The method involves measuring a metric of write performance subsequent to the write operation at each of the operating temperatures. The method also involves detecting one or more laser mode hops using the metrics, and determining a temperature at which each of the detected mode hops occurred. The method further involves storing the temperature for each detected mode hop in a non-volatile memory of the drive. The method may involve mitigating laser mode hopping, such as by the drive avoiding the stored temperature(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser mode hopping detection in a heat-assisted magnetic recording drive","description":"A method comprises performing a write operation using a heat-assisted magnetic recording (HAMR) drive operating at a plurality of temperatures.
