Wideband Holographic Digital Recording and Reproduction
Abstract
Techniques were investigated to apply the concept of holography to the problems of wideband digital recording and reproduction. The feasibility of recording at rates up to 2 Gb/s and playback at both full-record and reduced speeds was theoretically and experimentally considered. The program was a multi- phased effort including the design, development and experimental evaluation of two Exploratory Development Models (EDMs): the Phase I EDM demonstrated recording at 400 Mb/s and playback at 40 Mb/s, and was used to guide design trade-offs for Phase II; the Phase II EDM demonstrated recording at 600 Mb/s playback at full-record and 0 to 1 time expanded rates with bit-error-rates better than 1/1,000,000. Both full-system operational testing and parametric evaluation on a component basis were performed. This report describes design and performance data at both the system and the subsystem levels for the Phase II hardware. Also a part of this program was the development of conceptual designs for portential multi-gigabit recorders. These designs are presented, along with system and subsystem level trade-offs between the various concepts, and recommendations for subsequent development.
