Seagate Sees The Future: Storing The U.S. Library Of Congress On A 50-Cent Coin

Seagate Technology (NYSE: STX) will present research findings pointing toward data storage densities of 50 terabits per square inch or more at the American Physical Society (APS) conference on March 25. At 50 terabits per square inch densities, over 3.5 million high-resolution photos, 2,800 audio CDs, 1,600 hours of television, or the entire printed collection of the U.S. Library of Congress could be stored onto recording media about the size of a single coin, such as a half dollar (30.61mm). Seagate's research team is currently developing the technology, called Heat Assisted Magnetic Recording (HAMR), which is expected to enable these ultra-high storage densities.

Dr. Terry McDaniel, Seagate recording physicist and APS member, will give the presentation entitled, "Ultimate Limits to Thermally Assisted Magnetic Recording." The presentation is part of the APS session V6 series, "Ultimate Limits to Data Storage." A session abstract can be found at the APS site, This work was performed as part of the Information Storage Industry Consortium (INSIC) program in Heat Assisted Magnetic Recording, with the support of the U. S. Department of Commerce, National Institute of Standards and Technology, Advanced Technology Program, Cooperative Agreement Number 70NANB1H3056.

Representing more than 42,000 members from all around the world, the APS promotes the advancement and diffusion of the knowledge of physics in the belief that an understanding of the nature of the physical universe will be of benefit to all humanity. The Society also publishes the world's most prestigious and widely read physics research journals.

About HAMR Technology
HAMR technology will significantly extend the capacity of modern magnetic disc drives that use magnetic heads to read and write digital data onto spinning platters. HAMR achieves higher densities by using a laser-beam or other energy source to heat the recording medium at the same time that data bits are being recorded. HAMR technology will also achieve its high areal densities at a cost structure on pace with the hard disc drives of today, making it a key enabling storage technology that will allow the adoption of mass storage to continue to enter emerging markets.

Seagate's Research division has worked on HAMR technology in addition to other promising storage technologies since its research center was first founded in 1998. Seagate estimates that HAMR technology will be used in disc drive devices initially at 1 terabit per square inch densities, with a time to market of approximately 2010.

"The pursuit of key technologies such as HAMR is part of Seagate's long-term strategy to maintain its position as the leader in storage to ultimately satisfy the needs of our customers today and tomorrow," said Bill Watkins, Seagate president and chief operating officer. "Seagate's research team is our looking glass into the future that will continue to help guide us with selecting and developing the appropriate future technologies that will lead to best-in-class, quality products for our customers."
