Title

DVD-ROM : CD-ROM on steroids

Source

Information today. 14(1997) no.9, S.30,34

Year

1997

Abstract

Discusses the merits of DVD-ROM as a medium for the storage of large quantities of text, numeric, and multimedia data. Focuses on the performance of DVD-ROM, including transfer rates, access time, and storage capacity. DVD-ROM provides a 4,7 GB storage capacity with transfer rates equivalent to a CD-ROM's 20x or 24x, or 3 MB/sec to 3,6 MB/sec, and access times of between 150 and 220 ms. DVD-ROM could become a viable alternative to CD-ROM if the MPEG-2 and Dolby AC3 decoder became options, significantly reducing the cost of the base drive for those whose information storage needs do not require them. Compares image quality, product, and price of CD-ROM and DVD-ROM. DVD-ROM would be a good solution for publishers of multi-volume CD-ROM titles
