SUBSTRATE FOR MAGNETIC RECORDING MEDIUM, METHOD FOR MANUFACTURING THE SAME, AND MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a substrate for a magnetic recording medium on which the magnetic recording medium can be formed achieving electromagnetic conversion characteristics and the floating characteristics of a recording head at a high level. SOLUTION: The substrate comprises a disk-shaped non-magnetic material and its surface has a plurality of texture marks of which the peripheral direction components and radial direction components change continuously. The at least four kinds of continuous changes exist and cross angles are formed by the respective texture marks obtained by the respective changes and thereby at least the four kinds of the cross angles as a whole are formed on the substrate.
