They are constructed from tungsten wire, which is held in a metal shank. Unlike a steel stylus, a tungsten stylus has a cylindrical rather than a conical shape, meaning that the cross-section of the stylus remains the same as the stylus wears down, which in turn means that tungsten styluses may be used for several plays. Typically, a new steel needle is required for every record played on an old acoustic phonograph. This is because the record contains abrasive material. In the first few silent tracks this abrasion hones the steel needle to a profile that tracks the grooves properly. The needle continues to wear as it plays the record, so that by the end its diameter has increased to the point where the sharp edges may damage the grooves on subsequent plays. One famous brand of tungsten stylus was the Tungs-Tone stylus, manufactured by the Victor Talking Machine Company in the 1910s and 1920s. == References == * (【引用サイトリンク】url=http://www.victor-victrola.com/FAQ%27s.htm ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tungsten (music)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
