Find out how the CD came out, which turns 30 today

Exactly 30 years ago, on October 1, 1982, the first compact disc player, the famous CDs, arrived in stores in Japan. Called CDP-101 in honor of the binary code of zeros and ones, the 7.6 device kilos cost about R $ 4.3 thousand and was the gateway to one of the biggest revolutions that music has ever been through.

The product was the result of a partnership between Sony and Philips. In 1979, according to EFE, the Japanese and Dutch companies decided to come together to create a type of media that could take digital format to homes. Until then, the market was dominated by long players (LPs) and cassettes.

When the CDP-101 was launched, stores also received 50 different titles, made available by the record companies CBS / Sony and Epic / Sony. Among them were Mozart, Beethoven, Simon & Garfunkel, Julio Iglesias and Billy Joel’s “52nd Street”, considered the first album sold on CD.

Before, engineers from both companies had already worked on similar initiatives. Sony’s focus was on coding and reading; Philips’ was the optical system – which was introduced by the brand in 1975 with Laservision, a commercial failure.

Once united, they headed the first mass CD production at a factory in Shizuoka, Japan. But neither of them expected the format to be so successful.

What determined the size of the CD was the cassette tape, which was 11.5 centimeters. The problem is that in this format it would only be possible to record an hour of content, so Sony decided to increase it by five millimeters, moving to the current 12 centimeters, which support 74 minutes.

A study was made on the size of pockets in Asia, Europe and America to prove that the CD would be easy to carry. The answer came in numbers: in 1984, Sony launched the first portable player, the “discman” D-50, and two years later CD sales reached 45 million, far more than LPs.

The 100 million were reached in 1988, tripling in 1992. More than 200 billion CDs were sold in 2007, 25 years after its creation, but the format would begin to feel more and more pressure from the youngest, such as music players. MP3. In 2011, for example, production stood at 196 million, far less than the 330 million from ten years before.
