Abstract
Information storage products are undergoing constant change. Computer hard disks have shrunk in
size, from two feet in diameter in the mid-1950s to a few inches or less today, while holding
ever-larger amounts of data. Data tape reels have been replaced by compact cartridges of half-inch
tape. Thirty years ago, eight-track tapes gave way to audio cassette tapes, and compact discs are
edging out cassette tapes and floppy disks. Higher capacity digital versatile discs have since
emerged, while hard disk and recording head technology continues to evolve, making hard disk drives
a somewhat unique mainstay. Newer technologies continue to be developed to take storage capacity and
speed to the next level. Megabytes have given way to gigabytes. Terabytes are not far behind.
These changes in storage technology and capacity have mandated changes in media materials. Materials
critical for one type of storage product may be unsuitable for the next generation. Particles, thin
film structures, and even substrates have changed as magnetic and optical storage products evolve
with new generations of products. Smaller, thinner, more complex and more precise could well be the
mantra of producers of information storage media and devices.
This report covers the gamut of current and emerging magnetic and optical storage media, including
magnetic recording tapes, hard disk media and recording heads, optical disks and emerging storage
technologies, including new optical disk formats, holographic recording, near-field recording, as
well as the materials required to produce these media and devices.
