Abstract	The high density recording characteristics of barium ferrite thin film media have been investigated. High levels of overwrite are achieved. Media microstructures have been identified to have a close relation to the noise behavior in the barium ferrite thin films. A linear increase in noise spectra is observed, indicating the existence of transition noise. In addition, positive /spl Delta/M peaks are seen in all longitudinal barium ferrite samples. Magnetostatic interactions rather than exchange interactions among neighboring grains are believed to be the cause of the positive /spl Delta/M. To reduce media noise, a reduction in both grain size and grain aspect ratio is necessary.
