Massive Data Storage Utilizing STN Technology: Storage Medium
Abstract
Digital mass storage devices built on scanning tunnel in microscope technology can result in storage densities of 10 to the 12th power bits/cm2. In the STM based mass storage device electrons emitted from a microtip cause a physical change in a storage medium's surface. Current densities between the microtip and storage medium can be as high as 10(exp 6) amps/cm2 and electric fields can be as large as 10(exp 6) V/cm. It is anticipated that this new type of mass storage subsystem will have megahertz transfer rates and access times of several milliseconds per gigabyte. The objective of this SBIR Phase 1 contract is to evaluate potential storage media for read/write mass storage device utilizing STM technology. Several gas/solid, liquid/solid and solid system were evaluated for the storage medium. Storage media that show exceptional promise are magnetic materials, quantum structures, and electrochemical solutions. We conclude from this SBIR phase 1 research effort that it is possible to develop a read/write mass storage device from STM technology. There are several storage media that can be utilized; however, experiments must be performed to select the optimal storage medium. The level of effort required to successfully complete this research project is estimated at 10 man years. Because the SBIR program provides funding for projects requiring 4 - 5 man years, QuanScan will pursue funding for this research project from sources outside the SBIR program.
