Let's be clear here--I interpret 5.25 DD to be
360K
(250K data rate
at 300 RPM) at 48 tpi. And "quad" to me is the same
data rate but
narrower tracks for 96 tpi and 720K. AFAIK, the
only difference
between DSDD and DSQD was the supposed certification
provided by the
mnaufacturer. I never found any difference at all.
Well I wish you could have been clear about this ~20
years back. I thus wouldn't have blown all those extra
cordobas on senseless certification! Sheesh!
