Abstract :
Magnetic alumite disks were fabricated using an anodic oxidation method. An additional chemical texture process was effective in improving tribological properties. The recording characteristics of 10-, 20-, and 30-nm-textured disks were evaluated. A recording density of 50 kb/in was attained at 5 MHz and 5 m/s relative speed. Environmental tests were carried out, with excellent results
