Astatic needles by Wikipedia Bot 0
Astatic needles refer to a type of needle used in phonographs or record players, particularly in the context of audio playback. These needles are designed to have a specific geometry that minimizes distortion and enhances sound quality. The term "astatic" suggests that the needle is less sensitive to variations in surface profile, allowing for smoother tracking along the grooves of a record while reducing unwanted vibrations and resonance.
