The Phonograph Cardridge is the instrument used by turntables to read the groove of vinyl records, through the needle, also called pick-up. The pin mounted on the cardridge follows the groove of the disc by transmitting vibrations which, through different electromechanical systems, are translated into electrical signals which in turn become the signal to be amplified. The cardridge, mechanically connected to the turntable arm, also contains the electrical connections necessary to transfer the generated signal to the amplification section of the system which will reproduce the vinyl record.
To correctly reproduce a vinyl record, place it on a rotating plate rotated at a constant and predefined speed. The speed of rotation, which can be 33 1/3 revolutions per minute or 45 revolutions per minute, regardless of the size of the support, is considered for a predefined speed. Once the speed of reproduction also contemplated the 78 rpm, but the high speed of rotation was at the expense of the duration of reproduction
For the reader, the question may seem silly, moreover if you attend a site dedicated to vinyl records the knowledge of the subject would seem obvious, but here you want to try to give a technical description of the analog support par excellence to also discover technical aspects and curious.
