タイラス。Information signals are detected and reproduced as changes in capacitance by relatively scanning concentric or spiral tracks on a disc-shaped recording medium made of a conductive material on which information signals are recorded as changes in geometric shape. In a capacitive video disk stylus, the front surface of the image is polished so that the sliding contact surface at the tip of the stylus body and the tip surface of the electrode form a certain angle α (assumed to be 0〈α〈). Video disc stylus.
