An epoxy glue sold at hardware stores and a glass-like substance were formed into a DVD-size disk able to hold about 87 gigabytes, equal to 87,000 paperback books. A typical DVD holds about 4.7 gigabytes. The discovery is unique because the materials remained stable, keeping data intact, the project's leader said.
Companies including International Business Machines Corp. are exploring ways to increase computer data-storage capacity, while reducing costs and size in devices ranging from desktop personal computers to massive machines able to hold the contents of the U.S. Library of Congress. Optical storage holds less data than a magnetic hard-disk drive yet is more stable and rugged
