What a stylus is
The stylus is the very small tip at the end of a record player’s tonearm that sits in the record groove. It is the only part of the player that physically touches the record surface, and it follows the groove’s microscopic wiggles as the record spins.
Stylus vs needle vs cartridge
These terms get mixed up:
- Stylus: the tip that touches the groove. It is usually mounted on a thin support called a cantilever.
- Needle: an informal, older word for the stylus. In everyday speech, “needle” and “stylus” mean the same thing, although a modern stylus is not a sharp needle.
- Cartridge: the assembly that holds the stylus and cantilever and converts their movement into an electrical signal.
On many turntables you can replace just the stylus assembly, while on others you replace the whole cartridge. See the parts of a record player for where each sits.
What the stylus does
As the record turns, the stylus rides in the groove and is pushed side to side and up and down by its walls. That motion travels along the cantilever into the cartridge, where it is converted into a small electrical signal. The signal then goes through a preamp and amplifier to the speakers. The whole chain is described in how a record player plays music.
Because it must follow very fine detail while pressing lightly on the vinyl, the stylus is made from hard materials. We cover them in what record player needles are made of.
Stylus shapes
Manufacturers describe the tip’s shape, which affects how it contacts the groove. Common names include:
- Conical (spherical): a rounded tip, common on entry-level cartridges.
- Elliptical: a narrower profile that can follow finer detail.
- Shibata, hyperelliptical and other advanced shapes: designed to make more contact with the groove wall.
- Microline or micro-ridge: a very fine shape used on higher-end cartridges.
More complex shapes tend to cost more and can be more demanding to set up correctly. Match the stylus to your cartridge, since styli are generally not universal.
How record players work without electricity
Early mechanical phonographs and gramophones had no electricity. The stylus vibrations were passed to a diaphragm and a horn, which made the sound loud enough to hear. Modern electric turntables use a cartridge, preamp, amplifier and speakers instead. A modern player without power will not produce a useful sound.
How long a stylus lasts
Stylus life depends on the material, tip shape, tracking force and how clean your records are. Manufacturers often quote figures in the range of hundreds of hours, and some higher-quality styli are rated for more than that. Treat any number as a rough guide and check the maker’s guidance for your model.
Signs of a worn stylus
- Distortion, especially on loud passages or high-pitched sounds
- A dull or muffled sound
- Mistracking or skipping that was not there before
- Audible crackle that persists across several clean records
Worn styli can also damage records over time, so replace one when you suspect it is worn. If you are unsure, a dealer or a magnifier inspection can help.
Cleaning the stylus
Dust and fluff can build up on the tip and affect sound. Common approaches include a dedicated stylus brush, used gently from back to front, and cleaning solutions or gels sold for the purpose. Avoid pressing hard and avoid pushing sideways, since the cantilever is fragile. Follow the instructions of the cleaning product and your turntable manual.
What can damage records
Record wear and damage commonly come from a worn or dirty stylus, an incorrectly set tracking force, dust and dirt on the surface, scratches from careless handling, warping from heat, and poor storage. Keeping the stylus in good shape and the records clean helps all of these.
