STYLUS
Text: Stylus is the modern term for what used to be called needle in old-style phonographs. Unlike the short-lived steel needles used with old 78-rpm records, the modern diamond-tipped stylus is precision-ground and flexibly suspended so that it easily follows the contours of the record groove without damaging the disc or distorting the sound.
