How does that work with a fixed head disk, one head
per track? So 64
heads in this case?
Yes, there's another version that has 128 heads.
Mine's the small one
which is only 64 heads.
0.58 MB capacity, what vintage is that?
Date stamp on the controller and the HDA is
1975.
How big is the platter(s)?
I'd guess
12-14".
What would be filled with helium? The volume in which
the platter(s)
rotate? Why helium?
The HDA is filled with helium. Helium being lower density
than normal
air, allows the heads (and the coaxial motor) to run cooler (less "air"
resistance).
Is it interesting enough to look at to take pictures and post them?
Once I get it all mounted, sure.
