摘要： The method for testing burnishing tape includes placing the tape on a backing surface and applying a force normal to the abrasive surface of the tape in a localized area of the tape surface. Thereafter, an increasing pulling force is applied to the end of the tape up to a point where the tape moves under the effect of the normal force. Through prior burnishing tape product testing a known normal force N is determined and a delamination pulling force D is likewise determined, such that a burnishing tape can be said to be defective where it is placed under a normal force N and the pulling force required to move it is less than the delamination pulling force D. The values of N and D are determinable for different types of burnishing tape and thereafter utilizable to test further quantities of similar burnishing tape. The testing device of the present invention includes a tape supporting plate, a force gauge for applying a known normal force N to the abrasive surface of the burnishing tape disposed on the plate, and a variable torque motor with a torque sensor that is utilized to apply a known variable pulling force to the tape, such that the pulling force required to move the tape under the normal force N can be determined and then compared to the predetermined delamination force D. Where the pulling force required to move the tape is less than D the tape is determined to be defective, whereas when the pulling force required to move the tape is greater than D the bonding strength of the abrasive layer of the burnishing tape is determined to be adequate such that the burnishing tape can be confidently utilized to burnish hard disk surfaces.
