Abstract: Dynamic fly height (DFH) control is obtained for a read/write head by use of a heating element having two laterally separated heat sources symmetrically spaced around the track center line of the head. The two heating sources create a protrusion profile relative to the undistorted ABS that recesses the read element and main write pole at the track center line relative to off-track positions. The resulting DFH control also protects the head from HDI (head-disk interference) events that are either the result of calibration procedures or normal HDD (hard disk drive) operation.
