What Is The Stylus

The stylus is connected to a little piece at the end of the tonearm called the phono cartridge. The stylus is a small metal tube  underneath the cartridge as the stylus or needle. It is a crucial part of the phono cartridge as this is the only part that touches the record groove. In most cartridges particularly Moving Magnet types, the stylus is user replaceable. In moving coil designs, the whole cartridge needs to be replaced or sent back to the factory for re-tipping. Some including Ortofon offer a change-over service which means you trade-in your old model for the same or better.

The stylus is actually made up of three parts. There is (1) the stylus itself which is usually a diamond, although there are both man-made and natural diamonds in use. The stylus is (2) mounted at the end of a short arm called a cantilever that 'moves' as the stylus traces the record groove. The cantilever is fastened to (3) the phono cartridge. 

Stylus Types: A stylus can come in a number of shapes and sizes. The best styli try to duplicate the shape of the cutting stylus used to produce the original master recording. For these types, you will see such terms as MicroLine, Fineline or MicroRidge.

Conical/Spherical Type: The conical/spherical stylus was until the mid 1980's the most widely used stylus. This was because it usually came as an original part of a standard turntable. It is the simplest and least expensive among all of the styli shapes. Its spherical tip, typically with a radius of 0.7 mm, touches the centre of the groove walls. The conical stylus can be found with lower to moderately priced turntables.

Elliptical Type: The elliptical stylus has two radii, with the front being wider than the side radius. Elliptical styli are available in several sizes, such as 0.2 x 0.7 mm, 0.3 x 0.7 mm and 0.4 x 0.7 mm. The first number is the side radius. The smaller the side radius, the better its music retrieval potential.

Shibata & Fineline Type: Another stylus that is reserved for the higher priced models is the Linear Contact (LC). This type of styli provides a vertical contact area several times more than that of the elliptical, thus enabling it to respond to minute grove modulations. Back in the late 1970's, the shibata type also became popular. It was designed for CD-4/quadraphonic records, but performs brilliantly on stereo records.

The Future

For older cartridges, it may be advisable to purchase at least two replacement styli. Manufacturers have been phasing out many replacement styli through the years and so the next time you need one for your older cartridge you may not be able to find it.
