I recall the age old DD/HD debate with the
floppies - is there really
just one production line, and disks that are 'good enough' get
stampted with HD in the top right corner, and the rest are just deemed
DD and put in to other boxes.
Yeah, right.
(-: And on Kodak's only assembly line, they take small samples from each
roll of film; the ones that turn out to be fastest get marked TRI-X, and
the slower ones get marked PLUS-X. :-)
DD 5.25" disks are about 300 Oerstedt.
HD 5.25" disks are about 600 Oerstedt. DD 3.5" disks are about 600 Oerstedt.
HD 3.5" disks are about 750 Oerstedt.
Yes, there IS a chemical difference that creates the different coercivity.
