True, as far as I know.  Some drives use RLL3,9 (to get some more
capacity) and slower rotation speeds.  For example, the Seagate 296N (80
MB, half height) and 251-1 (MFM 40 MB) have the same number of heads and
cylinders.

Dennis had stepped up into the top seat whet its founder had died of a
lethal overdose of brick wall, taken while under the influence of a
Ferrari and a bottle of tequila. (Douglas Adams; the long dark teatime...)
