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)

Fourth installment of a directory published in four parts in "Database" (June and August) and "Online" (July and September) provides descriptions of 12 laserdisk products together with information on the producer, compatibility, type of laserdisk, search and retrieval software, interface with magnetic media, conditions of usage, price, and status.…

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two. (MBR)

Reviews terminology inherent in discussing microcomputer storage technologies and addresses aspects of magnetic storage and present and near-future technologies, including floppy disks, Winchester and removable hard disks, optical digital disks, optical video disks, (audio) compact disks, perpendicular magnetic recording, and erasable optical…

Holography is one of the most promising methods now under research for the achievement of high bulk storage with fast random access at a reasonable cost. (Author)

Physicians wishing to become computer literate face two immediate problems. First, there is no readily available nor universally accepted statement of what such literacy should entail, and second, such pedagogic mechanisms as exist are not widely available. This paper addresses both problems. (SSH)

A wide range of computer crimes and the need for computer security are discussed. (MK)

One of today's major problems in the field of e-learning is that the creation of high-quality content is still rather time consuming and expensive. In the past, many efforts have been made to produce educational content on the fly, but the results were mainly static blocks of recorded lecture lacking sophisticated navigation facilities. Facing…

Large central databases which support multicampus users require thorough planning and coordination, special communication with both users and input sources, and organized retrieval systems. In the developmental process of identifying variables that should be in the system and designating the source of that data, old habits of multiple official…

An interactive search and editing system, 3RIP, is being developed at the library of the Royal Institute of Technology in Stockholm for large files of textual and numeric data. A substantial part (on the order of 10-E9 characters) of the primary file of the search system will consist of bibliographic references from a wide range of sources. If the…

Interactive computers are providing more services to greater numbers of users. However, before such systems can be economically applied to public education, the cost of high performance memory must be reduced. By using massive amounts of serial memory in conjunction with a highly sophisticated memory controller, a system was constructed which…

The Inverted File Information Retrieval System (INFIRS), is a document search system which offers a comprehensive range of search facilities. It has been developed at the United Kingdom Chemical Information Service (UKCIS) as a general purpose retrieval tool, suitable for handling a wide variety of data-bases (both free-text and controlled…

This study sought to design an effective management information system for an Illinois community college. It was developed by (1) displaying all the college activities as a system with six functionally independent subsystems, (2) reducing subsystem data to basic elements, (3) analyzing administrator response to choice of data items, (4)…

Introduction to use of compact disk technology for storing digital data highlights history, background, and developments; technical features; standardization issues; current CD ROM applications; and the market for CD products. A production diagram, a sampling of CD manufacturers and disk replicators, and performance comparison of three storage…

Review of similarities and differences between magnetic-based and optical disk drives includes a discussion of the electronics necessary for their operation; describes benefits, possible applications, and future trends in development of laser-based drives; and lists manufacturers of laser optical disk drives.
