Title: Achievements in optical data storage and retrieval
Abstract: The present paper deals with the current achievements in two technology efforts, one of which is a wideband holographic recorder which uses multichannel recording of data in the form of holograms on roll film for storage and retrieval of large unit records at hundreds of megabit per second. The second effort involves a system (termed DIGIMEN) which uses binary spot recording on photographic film in the form of microfiche to provide a mass storage capability with automatic computer-controlled random access to stored records. Some potential design improvements are noted.
