A vertically stacked DFH design in a read/write head is disclosed that allows independent control of write gap protrusion and read gap protrusion. A first heater is formed in an insulation layer proximate to a sensor in a read head. A second heater is formed in a second insulation layer proximate to the write pole tip in a main pole layer. The two heaters are connected in series or in parallel through leads to a power source that activates the heaters. In one embodiment, the heaters have a fixed resistance ratio. Preferably, there are two drivers in the power source so that a first power can be applied to the first heater and a second power can be applied to the second heater to enable an adjustment of reader protrusion/writer protrusion or gamma ratio. Fast reader and writer actuation is achieved and low power consumption is realized.
