Title: Mark A Arps: Innovator in Optical Storage Technology
Introduction
Mark A Arps is a notable inventor based in Woodbury, MN (US), recognized for his contributions to optical storage technology. He holds a total of 5 patents, showcasing his innovative approach to data storage solutions.
Latest Patents
One of his latest patents is for a dual-layer optical storage medium that features a partially reflecting layer made of amorphous selenium. This multi-layer optical storage medium consists of a transparent substrate, a partially reflective layer, a transparent spacer, and a highly reflective layer. The design includes one pattern of data pits on the substrate, adjacent to the partially reflective layer, and another pattern of pits on the spacer layer, adjacent to the highly reflective layer. The partially reflective layer is made of amorphous selenium (a-Se) and is characterized by an index of refraction with a real component, n, greater than 2.8 and an imaginary component, K, less than 0.01. This invention also encompasses optical data storage systems compatible with such media.
Another significant patent by Arps involves a dual-layer optical storage medium with a partially reflecting layer made of antimony sulfide. Similar to his previous invention, this multi-layer optical storage medium includes a transparent substrate, a partially reflective layer, a transparent spacer, and a highly reflective layer. The partially reflective layer may consist of antimony sulfide, such as antimony(III) sulfide, Sb2S3. This invention also includes optical data storage systems that are compatible with these media.
