Optical Drive Technologies
Before working at Optics for Hire, several of our engineers worked on optical drive technologies. Starting in the late 1970s, they led and worked on programs creating equivalents of the laser disc, CD, and CDR formats. These were commercialized in the former USSR.
In the late 1990s, these same engineers worked on multi layer optical media drives for the former Constellation 3D. We have continued to work on optical data storage systems, most recently with Holigraphic data storage and the LaserCard format.
In the list below, some of the key technologies developed by the optical design team are described and projects from the last 30 years are listed.
