Abstract

Stylus or needle for transcribing high frequency electric signals on to a recording tape or disc, is mounted in a (triangular ) tapered chuck bonded, e.g., with epoxy cements, to the face of a piezoelectric element, the opposite face of which is bonded to the apex of an inverted truncated tapered support connected to the arm of a recording machine. The interface between the major support and the arm is lined with a matl. with high damping characteristics. Esp. for part of a two-stage system for using audio-frequency recording techniques to record video frequency information, e.g., for play-back of television programmes.
