A disk drive having reduced electromagnetic emission quasi-peaks is provided. The repetition rate of servo blocks or data is reduced, spread or otherwise altered. In one embodiment, the number of data zones is increased to achieve an emissions reduction goal. In one embodiment, the disk drive is configured to effectively have one track per zone. In one embodiment, the rotation rate of the disk is varied or the effective data bit density, as detected by the read/write head, is otherwise varied. In one embodiment, servo-sectors are intentionally positioned to vary the length, along the track, of inter-servo intervals.
