That is correct. Pappas Telecasting's new Reno studios support two stations
in a tape less environment, broadcasting the CW networks HDTV signal as well
as producing newscasts in HD for both the CW and the TV Azteca network
stations. The studio and operations are technically very advanced and are a
pleasure to behold.

Doug and John:
I don't know about 3 TB, but I do know that InPhase Technologies is
currently getting 300 GB on their holographic media, have 800 GB working
in the lab on the same media and have forecast 1.6 TB by 2010 on the
same media. It is worm (write once read many) right now, but they say by
2008 (less than 18 months) they will we have it rewritable. They were
showing the 300 GB at NAB this year in the Maxell booth. Tapestry 300-R
Enables 300 Gigabytes on a single disk at 20 Megabytes per Second They
say their product will ship to their first customers by the end of this
year.
InPhase is already in the U.S. broadcast market. I know for sure that
Pappas Telecasting will have a unit at their Reno station and will be
among the first to integrate holographic drives into their broadcast
work flow. Turner Broadcasting, in October, 2005, was the first to
demonstrate play-out-to-air of a commercial from a holographic system,
using the prototype of the Tapestry 300-R.
The issue holding back on more onto the media is the spectral light
modulator that gets the information onto the media. The media itself is
capable of holding up to 17 TB, but getting it on there in the finer
resolution is the issue. The media does not rotate like a CD or DVD, it
moves only incrementally. Right now the media is in a CD form factor,
but that is not necessary. It can be in the shape of a credit card or
whatever. You can see all of this on their website -

I had a prototype unit with me on most of the Road Show this year and
hope to have a full working unit this next year. This is NOT vaporware –
really works.
