Magnetic recording medium and a method for manufacturing such medium

摘要

A magnetic recording medium with improved friction and levitation characteristics and undiminished electromagnetic conversion characteristics, and a method for manufacturing such a medium, are disclosed. A magnetic recording disk substrate with Ni-P plated layers formed on both faces of an aluminum alloy substrate is given a texturing treatment using a grinding tape to form textures with a maximum cross angle within a range from 30 DEG to 50 DEG , and then a slurry grinding treatment to remove irregular protrusions generated during the texturing process is applied using freely moving polycrystalline diamond abrasive grains with an average size of about 1 mu m or smaller.
