Not just that, but the aerodynamics have been screwed up. The heads will
no longer "float" on an air-cushion; I believe the gap is the traditional
human hair width, if that.
Trivia: there is a small NiCd battery in the RK-05 drive which has to be
replaced every so often; its sole job is to drag those heads back in the
event of a power failure, whether it was writing at the time or not.
