Method of texturing and agent therefor |
摘要 |
An agent used for texturing a surface of a substrate for a magnetic disk includes an aqueous solution containing a glycol compound serving as surfactant in an amount of about 1-25 weight % and agglomerated polycrystalline diamond particles with average diameter of 0.01-2 mum in an amount of 0.001-3 weight % formed with very small polycrystalline diamond particles with average diameter of 1-20 nm. When the substrate surface is textured, the substrate is rotated, the agent is supplied to the target surface to be textured and a polishing tape is pressed and run against it. A substrate thus processed has a surface with very fine and uniform textured lines without any abnormal protrusions. |
