Optical Discs Versus Magnetic Storage

This book provides a comparison of optical and magnetic devices as computer storage technologies. There are three sections, with each section discussing the similarities and differences in recording technology, storage capacity, performance characteristics and cost. Major points raised in the text are summarized in a series of graphs that compare specific optical and magnetic storage configurations. It also contains cost analyses that are based on equipment and media prices prevailing in early 1990. While specific costs will change in the future, the cost comparisons presented should retain their significance, enabling users to recalculate the cost comparisons to reflect changing prices. The book should be of particular interst to computer specialists, information systems analysts, administrative managers and other responsible for computer system planning and selection, including those wishing to install document image processing. This report should help such readers clarify their thinking about the competitive and complementary relationship of magnetic and optical storage technologies.
