Abstract
PURPOSE: To lower and stabilize the friction between drum and tape, run the tape smoothly and prevent squeaking by vibrating the high frequency vibrating means of a head drum when dewing occurs in the head drum.
CONSTITUTION: The output signal from a dew detecting means 7 causes a high frequency signal to be applied between the electrodes 9a and 9b of the vibrating means 6 provided at the portion where the tape 4 of a stationary drum 1b contacts. This vibrating means 6 finely vibtates in its thickness in the direction changing according to the period of said signal. This enables the friction coefficient beween the tape 4 and drum 1 to be reduced and the friction coefficient in a dewing state to be put in an always stable state, thereby enabling the phenemenon of so-called squeaking to be averted and uneven running of the tape to be prevented.
