History and Future of Music Storage Methods
Music is all around us. It is interesting to see the progress of technology in music and how it has shaped our culture.
Wax Cylinders
Wax cylinders (vinyl) have 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 recorded onto a tin foil cylinder when the idea of a phonograph was first conceived. This was done by a diaphragm. The diaphragm captures the vibration of the soundwaves, which makes the needle (or stylus) imprint 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 then cause the needle to move, causing the diaphragm to vibrate, displacing the air and replicating the original sound.
Before the phonograph, invented by Thomas Edison in 1877, was the phonautograph by Leon Scott. I could record sound, however, not reproduce it.
Audiocassettes

Audiocassettes are a magnetic form of storing music. They proceeded vinyl records due to their compact design and lowered risk of being damaged. 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 over the tape and it would retain it’s data. The transmitter is an electromagnet, which is used to record the tape. There are two sides to a tape, each side containing memory for 2 channels (stereo).
The audiocassette is an easier and flexible method of storing data than that of the phonograph. A phonograph is easier to damage than the cassette because it is not protected against the elements of everyday wear and tear. Scratches damage the phonograph’s ability to playback the recorded data on the phonograph. 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.

Although Thomson set up the first electric system, it was Edison who invented the phonograph in eighteen seventy-seven. Editors at Scientific American, who were some of the first to experience Edison's newest creation, were startled. "The machine began by politely inquiring as to our health, asked how we liked the phonograph, informed us that it was very well, and bid us a cordial good night." (RCA Online 2)
The inner workings of the turntable may seem complex at first but after reading this paper it should become clear that, like all things, the record player works on basic principals of physics. In fact, the turntable is remarkable in that the basic physical principles behind it are quite simple. Some of these will be explored here. Please enjoy your visit.
Edison decided to change the idea by using a tin foil wrapped metal cylinder instead of the paper. The final cylinder phonograph had 2 diaphragm and needle units. One would be for recording date and the other would be for playing it. For the machine to work, one would have to speak into a mouthpiece and the sound vibrations would be imprinted on the cylinder. Then the recording needle would create some sort of groove pattern on the cylinder. The data can then played by back by the data from the created grooves.

The music industry is an ever-evolving revolutionary entertainment industry for the masses. Music provides entertainment to all different masses due to the variety of genres produced. Music is a very profitable and complex industry. Music has expanded to a worldwide industry for musical artist to express their art through the form of song to the masses. Music not only appeals to the ears but to every aspect of a person. Music allows for individuals to explore and let their imagination expand as they here a song. Throughout the years the industry has undergone dramatic changes. Whether it is genres, forms of how it is distributed, or even the impact the artist have had. The industry is diverse and ever changing as the years continue. In the past 20 years the industry has changed with help of the technological breakthroughs and adoptions.
With each passing year, technology has become highly involved in our lives, and continues to at a rapidly increasing rate. Technology, in many ways, was designed to help people in various fields of work. However, it has also achieved the reciprocal. Where does music lie? Has technology hurt or helped the field of music, specifically hip-hop? What do these advancements mean for the genre?
Music and the relationships of music have changed drastically in our society. The course of studies and the evaluations of the applications of the technology of music, the making and the listening of music have changed in the way we listen to music, the styles of music in our society and in the media. The importance of the technology in music today, has, over the past century been charted through the study of musical examples and through viewing how human values are reflected in this century's timely music. There are very many different types of music that are listened to. There are readings, writings, lectures and discussions on all the different types of music.
Physics is all around us, and yet we always overlook it. We see, hear or feel something happen but never stop to question why. Physics will tell us why. Music plays a part in everyone's lives. So much so that it is often overlooked and the technicalities of it are unappreciated. Sure there are times when we listen carefully to the music behind the songs we hear, we may focus on the rhythm or the harmonies, but we never think of what it took to make the sounds that we are hearing. In this paper, I will explain the physics musical instruments. I will describe and define sound in psychics terms and then describe how different instruments create their unique sounds.
... of the carbon microphone that make is so distinct from all other electronic sender tones. With the combination of the real sound of a voice passing through the carbon microphone fused with the technology we have today, the model that is created by Oksanen and Valimaki and used by a range of producers “incorporates a filtered noise source to model the self-induced noise generated by the carbon microphones” (Oksanen, Valimaki 27). With the scientific ability our world has today, we are able to recreate a sound that was first discovered over a century ago. The development of the carbon button microphone definitely makes a statement about our ever-changing technological society. Although it was an object invented many years ago during the Second Industrial Revolution, it has been altered and improved and has therefore left an everlasting impact on our society.
An audio Cassette also known as Music cassette (MC) uses a magnetic tape recording format to record audio. Audio cassettes come in two forms, either pre-recorded or blank and empty. The word cassette is a French word, which itself means a little box, rectangular in shape. A famous company known as Phillips was the first one to come up with the music cassette idea, but as time passed, its huge mass production was done all over the world. In order to listen to the music stored in these cassettes, one has to buy a Walkman or cassette player that are usually portable and can easily fit into a pocket and can allow people carry music around with them.
Simply, the read and write head is a ferromagnetic core. It can produce a variety of magnetic fields through a variety of currents. to write data onto the media in ASC2.
...big amount of collection. This is important in order to avoid any destruction or deterioration in the early stage of audiovisual archives. Every storage room must be equipped with suitable equipment, appropriate storage container and provide security enforcement to all repository storage.
The “head”, or device used to transmit data onto the magnetic disks, is an important part of the hard disk and composes most of the physics happenings. Current is passed through the head or in the physic’s case, the conductor, to produce a magnetic field around the conductor. This magnetic field then can influence the disk’s magnetic material. The head is driven by an electric motor, using electromagnetism, to exert pushing and pulling forces on magnets to the rotating shaft. In some cases the head moves to a required area on the disk, and the motion of the magnetized surface induces tiny voltage. This voltage is concentrated in the coil of the read head, and can be interpreted as the data stored on the magnetic disk. When the direction of the flow of electric current is reversed, the magnetic field’s polarity is reversed.
