Computer Engineering Eminent Scholar Seminar: 3D TB OPTICAL STORAGE INFORMATTION DEVICES

February 27, 2015 @ 4:15 pm - 5:25 pm

Room 1034 ETB

Peter M. Rentzepis

The first means for information storage and dissemination was 2D optical. Lately 2D magnetic disk storage became ubiquitous followed by 2D optical disks where Mbytes and GBytes are stored and retrieved.

In this talk we will discuss the spectroscopic processes and engineering techniques for writing and reading TBs of information in 3D disks and other devices. The basis for 3D writing, within the volume of a disk, or cube, rests on two photon, virtual, absorption. This method allows for recording information explicitly at a pre-determined small spot within the volume of the “disk” without affecting any other part of the device. The materials used and their properties for writing and reading 3D information will be discussed. The optical system and platform necessary for achieving high storage and retrieval rates will also be presented and the system used to store more than 10 TBs in a disk will presented and its limitations, such as BER, fatigue and other properties will be presented. Future possibilities to increase the storage to petabytes will be discussed if time permits.
