Abstract: A magnetic disk includes two kinds of texture lines formed on a substrate rendered to texturing, one kind being formed over the entire substrate and parallel with a circumference of the substrate and the other kind being formed such that a line tangent to the other texture intersects a line tangent to the one texture at an angle of 3 to 9 degrees. The other texture lines are yielded by processing the substrate with a polishing tape rocking the substrate radially thereof, and satisfying the floating characteristic of a magnetic head as being floated in a low degree, the contact-start-stop characteristic, and the attraction characteristic.
