Thin film magnetic alloy having low noise, high coercivity, and high squareness

A magnetic recording media for horizontal recording, comprising:

• a substrate;
• a nucleation layer sputter deposited on said substrate;
• and
• a sputter deposited magnetic layer, which exhibits ferromagnetism as deposited and which is not heat treated after deposition, formed over said substrate, the magnetic layer having a composition comprising an alloy of cobalt and platinum, said magnetic layer doped with nitrogen in an amount greater than approximately 1 atomic percent, the sputtered magnetic layer doped with nitrogen exhibiting a higher signal-to-noise ratio than the sputtered magnetic layer without nitrogen.

A magnetic recording media for horizontal recording, comprising:

• a substrate;
• a nucleation layer sputter deposited on said substrate;
• and
• a sputter deposited magnetic layer, which exhibits ferromagnetism as deposited, formed over said substrate, the magnetic layer having a composition comprising cobalt, platinum, and nickel, said magnetic layer further being doped with at least one element selected from the group comprising B, P, S, C, Si, As, Se and Te;
• the magnetic recording media having an as-deposited coercivity of at least 1400 Oe.
