Patent ID: 8760779

Claim:
A system, comprising: a magnetic medium; a magnetic head comprising: a write element configured to record data on the magnetic medium; a microwave-assisted magnetic recording (MAMR) element configured to assist recording on the magnetic medium, the MAMR element comprising a microwave-generating portion that is configured to generate a localized AC field on a portion of the magnetic medium prior to and/or while writing data to the portion of the magnetic medium using the write element, the microwave-generating portion being configured to receive current for operation thereof; and a read element configured to read data from the magnetic medium; a first device configured to measure environmental conditions relating to the MAMR element and the magnetic medium, the environmental conditions comprising at least: temperature, a reproduced signal of the read element, and a clearance between the MAMR element and the magnetic medium; and a controller configured to: control operation of the magnetic head and adjust operating parameters of the system based on the environmental conditions provided by the first device, the operating parameters comprising at least: a clearance between the MAMR element and the magnetic medium, a write current, and an amount of current injected to the MAMR element; and increase an amount of current provided to the MAMR element at lower operating temperatures as compared to an amount of current provided to the MAMR element at higher operating temperatures.
