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)

Discusses the wide variety of installation standards currently maintained by publishers of CD-ROM databases and the problems this can cause for users. Hardware and software requirements of various CD-ROM databases intended for use on IBM personal computers and compatibles are described. (five references) (CLB)

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)

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 compression methods for components of full-text systems such as text databases on CD-ROM. Topics discussed include storage media; structures for full-text retrieval, including indexes, inverted files, and bitmaps; compression tools; memory requirements during retrieval; and ranking and information retrieval. (Contains 53 references.)…

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)

Reviews several CD-ROM products displayed at the March 1989 International Conference on CD-ROM sponsored by Microsoft. Product capabilities for handling text, audio, images, and full motion video are described, and potential applications for information retrieval are discussed. (CLB)

Provides an introduction to the technical aspects of digital audiotape and compares it to other computer storage devices such as optical data disks and magnetic tape cartridges in terms of capacity, transfer rate, and cost. The current development of digital audiotape standards is also discussed. (five references) (CLB)

Examines Photo CD as a possible standard storage medium. Functionality within the system is explored, including future-proofing implications and application hints for practitioners; two case studies illustrate typical applications, one at the University of Aberdeen (Scotland) and one at a commercial image archive laboratory. (Author/LRW)

Discussion of CD-ROM and DVD (Digital Video Disk)-ROM covers CD-ROM software pricing and industry changes; CD-ROM drives; CD-recordable formats; DVD formats, hardware, and software; recordable DVD; and future issues, including standards, Windows 98, the DVD market, and compatibility.
