Holoplex is a startup company doing holographic memories. Info on the
web at http://www.holoplex.com/holoplex/. They reportedly have a
100-image store available as a product. (rdv, 96/7/23)

Tamarack Storage Devices, Inc, a spin-off from Microelectronics and 
Computer Technology Corporation (MCC), is developing with Projectavision Inc. 
to produce a product with ten times greater storage densities than magnetic 
and 10 to 1000 times faster than floppies, tapes, and CD-ROMS.  First 
products expected first quarter 1994.

Note: obviously Tamarack hasn't changed the storage world yet; anybody
know how they're doing? They were awarded another $10.7M by ARPA in
1995 for continued research, but I can't even find a web page for
them. (rdv, 96/7/23)

Also another report of experiments at Stanford recently (8/94).

Scientific American in the Nov. 95 issue reportedly has an article
about holographic storage, but I haven't tracked it down yet.

BYTE Magazine - April 1996
Good Cover Story on "Holographic Storage"

The trade journal "Data Storage" for May/June 1996 had an article
on holographic storage.

Reportedly there is work going on at Georgia Tech on 3-D liquid
crystal data storage, producing a possible gain of 3 orders of
magnitude. (rdv, 1996/3/29, from HPCWIRE)
