1.Analyses and eventuate previous and current recording formats :
In half of 19th century people knew that sound waves are more or less dense portions of the air reaching to the human ear. But in 1857 being used phonograph constructed by Leon Scott of France. He was the first person on the world who record phonograph sound. Scott's machine was made from tubes, membrane and paper coated with soot cylinder .When you turn the sound trough the tube the vibration moved membrane through which the needle quivered leaving a trail on a rotating cylinder slowly. But the Scott's phonograph never had wider application . That's why 20 years later in 1877 , American Thomas Alva Edison invented a method that allowed for the practical application of the phonograph . In practical method of using phonograph you could record and hear the voice or the sound normally . Edison changed phonograph - cylinder was covered with wax or tinfoil . On the beginning phonograph was powered by hand , after that by spring and on the end by electric . Edison machine was constructed from conical tubes, aiming to strengthen the sound, and the membrane attached to the stylus, which were at the bottom of this tube - the stylus vertically stressed the shallower, the deeper the groove on the surface of a metal cylinder coated with wax, and later in the film zinc thus perpetuating a sound wave .With a very simple solution to a mechanical cylinder moved during rotation along its axis by a constant amount relative to the stylus. Playing back recorded sound was to place the stylus in the groove channelled, and then putting the cylinder in rotation. The stylus with a membrane attached to it move respectively to previously notched groove composed of depressions and elevations. These vibrations transmitting the stylus bonded to the membrane, which resulted in moving the movement of air particles. These particles hit the walls of the tube bouncing up and strengthening, and finally reached the ears of the listeners.
Thomas Alva Edison was the first person who recorded first singing voice, song called ''Mary had a little lamb'' . Phonograph had lots of defects . First one was the sound - was really quite and not very pronounced .
The wax cylinders after few records just clashed . They tried to solve the problems , and they done it in 1897 . Emil Berliner was who solve it and instead of using cylinders used round wax-coated zinc plate . He used something different than Scott and Edison ; method of forming a lateral groove. His phonograph was working almost this same but however, he applied a special arrangement of levers that move the stylus across instead of vertically. Which make the surface undulating groove .Berliner was as creator of CD pressing. In 1894 he open his first phonograph company : ''The Berliner Gramophone Company'' . Straight after moved the recording and production of gramophone records. In 1909 on the appeared the double side CD's , there were produced synthetic resin or shellac CD's. In 1924 people used first time microphones to record a sound on CD and year after normalized speed of record to 78 rpm. On this time were using mid line cd from this days and from today - 7'' , 10'' , 12'' . You could record the sound on it till 5 min . In July 48' company called ''Columbia'' as a first on the world introduce long-playing CD - LP. Those CD could record the sound till half an hour on both sides and the mid line of them was 12'' and were played with speed of 33 and 1/3 rpm . In 1958 ''Columbia'' presented first stereo CD .
In the end of 80's all metal, wax, shellac, vinyl, magnetic tape was replaced by compact disc with revolutionary digital audio recording and image playback using laser beams. There have been lots of changes :Originally used for sound recording discs replaced the metal rollers made of wax, zinc, and then shellac, vinyl and finally dynaflex . Along the way, for a time, enjoyed popularity magnetic tape / cassette / until we got to the point in the history of the recording industry, the dominant sound carriers have become board with digital recording - CD, CDR, DVD .
