Two large Defense Department projects managed by Lockheed Martin Corp. and
McDonnell-Douglas Corp. are beta testing the CRI-X software, CD ROM-USA Inc. president
Roger Hutchison said.
One by-product of the Golden, Colo., company's compression process is an extremely high
level of data encryption. Another by-product is "a proportional benefit, so that the
more compression you get, the faster the retrieval is," Hutchison said.
The CRI-X optical disk compression process simulates the file allocation tables of
magnetic hard drives. Files compressed and recorded on CD-ROM without the licensed CRI-X
code will end up as "a bunch of binary information with no way to decode it,"
Hutchison said. "The operating system doesn't know where each file starts and
The federal government is potentially a big customer for CRI-X, because most federal
data stored on optical disk is binary information such as satellite imagery.
The CRI-X compression ratio for binary data runs as high as 16:1, which translates into
as much as 100G of storage on a single DVD-ROM disk, Hutchison said.
Besides CRI-X software, CD ROM-USA resells CD-ROM drives and the new high-capacity
DVD-ROM and DVD-recordable drives on its General Services Administration schedule
The compression process is fully compatible with International Standards Organization
specifications for CD-ROM, Hutchison said. Licenses for CRI-X compression will add about
10 cents to the cost of each CD-ROM and 50 cents to the cost of each DVD, he added.
