Abstract

PURPOSE:To reduce manufacture cost by forming the sliding cntact surface of a scanning stylus were a video disk comes into contact, the 1st side surface for regulating electrode width, and the 1st opposite surface for prescribing the upper edge of the 1st side surface while improving workability and manufacture yield. CONSTITUTION:A scanning stylus 14 has a stylus base 16 and an electrode. The stylus base 16 has an electrode-formed surface 17 where the electrode is formed, a couple of sliding contact surfaces 19a and 19b which come into contact with a signal groove, a couple of the 1st side surfaces 21a and 21b which extend longitudinally and specify the width of the lower part of the electrode below a prescribed value, a couple of the 1st opposite surfaces 22a and 22b which face the signal groove, a couple of the 2nd side surfaces 23a and 23b which extend longitudinally, and a couple of the 2nd opposite surfaces 24a and 24b which face the singal groove, and further has a couple of slanting surfaces 26a and 26b which permit the entry of a geometric change in shape on the signal groove.
