ABSTRACT:
A head for recording an information signal in and reproducing the same from a semiconductor recording medium comprises an electrode stylus for recording and reproducing recording information by relatively sliding on the semiconductor recording medium, the recording information being recorded and reproduced through the electrode stylus, and a nonconductive supporting substrate, provided on the side surface of the electrode stylus, for supporting the electrode stylus. A hardness of the electrode stylus is lower than a hardness of a surface medium which constitutes the semiconductor recording medium and is higher than a hardness of the supporting substrate.
