The effect of thermal energy (kBT), which has been found to play some important roles in the magnetic properties of recently developed antiferromagnetically coupled media, is described. It was observed that the thermal energy helps to obtain an antip

The origin of orientation ratio (OR) in longitudinal recording media has been controversial in the literature. In the past, the observation of a higher OR for thinner magnetic films has been attributed to stress or thermal effects. Our measurements,

To overcome the high sensitivity of the signal-to-noise ratio (SNR) to the switching field distribution in the perpendicular media, we proposed to use tilted media in the perpendicular recording system in this letter. It was found that a much better

There has been some disagreement in observation of the effect of oriented media on the recording performance from earlier and recent studies. In this letter, we have identified the reasons behind these disagreements by studying the effect of the ener
