First Multi-Terabyte Optical Storage Solution Compatible with Existing CD and DVD Formats
Call/Recall Inc. has announced the availability of licensing for its patented 2-photon recorded 3D optical storage technology. The latter is claimed to provide 40 times the capacity of Blu-ray and over 200 times the capacity of DVD optical storage technology.
The innovative optical storage technology is based on the work of company co-founder, Dr. Peter Rentzepis. A former head of Bell Laboratories, Rentzepis is a world-renowned scientist who has authored approximately 85 patents; his innovations are reportedly cited by many of the world’s top optical technology providers, including IBM, Panasonic and Hitachi.
Call/Recall is recording a ITB disk and has established a product roadmap delivering solutions capable of storing multiple terabytes of information per disk. The versatile 2-photon 3D technology can apparently be applied to solutions such as a 100+ terabyte optical library using DVD-size disk for enterprise data storage, or a 1-inch diameter 50 GB disk for consumer electronics devices such as cell phones, portable media players and game systems. Call/Recall says that, using its technology, manufacturers of consumer electronics devices as well as large-scale enterprise and government customers will be able to store and manage more data in less space while reducing cost and improving overall I/O performance.
A Growing Need
According to a 2003 report* from UC Berkeley’s School of Information Management and Systems, 5 exabytes of new information – the equivalent of 37,000 new libraries the size of the Library of Congress, or about 30 feet of books for each of the 6.3 billion people on earth – was created and stored in 2002. The global rate of data growth exceeds 30 percent annually, largely due to the increased use and sharing of digital content such as video, audio, gaming, electronic messaging, and the vast amounts of data created by both the public and private sector.
“Growing stockpiles of unstructured data are presenting end users with a new set of IT challenges, not just from a sheer capacity standpoint but also in terms of data access, management and cost,” says Heidi Biggar, an analyst with the Enterprise Strategy Group. “Advances in optical technologies, such as Call/Recall’s 2-photon 3D technology which promises to offer multiple terabyte data capacities and significantly faster data access than tape, hold new promise for users as they look to build more efficient and effective archives.”
The Core Technology
Call/Recall’s innovative optical storage technology utilizes a 2-photon recording process to record bits in a three-dimensional volume in a disk. Multiple layers of information can be stored within the 3D volume with less than a 10-micron layer of separation, effectively allowing the equivalent of 250 conventional DVD layers to be put onto one DVD. Projected layer densities reach High-Def formats allowing a roadmap to increase capacities by 5X.
Another key benefit of Call/Recall’s optical systems technology is said to be its use of affordable, commercially available, off-the-shelf components. This approach allows optical hardware manufacturers to extend the roadmap of their existing technologies, such as DVD and Blu-ray Disc, while maintaining backward compatibility with their installed base. Additionally, other key components are designed as molded/replicated parts, enabling very low-cost production on industry-standard production lines.
“Moore’s Law states that processing power doubles every 18-24 months, and that law applies to the data storage industry as well as to the semiconductor industry,” said Wayne Yamamoto, CEO, Call/Recall. “Government agencies, health care providers, entertainment companies, large corporations, and consumer products manufacturers must find a way to manage vast amounts of data economically, securely and seamlessly. By licensing Call/Recall’s breakthrough 2-photon recorded 3D optical storage technology, companies can rum widely available storage media into high capacity optical disk solutions, at a reasonable cost.”
At present, the technology is currently write-once but the company is working on read-write. Of great interest is data’recording throughput. Call/Recall is reporting approximate 100MB/sec I/O rates, which it believes can rise to 500MB/sec – five times faster than InPhase’s holographic disk. If it can also achieve backwards compatibility something not in any of the holographies players plans – this will indeed be a formidable technology.
