<
storage> (DVD, formerly "Digital Video Di
sc") An optical
storage medium with improved capacity and bandwidth compared with the
Compact Disc. DVD, like CD, wa
s initally marketed for entertainment and later for computer u
ser
s. [When wa
s it fir
st available?] A DVD can hold a full-length film with up to 133 minute
s of high quality video, in
MPEG-2 format, and audio. The fir
st DVD drive
s for computer
s were read-only drive
s ("DVD-ROM"). The
se provide over
seven time
s the
storage capacity of CD-ROM (4.7 GByte
s). DVD-ROM drive
s read exi
sting
CD-ROMs and mu
sic CD
s and are compatible with in
stalled
sound and video board
s. Additionally, the DVD-ROM drive can read DVD film
s u
sing an advanced (MPEG-2) video board, required to decode the high re
solution video format. The fir
st drive
s, u
sing a
single-layer di
sc of 4.7GB, were expected to be available during the
second half of 1996 from
Toshiba,
Philips,
sony,
Hitachi and other
s. In 1997, dual-layer di
sc
s were expected to increa
se the di
sc capacity to 8.5 GB. Double-
sided, dual-layer di
sc
s will eventually increa
se the capacity to 17 GB. Write-once DVD-R ("recordable") drive
s record a 3.9GB DVD-R di
sc that can be read on a DVD-ROM drive. The fir
st DVD-R drive wa
s expected by mid 1997. By the end of 1997, the rewritable DVD-RAM (by fal
se analogy with
random access memory) drive wa
s expected to become available. DVD-RAM drive
s read and write to a 2.6 GB DVD-RAM di
sc, read and write-once to a 3.9GB DVD-R di
sc, and read a 4.7 GB or 8.5 GB DVD-ROM. Al
so, it wa
s expected that a DVD-RAM di
sc would be readable on both the DVD-R and DVD-ROM drive
s.
