Subject: CD-ROM Longevity (acc. to 3M)

I reproduce below the leading paragraphs of a story just published in
"Imaging World", April, 1992 ( a free flak paper for the industry, monthly):

CD-ROMs pass 3M stress tests
by Mark Fritz

While CD-ROM as a technology for storing images may not last through the
next century, the disks themselves surely will.  That was the message of
assurance 3M had for the attendees of the recent International Conference
and Exposition on Multimedia and CD-ROM.

In an attempt to quell industry fears that compact disks are deteriorating
faster than expected, 3M has put its disks thropugh rigorous environmental
stress testing like the kind auto manufacturers often use to test th elife
expectancies of tires and other automotive parts.  The company announced its
test results at the Microsoft-sponsored conference in San Francisco,
March 9-11.

According to 3M, the life [cont. on p. 26] expectancy of a CD-ROM disk under
normal circumstances is 100 years or more.  And to show its confidence at
the conference in this claim, 3M also announced at the conference that it will
warranty its disks for 25 years.

Other CD-ROM related news at the conference included announcements by both
Pioneer and Sony that the are now offering double-speed drives....[etc. etc.]

[article started on p. 1].

I offer this fyi with no comment.
