Adaptive HAMR Laser Power Data Storage Device |
摘要 |
A data storage device and associated methods may provide at least a data storage medium that is separated from a heat assisted magnetic recording data writer and is connected to a controller. The controller can be configured to change a laser power of the heat assisted magnetic recording data writer in response to a tested bit error rate of a median data track of a plurality of adjacent data tracks reaching an identified threshold. |

1. An apparatus comprising a data storage medium separated from a heat assisted magnetic recording (HAMR) data writer connected to a controller configured to change a laser power of the HAMR data writer in response to a tested bit error rate (BER) of a median data track reaching an identified threshold, the tested BER corresponding to writing a common test pattern to a first data track more than twice, the first data track being immediately adjacent to the median data track. |
