I do have a video hard disk in my collection. This is a
head-per-track
hard disk rotating at 3000 rpm, such that 1 frame of TV video can be
recorded on each track. It uses FM (analogue) modulation to do this.
I saw a demo of this on an ordinary hard drive's mechanicals
in the late 80s. A friend recorded and played-back perhaps
ten or fifteen seconds of video on a (I think) 40 meg drive.
It was purely analog, not digital. (Amigas were early users
of IDE drives, so it might've been IDE, although that doesn't
really matter in this case, does it?) It was very futuristic at
the time, considering that comparable pro systems cost more
than a house. He soon developed the Amiga's Video Toaster and
even later, the Flyer, a hard-disk-based recording and editing
system.
