I read about holographic storage about the time the compact disc came out.
I don't know what the reader looks like now, but then the non-moving piece
of photo negative (reproduced by contact printing, real cheap) was "played" by
a laser which tracked across using a moving mirror to direct it.
The idea was read-only, however, no recording. Still, the technology
isn't all that new.
