摘要： A polishing tape makes use of a foamed material such as polyurethane foam attached to a plastic backing material. The foamed material is elastic and some of its gas holes formed inside but near one of its surfaces are exposed externally. Because of its elastic nature, it can be deformed even if there are abnormally large abrading particles contained in a liquid slurry and such abrading particles do not become embedded in the target surface being textured. These externally exposed gas holes can also serve to absorb the debris generated by the texturing and to protect the target surface from being scratched thereby. Such a tape is used for a texturing process while dropping a liquid slurry containing abrading particles and rotating the disk substrate and pressing the tape against the target surface.

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 &mgr;m 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.

摘要： Polishing compositions with phosphoric ester added to a suspension containing abrasive particles can have an improved ability to have the abrasive particles dispersed again after they are left for an extended period of time such that the particles may have condensed into aggregates. Those with abrasive particles such as diamond powder dispersed in an aqueous solution containing a glycol compound, metallic salt of a higher aliphatic acid and phosphoric ester have an improved polishing ability.
