ABSTRACT:
A manufacturing method, for an abrasive tape used for the burnishing of items such as floppy disks, which significantly reduces resulting scratches. An abrasive tape is manufactured by the steps of applying a coating liquid which contains as a major composition abrasive particles and a binder resin to a flexible substrate; drying the flexible substrate to produce an abrasive layer; and subjecting the abrasive layer to a surface smoothing treatment in order to align the tip ends of the abrasive particles to a uniform position by passing the abrasive layer between pressure rollers in such a manner that the flexible substrate comes in contact with an elastic roller, whereas the abrasive layer comes in contact with a metal roller, and wherein the pressure rollers are composed of the elastic roller having a hardness of 50-80 measured by a spring type hardness tester A and the metal roller, and are arranged opposite to each other.
