or metal disks, structured through photolithographic processes.
