Write commands through a read/write head are regulated in response to head fly height. The head fly height is determined, and the rate at which the write command is carried out is regulated in response to the determined fly height. The rate may be regulated by inserting write inhibit gaps between writing data segments of the write command so as to allow the head to cool and, thereby, control fly height.
