History and Future of Music Storage Methods :: Audio Technology Essays

History and Future of euphony Storage Methods Music is all around us. It is interes ting to see the go on of technology in music and how it has shaped our culture.Wax CylindersWax cylinders (vinyl) nominate a mechanical method of recording and playing music. The data on the cylinder is stored linearly. It senses the transducer signal (vibrations) of the record and transmits it to a diaphragm. Sound was record onto a tin foil cylinder when the idea of a phonograph was introductory conceived. This was done by a diaphragm. The diaphragm captures the vibration of the soundwaves, which makes the needle (or stylus) take form a mechanical form of the soundwave in an analog form onto the tin foil. When playback is desired, the impressions left on the tin foil from the original sound would accordingly cause the needle to move, causing the diaphragm to vibrate, displacing the air and replicating the original sound. forrader the phonograph, invented by Thomas Edison in 1877, was the phona utograph by Leon Scott. I could record sound, however, non reproduce it.AudiocassettesHowstuffworks.comAudiocassettes are a magnetic form of storing music. They proceeded vinyl records referable to their compact design and lowered risk of being injured. Cassettes are recorded linearly. Unlike the vinyl record, it uses a ferromagnetic substance to create a magnetized medium on the tape. It was popular because of its simplicity, one could record everyplace the tape and it would retain its data. The transmitter is an electromagnet, which is used to record the tape. on that point are two sides to a tape, each side containing memory for 2 channels (stereo).The sound recordingcassette is an easier and flexible method of storing data than that of the phonograph. A phonograph is easier to impose on _or_ oppress than the cassette because it is not protected against the elements of everyday wear and tear. Scratches damage the phonographs ability to playback the recorded data on the pho nograph. However, the audiocassette is prone to other types of damage than the phonograph. If left near a magnetic item, the fidelity of the data in the cassette may be at risk.This electromagnet is tiny - perhaps the size of a flattened pea. The electromagnet consists of an iron core wrapped with wire, as shown in the figure. During recording, the audio signal is sent through the coil of wire to create a magnetic field in the core. At the gap, magnetic flux forms a fringe pattern to bridge the gap and this flux is what magnetizes the oxide on the tape.
