Abstract

The exchange coupling optimization on CoPtCrO perpendicular media was discussed. It was shown that at low oxygen gas ratios, the H_n and H_c show similar values and the Kerr loops are very square. At around 1% oxygen gas ratio, the loop slope became inclined and the coercivity increased to greater than 5000.
