<title>Holographic Storage</title>

Abstract

Storage of data using holographic techniques continues to hold the interest of researchers here and abroad even though the development of practical computer oriented holographic systems has been progressing at a slow rate. Several read/write demonstration systems have been built recently but further significant progress awaits the development of advanced page composers and materials or a more novel way of using presently available technology. The application of holographic techniques to data recording on photographic film has been more successful since the materials technology, as well as the page composer technology, are well in hand. This paper reviews the recent progress in holographic data storage and discusses a number of ways of utilizing holographic techniques in recording data.
