Abstract

The perpendicularly oriented crystal structure conditions of electroless plated film for high density perpendicular recording media were investigated mainly by (002) plane rocking curves and cross sectional SEM observation. A highly oriented narrow dispersion of c-axis orientation normal to the surface plane was consequently obtained, and the columnar structure of hcp crystal with ca. 0. 05 mu m diam was confirmed. As a result of preparing disks A and B, which were chemically plated from an optimum bath and a more improved bath, respectively, the recording characteristics with a combination of ring head were obtained as recording densities of D//5//0 equals 18,500 FRPI for disk A and 25,000 FRPI for disk B, in spite of a relatively thick magnetic medium. The di-pulse waveforms, which are characterized with perpendicular recording, observed at low bit recording density.
