The disc we all use today to store digital data like pictures, songs, computer
games and more, was originally developed to store digital audio. The two
companys Phillips and Sony wanted to develop a way that people can listen
to high quallity music, The two other ways to listen to music, the record and
the cassette didn't provide the quallity that people wanted. The disc is a good
way to listen to music because it's easy to activate, it's cheap and it's small.
The disc is based on the gramophone record that was used to store audio,
It was the primary way to listen to music at most of the 20th century. The
recored and the gramophone that was used to activate it, was invented by
Emile Berliner in 1887.
