Discusses the history of mechanical devices to store sound information from Thomas Edison's tin foil phonograph to the compact discs (CD) and beyond. (JOW)

Provides an update on optical disk technology as a means of digital media storage and explains why it may become a standard storage technology for telemedia technology. Topics discussed include read-only formats; write-once formats, including WORM and CD-WORM; rewritable formats; videodiscs; and future possibilities. (LRW)

Discussion of digitizing an archive's photograph collection focuses on the FEAR method (Funding, Equipment/Expertise, Approach, and Rationale). Topics include whether digitization is an appropriate choice; formulating objectives; file format and compression; storage alternatives, including CD-ROM; and outsourcing. (LRW)

Describes the latest technology in videotape cassette systems and other magnetic storage devices and their possible effects on optical data disks. Highlights include Honeywell's Very Large Data Store (VLDS); Exabyte's tape cartridge storage system; standards for tape drives; and Masstor System's videotape cartridge system. (LRW)

Describes the advantages of optical data disk-based storage systems including cost, performance, and space required. Conversion from tape-based to optical disk-based data management via a flexible, hardware-based optical archiving system is discussed. (Author/LRW)

Discusses library archival information as an essential element in librarians ability to establish themselves as competitive providers of information; describes problems with conventional archive storage methods; recommends recordable CD-ROMs for an electronic archiving media; and gives an example of document management software used with…

Explores the new storage technology of optical data disks and introduces a data structure, the inverted signature tree, for storing data on optical data disks for efficient text searching. The inverted signature tree approach is compared to the use of text signatures and the B+ tree. (22 references) (Author/CLB)

Describes CD-Recordable (Compact Disk-Recordable) as an economical information storage medium. Business and government applications are discussed, including prototyping, archiving and back-up, sales, marketing, accounting, and customer support and service. Future possibilities are also considered. (LRW)

Discusses electronic books and hypermedia as stages in the evolution of media used for the storage and transmission of information. Design features of a hyperbook being developed are described, and a future optical storage device called a BOOK (Binary Operating system for the Organization of Knowledge) is explained. (seven references) (LRW)

Discusses digital imaging technology and examines document database conversion considerations. Two types of document imaging systems are described: (1) a work in process system, and (2) a storage and retrieval system. Conversion methodology is outlined, and a document conversion scenario is presented as a practical guide to conversion. (LRW)

Compares two approaches to document delivery and storage--microform and CD-ROM--in terms of storage capacity, accessibility, production, and cost considerations. Strengths and weaknesses of each medium are noted. It is concluded that libraries should select, integrate, and explore the different features of both technologies. (12 references) (MES)

This special issue on CD-ROM comprises six articles covering the following topics: (1) an overview of the library market; (2) the producer's perspective; (3) implementation issues; (4) problems; (5) future needs and trends; and (6) a 23-item bibliography which includes an annotated section designed as a self-instructional module. (MES)

The integration of optical disk systems employing WORM (Write Once Read Many) technology with CD-ROM systems can enhance information management. Two integrated system applications are the Paperless Ship Project of the U.S. Navy and the FEDLOG (Federal Logistics Data on CD-ROM) of the Defense Logistics Agency. These initiatives are described and…

Discusses the Scottish Newspapers Microfilming Unit's interest in conversion of microfilm to digital technology. Concerns include cost, potential market, reliability of digital technology as a preservation medium, and the necessity to have both microfilm and digital formats for preservation. Solicits feedback and information from colleagues on the…

This digest begins with a brief description and review of the development of optical disks. Optical disk formats are then described by capability: Read Only Memory (ROM), Write Once, Read Many (WORM), Interactive (I), and Erasable (E); forms of information (audio, text or data, video or graphics, or a combination); and disk size (most often 12 or…
