The driver is configured to output a signal to a preamplifier of a heat source based on a thermal compensation value to cause the heat source to heat a spot on a storage medium. The controller is configured to adjust the thermal compensation value based on a duration for which the heat source is in an active or inactive operational state. The thermal compensation value is indicative of a history of durations that the heat source was in the active or inactive operational state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thermal compensation for heat assisted magnetic recording","description":"A system includes a driver and a controller.
