[QuadList] HS-100 disc

[David Crosthwait]

Very interesting note Dennis on the Reeves modifications. That's what engineers did when there was a task: Invent!

In so far as cooling, one of Don's literature links features HS 100 cooling:

Was that similar to the Reeves air filtration/cooling system?

The one we had at R/T was specially modified by the Reeves machine shop.  They made little aluminum mounting blocks with screw adjustments on them to beef up the stability of the flying head positioning.  Once aligned, the heads STAYED aligned for a long time.  Reeves also had modifications of the air filtration system to improve cooling.
