Abstract
PURPOSE:To smoothly execute reproducing, FF and REW operation by setting up the average roughness of the center line of a smooth sheet on the upper half side to a value smaller than that of a smooth sheet on the lower half side and reducing the frictional coefficient of the sheets. CONSTITUTION:The average roughness (Ra1) of the center line of the transparent smooth sheet 14 on the upper half 5a side and the average roughness (Ra2) of the center line of the smooth sheet 15 on the lower half 5b side are set up to Ra1<Ra2. Since the frictional coefficient of the sheet 15 on the lower half side is smaller than that of the sheet 14 on the upper half side, torque at the time of traveling the tape 2 having comparatively small tensile force and capable of easily traveling while being stuck to the surface of the sheet 15 can be sharply reduced. Consequently, reproducing, FF and Rew operation or the like can be smoothly executed. The average roughness of the center line is preferably set up to Ra1<=0.15mum and Ra2>=0.2mum (Ra1/Ra2<=0.75) and Ra1<=0.06mum and Ra2>=1.0mum (Ra1/Ra2<=0.06) are more preferable.
