cutting stylus การใช้

Stereo recordings were made with a triangular cutting stylus.
Fortunately the cutting stylus never cut through the lacquer to the aluminum base.
A recording lathe and chisel-like cutting stylus like those used to record in wax would be used to engrave the groove into this lacquer surface instead.
Contrary to the Edison phonographs, the lateral recording method used a cutting stylus that moved from side to side in a " zig zag " pattern across the record.
Furthermore, the angle of the stylus, which used to be always sloping backwards, was changed into the forward direction, in line with the slope the original cutting stylus possessed.
