Since the only system I ever used an 8" DSDD
floppy was the PDP-11
using a DSD 880/30 with the (emulated) RX03 drive, I don't have sufficient
knowledge of what any other manufacturers did.
But, at least the floppy drive in the DSD 880/30 definitely had two sensors
with two detection circuits, as mentioned by Tony.
We all know that DEC used a SS / DS drive.
The question is whether there existed anybody who mad DS without the SS
sensors.
The original question had been about an SA800 drive, and did not mention
DEC.
