When my friend brought the comp home, the drive was running as
1.2MB. As the previous owner had used it for accounting, I think it is
concievable that they upgraded it.
RE density-- IIRC, we were told in High School (that's going back a
while :-) that the signals are recorded in the magnetic medium as
ramps. "Double density" meant that the signal ramped, at the same rate,
for 1/2 the time. As this produced an overall signal with 1/2 the
amplitude, more sensitive transducers and amplifiers were needed for
reliable data transfer.
I had never heard about different track widths before. Are narrower
tracks only used on 1.2MB drives?
