Title: Magnetic disk
Inventor: ISHII TOSHIO
IPC: G11B5/66
Filed: 1992-09-11
Abstract: PURPOSE:To improve a missing error characteristic and to decrease the variations in quality by using a substrate which consists of titanium or titanium alloy and has <=0.03mum Rmax surface roughness of the surface. CONSTITUTION:The Ti substrate is subjected to a texturing treatment on its surface and is then formed with a ground surface layer essentially consisting of Cr, a magnetic layer essentially consisting of Co, a protective film layer and a lubricating layer. This substrate is used as a magnetic disk. The groove depth of the texturing having usually about 0.005mum Ra and 0.06mum Rmax is used. The recessed parts of the substrate are, therefore, not sufficiently textured and the texturing depth is nonuniform at the ruggedness of the substrate if the surface roughness Rmax of the substrate surface exceeds 0.03mum. The uniform texturing over the entire surface of the substrate is possible if the Rmax of the substrate surface is below 0.03mum. Consequently, the CSS characteristic and gliding characteristic of the head are improved, the reproduced output of the head is stabilized and the missing error characteristic is improved.
