Needle playing a record, SEM

Needle playing a record. Coloured scanning electron micrograph (SEM) of the needle (stylus) of a record player in a groove on a record. A record is used to store sound. It is produced by a machine with a head which vibrates in time to the sound being recorded. This cuts a groove in the record which varies according to the vibrations. A needle can then reproduce these vibrations as it runs along the groove and these, when amplified, produce the original sound

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate details of a needle playing a record. In this coloured scanning electron micrograph (SEM), we are granted an up-close view of the stylus delicately nestled within a groove on a vinyl record. Records, as we know, serve as vessels for sound storage and playback. This image beautifully captures the essence of this technology by revealing the inner workings of a record player's needle. The machine responsible for creating these records employs a vibrating head that cuts grooves into them in perfect synchrony with the recorded audio. As our eyes trace along the path etched into the vinyl, it becomes evident how this seemingly simple process holds immense complexity. The needle's role is pivotal; it faithfully reproduces each vibration encoded within those grooves, ultimately giving birth to familiar melodies when amplified through speakers. The false colours employed in this SEM add an artistic touch to an otherwise scientific image, enhancing its visual appeal while preserving its informative nature. Through this photograph, we gain insight into both acoustics and technological advancements in music reproduction. Science Photo Library has once again captured an extraordinary moment frozen in time—a testament to their commitment to showcasing science's beauty and intricacy through stunning visuals like this one.
