Folio Photonics Announces Great Leap Forward with Newly Patented Systems and Methods for Increasing Data Rate and Storage Density in Multi-Layer Optical Discs

February 7th, 2023

In a related announcement to the team's newest addition, Folio Photonics also unveiled today another great leap forward in the development of the first-ever enterprise-scale, immutable active archive solution. Folio has been awarded a United States Patent for “Systems and Methods for Increasing Data Rate and Storage Density in Multi-layer Optical Discs.”

The patent abstract states: “Systems and methods, e.g., optical apparatuses, for digital optical information storage systems that improve the speed, signal to noise, controllability, and data storage density for fluorescent and reflective multi-layer optical data storage media. The systems and methods include an optical system for a reading beam of a data channel from a moving single or multi-layer or otherwise 3-dimensional optical information storage medium that comprises at least one optical element characterized by restricting the field of view (FOV) of the reading beam on an associated image plane to 0.3 to 2 Airy disk diameters in a first direction.”

In lay terms, the novel inventions protected under this patent will deliver numerous benefits, including improved performance and ease of management of Folio Photonics’ multi-layer optical disc storage technology. In addition, newly enhanced signal strength relative to background noise will lead to higher throughput, lower latency and increased performance. And, allow the storage capacity potential of a Folio Photonics disc to dramatically increase.

“This patent plays a key role in enabling Folio Photonics' optical media to be used for data storage,” said Steve Santamaria, Folio Photonics. “This novel design and detection method will act as the basis for our optical pickup unit, which reads and writes data marks to our multi-layer media as part of the optical disc drive. Subsequently, by enabling end-users to use our storage media in this way, the patent allows for significant gains across cost-efficiency, accessibility, ease of deployment and archival duration period, which is essentially now in perpetuity.”

He continued, “It is by no means an understatement to say that designing a new optical pickup unit to work with nontraditional multi-layer media is the hardest part of new optical storage development, aside from creating the new media itself. Not only have we patented this design and its application, but we have also brought it to life on our optics bench. We have demonstrated this approach’s validity as it greatly contributed to our achieving reading/writing data to all layers of our disc.”

The innovations, which build on the Folio Photonics archive solution’s breakthrough cost, security and sustainability benefits, were invented by Folio Photonics’ Founder, Kenneth D. Singer, Ph.D. and COO/CTO, Irina Shiyanovskaya, Ph.D., together with Asher Sussman, and Thomas Milster, Professor of Optical Sciences and Young Sik Kim, Assistant Research Professor of Optical Sciences, both of whom are from the Wyant College of Optical Sciences at the University of Arizona.
