This is correct. For 5.25" disks, one can have 8 or 9 sectors per
track and one or two sides of 40 tracks under DOS with double-density
diskettes; with high-density ones, you get 15 sectors per track, 80
tracks per side, two sides. The various capacities you can get are
then 160K, 180K, 320K, 360K, and 1.2M.
