Abstract
Polarity transitions of a write signal applied to a write coil correspond to first bit boundaries written to a magnetic recording media. A heat signal is applied to heat the magnetic recording media via a heat source while bits are being written. The heat signal includes negative pulses that de-energize the heat source during cooling periods corresponding to the writing of the first bit boundaries. The negative pulses are offset from the polarity transitions by a predetermined time.
