A magnetic cartridge is one important component of a record player since it is used for the recordings of analog sound playback which are also called as records. But now, the common name for this is turntable. Other terms used before are phonograph and gramophone. Cartridge is known also as pick up and it is a type of device which is electro mechanical that will convert vibrational to electrical energy. The electrical signal that the cartridge has created is amplified and is converted by loud speakers to sound.
Other components of this are the body, coils, magnets, cantilever, and styluses. The stylus is mounted and its purpose is to contact with the record groove. Styluses are often made from small polished diamonds or some industrial gemstones. The cantilever will be supporting the stylus while transmitting vibrations to the assembly of magnet or coil. Old cantilevers are made from aluminum or from boron. Other types of turntable cartridge contain styluses and cantilever that are detachable, making it as an advantage, resulting to no more replacement of cartridges when the styluses worn out.
Cartridges have different kinds of variations in dissimilar in size and shape. The two most known technology principles which serve as power of the types are the moving magnet and the moving coil. Moving coils have advanced designs and are expensive unlike moving magnets. Other types of MC have designs which are cheaper but may have low quality sounds.
For magnetic cartridges, the cantilevers are always carrying permanent magnets located between two fixed coils in a form of electromagnetic generator. If the magnet responses to stylus through vibration, it will be inducing some current. And because magnets are small and have little mass, it will not be connected mechanically to its generator and the adjusted styluses follow grooves and are demanding less tracking force.
The induced magnetic types and also iron types have ferrous alloy or pieces of iron that moves. Instead of coupling magnets, these two materials are connected to its cantilevers. The permanent and the bigger magnet is positioned above the coils that provide a needed magnetic flux.
The MC cartridges design is an electromagnetic generator. Unlike the MM design, the coils and the magnet are arranged in a reverse manner. The coil is attached to the stylus and it moves within the constant magnet. A coil is made from a very fine wire and are mostly tiny. However, there may also be some MC cartridges in which the output is the same with the MM cartridges.
Another type is the moving micro cross cartridge. This MMC design is considered as one variation of MI design. Both the magnets and the coils remain in place while the micro cross will be moving with the stylus.
And the last type is London Decca Cartridge. London Decca has unique designs and contains fixed magnets and fixed coils. Styluses contain diamond tips, having a short iron, and cantilever is shaped like an L made of steel that is non magnetic.
The short iron is positioned so close to stylus tip, resulting to a very accurate tracking of motions. Positive scanning is what the London Decca engineers call the tracking. This is a type which may be very musical but earlier versions need more forces of tracking.
