Music CD technology has a longer history that many people realize. Today you can download mp3 songs and music and make your own music CDs. Some music CDs can hold over 100 songs.
If not for the introduction of both the telephone by Alexander Graham Bell in 1876 and then the subsequent invention of the phonograph by Thomas Edison in 1877 the CD as we know it today would not exist.
In 1887 Emily Berliner took the phonograph one major step closer towards the CD by replacing the wax cylinder method Edison was using and replacing it with an audio disk.
It was not until over twenty five years later in 1915 the first seventy eight revolutions per minute record was introduced This technology allowed the mass consumer for the first time in history the ability to purchase a somewhat cost affordable record.
The next massive step closer to the music CD came in 1937 when a gentleman named Reeves invents Pulse code modulation. Pulse code modulation is the foundation for playing digital audio. Today’s computers and CD’s still use Pulse code to play audio.
Over the next two decades numerous advances including the introduction of the microgroove technology, which made possible the forty-five revolutions per, minute album. Another important introduction was magnetic tape, which allowed for much lager storage capabilities.
The big turning point came in 1978 when Philips invents and releases the first videodisk player. Philips also proposes a worldwide standard while attending the Digital Audio Disk Convention, which was held in Tokyo and attended by over thirty-five different manufactures.
In the mid 1980’s second and third generation compact disks were introduced and mass production of mass music CDs began.
As the 80’s continued massive growth in the sale of Cd’s occurred to the point in the early 1990’s over twenty eight percent of the United States population owned a CD player. Over the next fifteen years the sale of music CDs has far surpassed the sale of vinyl records and has set the stage for newer longer and higher quality CD’s and DVD’s We are not sure what the future holds for music CDs but we know it will only get better.
