1. A method of sensing and controlling a temperature of a resistive element configured for use in a read/write head of a magnetic data disk storage device, the method comprising:

  • detecting a voltage across the resistive element of said magnetic data disk storage device, the voltage varying as a function of a temperature of the resistive element;

    comparing the voltage to a predetermined value to determine a variation of the voltage from the predetermined value; and

    altering a power applied to the resistive element based on the variation, the temperature of the resistive element varying as a function of the altered applied power.
