Abstract
To achieve both the high anisotropy energy and high SNR performance at ultra high areal recording density, we have studied paired recording layered PMR media named as hybrid media. Hybrid media consist of 1/sup st/ recording layer and 2/sup nd/ recording layer. 1/sup st/ recording layer and 2/sup nd/ recording layer have low noise properties and high anisotropy energy, respectively. 1/sup st/ and 2/sup nd/ recording layer are continuously and coherently stacked on the top of the underlayer.
