| 英文摘要 | Embodiments described herein involve a method comprising generating a seek command in a heat-assisted magnetic recording (HAMR) device. A first current is supplied to a laser diode of the HAMR device in response to the seek command to preheat the laser diode. The first current is insufficient to cause erasure of data on media of the HAMR device. A second current that is greater than the first current is supplied to the laser diode for writing to a magnetic recording medium of the HAMR device after executing the seek command. Preheating the laser diode reduces a likelihood of a laser mode hop occurring while writing to the medium. |
