Abstract
High-density recording requires longitudinal magnetic recording media with high coercivity and low noise. We report our studies of magnetic and microstructural properties of high-coersivity CoCrTa films. A coercivity of 2450 Oe has been obtained by applying a high bias voltage to the substrate. Microstructural analysis by TEM and electron diffraction studies revealed that in high-coercivity film c-axes are strongly oriented in the film plane.
