Yes,that is betacam SX,still in use at CBS NY and
other networks for news gathering.
We are now switching over to a new format
by Sony called XDCAM.It records the video data
to a rewritable disc that is about the same size as
a DVD.The disc usually lives in a cartridge and looks
a little bit like the old JAZ drive cartridge.The laser
in use is the new blue-violet laser.So far it works
very well but the technology is still very new.
