Abstract
PURPOSE:To form a recording medium having high-accuracy film thickness tolerance and good smoothness by providing grasping means which grasps a grinding tape with prescribed force into a grinding tape traveling path before grinding and subjecting the grinding tape to a calendering treatment. CONSTITUTION:The grinding tape 4 is delivered by clamping roller units 2 and, therefore, the grinding of a magnetic disk 1 is executed always at a stable traveling speed under the specified tension on a rubber roller 5 which is a pressing member even if there is a fluctuation in the tension state by a change in the winding torque or winding diameter of the tape 4 on a feed reel 8. Furthermore, the calendering treatment of the tape 4 is executed by the clamping roller units 2 and, therefore, the grinding surface of the tape 4 is maintained in the specified abrasive grain state and the specified grinding characteristic is maintained. The thickness of the magnetic film is thus obtd. with high accuracy and the good finish surface having less ruggedness is formed.
