The STO generates a high frequency magnetic field on a magnetic medium. The controller is configured to supply the STO with first bias current at a first bias current level, and further supply the STO with second bias current at a second bias current level. The controller is further configured to time the second bias current to coincide with an electrical current overshoot in the write coils."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"STO bias control for MAMR head reliability","description":"The MAMR head comprises a main pole, a spin torque oscillator (STO) positioned over the main pole, and write coils coupled to the main pole.
