The heads use airflow and a venturi to maintain the air bearing and
are on the end of a springsteel finger designed to flex quite a distance.
 
Movement of the platter would have to be pretty extreme and sudden to 
cause the heads to touch - a typical example is the sudden deceleration
at the end of a drop.

Given the time and cost of lubing the bearings vs the likely short
reamining lifespan of the drives I'd agree.
