CD ROM drives continues to decrease—
the current price fluctuates between
$500 and $700—the number of installed
| drives in corporations is growing expo-
| nentially; today there are approximate-
| y 200,000 CD ROM drives installed, and
that number is projected to swell to ,
| 350,000 by 1992,
The number of CD ROM applications
| is also on the rise. For example, Lotus
Development Corp. offers Prompt CD,
a collection of technical-support notes,
| evaluation and demonstration versions
of selected software, 'press releaseš and
full text from Lotus Magazine. Com-
| puter Library: 'produčed 'monthly by
Zitt Davis Publishing Co., contains full
| text from its family of Computer publi-
pations, as well as full text and ab-
stracts from 120 other peribdicals."

, There has also been a'surge in'the
number « of successful in-house corpo-
rate CD ROM publishing ventures;
again heightening the credibility of the
| technology, Each month, a division of
| Ford Motor Co. publishes a CD ROM-

based inventory list of 300 ,000 parts
for its 2,400 dealers. Compag Comput-
er Corp. stocks its resellers with
OuickFind, a CD ROM tool used as a
| source for technical Support, product
research and technical kalning,

Preparing text for CD ROM publish-
ing involves many processes. An au: ..
thoring process gathers the'text collec-
tion arid prepares it for transfer to disk. |
The: text is then indexed, and a premas-
tering step converts the text and index |
files into a CD ROM format. An optical |
disk master is then created and repli-
cated for distribution. Mastering an op- |
tical disk costs around $1,500—which
usually ineludes the replication of about
100 disks. Incremental disks can run as
low as $2 each. H
