Here’s a neat image of a record and a stylus at 1000x magnification. It’s pretty incredible to see the etched grooves on the record up close and how they interact with the needle.
A stylus, or record needle, is one component in a transducer – a device that converts electrical energy into mechanical energy (or vice versa). In the case of a record player, this transducer is a cartridge – composed of a stylus, cantilever, magnets, coils, and body – which converts the mechanical energy of the recorded vibrations into sound waves, which are amplified and broadcast through speakers.
The stylus’ job is to read all the information in the grooves, which were originally created using another needle as part of a transducer – in this case, converting the electrical energy of the sound waves into vibrations etched into the record grooves. In a stereo record groove, the right channel is recorded on the right wall, and the left channel is recorded on the left.
