Abstract

Time decay of magnetic properties in perpendicular magnetic recordingmedia was studied. It was suggested that magnetization in media with a low energy ratio, KV/kT, of 50 is thermally stable in the absence ofa demagnetizing field while coercivity exhibits a large time dependence. Magnetization in perpendicular recording media exhibited an appreciable time decay even for films with a large energy ratio of 300. The decay is attributed to the small perpendicular squareness due to a large perpendicular demagnetizing field acting in the media. The recording density dependence of the time decay in the output was explained in terms of the change in the demagnetizing field with the density. it isconcluded;hat the use of media with large squareness as well as largeenergy ratio effectively reduces rime decay in the output.
