Not quite. There *IS* a difference in media between IBM 1.2 meg
disks and IBM 360K disks / Quad density 720K disks. If you don't
believe me, try taking a 360K disk, and formatting it to 1.2 megs.
OTOH, as has been noted you can format 360K disks to 720K (or even
800K) in an IBM 1.2 meg drive: I have a couple of utilities to do
this, and use the 800K format for all my archival backups. It
provides by far and away the best cost per megabyte: 25 cents for
800K works out to about 32 cents per megabyte.
