| 发明名称 | Cooling periods used during the writing of bit boundaries to a magnetic recording media | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method comprising: determining polarity transitions of a write signal applied to a write coil, the polarity transitions corresponding to first bit boundaries written to a magnetic recording media; and applying a heat signal to heat the magnetic recording media via a heat source while bits are being written, the heat signal comprising negative pulses that de-energize the heat source during cooling periods corresponding to the writing of the first bit boundaries, the negative pulses offset from the polarity transitions by a predetermined time. | ||
