More Information
Summary:The present embodiments relate to a thermally-assisted magnetic recording (TAMR) head. A magnetic assist current can be applied to the TAMR head to assist in reducing timing jitter as the TAMR head interacts with a magnetic recording material. The TAMR head can include a main write pole including a tip portion and configured to direct a magnetic field for interacting with a magnetic recording medium. The TAMR head can include a laser diode to heat the magnetic recording medium and a dynamic fly height (DFH) heating element for dynamically controlling a height of the main write pole. The heating element can be of a parallel bias circuit that directs a direct current (DC) bias current flow along an electrical path from the magnetic yoke element to the tip portion of the main write pole adjacent to an air bearing surface (ABS).
