METHOD FOR FORMING HIGH ORDERED ALUMINUM ANODIZING OXIDATION HOLES AND METHOD FOR FORMING MAGNETIC RECORDING MEDIA USING THE SAME

摘要

A method for forming high ordered aluminum anodizing oxidation holes and a method for forming magnetic recording media using the same are provided to form high ordered nano-holes regularly by controlling the formation position on the aluminium layer through a guide pattern. A method for forming high ordered aluminum anodizing oxidation holes comprises a step of selectively forming a guide pattern(14a) for guiding the forming position of anode oxidation holes formed during anode oxidation by selectively blocking aluminium area exposed on an aluminum layer(12), and a step of regularly forming a plurality of nano-holes in which alumina is formed on the outside surface by performing anode oxidation on the exposed aluminium area and controlling formation position of nano-hole(12b) according to the kind of the guide pattern masking the exposed aluminium area.
