Abstract
A system, method, and device for sensing temperature during the writing of information onto magnetic media and providing a sufficient write current for that temperature is disclosed. The system comprises a head responsive to a write current for generating a magnetic flux used in writing data onto the magnetic media, a write current source coupled to the head for receiving a write signal and providing write current to the head, and a temperature responsive device coupled to the write current source that senses temperature and provides a write signal whose magnitude is dependent on temperature.
