Abstract
Disclosed is a method for producing vertical recording media by using magnetically-assisted sputtering apparatus to sputter from a magnetic target while selected portions of the target are heated to a temperature at or above Curie. Also disclosed are improved means for supporting the magnetic target during sputtering which permits the realization of enhanced sputtering efficiencies.
