<p>PROBLEM TO BE SOLVED: To provide an exchange coupling enhanced cap manufactured with argon and oxygen implantation.SOLUTION: This invention provides magnetic media having a novel cap layer that enables the cap layer having improved exchange coupling and reduced thickness. The cap layer is doped with a non-reactive element such as Ar, Kr, Xe, Ne or He, preferably Ar. This doping enhances exchange coupling and reduces dead layers, allowing the cap layer to be made thinner for reduced magnetic spacing and improved data recording performance.</p> |
