Who invented the CD player? Who invented CD?

The CD player was invented by Sony.

Although Sony launched a CD player as early as 1982, it was too expensive for few people to afford. In 1983, other companies launched CD players one after another, and the situation was very good, but this was only temporary. Most people are still addicted to the world of vinyl.

It wasn't until 1984 that Sony released a portable CD player that it successfully entered the era of CD player popularity. Nowadays, there are fewer and fewer CD players.

Invented the CD player two companies Sony and Philips, how their CD sounds.

In 1982, the world's first CD** player, which was also the first CD** produced by Sony, was born. Since then, CD players and CD culture began to be widely popular in the world, from the 80s after the reform and opening up, the 90s is the era of CD popularity in China, but after 2005, with the development of computers and the Internet, CD gradually withdrew from the mainstream of history.

On the evening of August 31, 1982, Sony CBS Sony Netherlands Philips and Polygram jointly held a launch event for the digital recording format of CD, and decided to release it in Japan from the fall. With a diameter of only 12cm, it records loss-free digital signals and is non-linear**, which means free and fast song selection. Capable of semi-permanent use, the CD has come true to the dreams of many music fans.

In addition, on October 1, 1982, Sony Corporation launched its first CD player, the CDP-101, which was priced at nearly 170,000 yen, which was difficult for the average consumer to accept. After entering 1983, CD players from other companies were also launched one after another, and the sales situation was very good. However, sales stalled for a short period of time, and it turned out that the people who bought the CD system at that time were mainly Hi-Fi enthusiasts, and most of them still preferred LPs that had been integrated into their lives.

In the United States, the VHS cassette is also a standout, and people can't find a reason to replace him. In order to save this decline, Kozo Osone of Sony's audio division led his subordinates to develop the D-50, a product with a thickness of about 4 CD cases, which is the ancestor of modern portable CDs.

The earliest CD (compact disk) was published in 1980 by Philips and Sony, which was originally designed for the consumer market of home appliances, and I did not think that CD could be used for computers in the future, because at that time there was not even a 286 computer, and the data storage of computers was still in the stage of inches of magnetic sheets, and even inches of disks had not yet been invented.

Before the invention of CD, the sound system is analogous, most of them are 30 cm diameter LP records, radios, and tape recorders, etc., there was no digital sound before the invention of CD, so CD can be said to be the greatest invention since the relay crystal.

Since the advent of CDs in the audio market, 30 cm diameter analog LP records have slowly faded away (although there are still a small number of die-hard audio fans who have never given up on traditional analog records, but that is only a small part after all). Since the invention of CD, all similar products related to CD, including ***, are derived from it.

CD drive began in 1980, by the Dutch Philips company and Japan's Sony published ** optical disc (audio CD), also known as CD-DA (digital audio), since then, due to the development of other ** markets and a series of disc specifications and products!

I saw someone in front of me who said that those who like vinyl records belong to the "die-hards", and it is polite to say that this kind of person has no ** cells at all.

Raw. Since then, CD players and DAOCD culture began to be widely popular in the world, from the 80s after the reform and opening up, the 90s is the era of CD popularity in China, but after 2005, with the development of computers and the Internet, CD gradually withdrew from the mainstream of history.

The CD player is actually what we often call a CD** player in our daily life, and some people call it a laser record player or a laser record player. It is an intelligent high-fidelity stereo sound device controlled by microcomputer, which adopts advanced laser technology, digital technology, computer technology and various new components, and has the advantages of high-density recording, long playback time (up to 60 75 minutes), easy operation, and fast song selection. It can realistically reproduce the recorded content, with clear layers and a sense of presence.

Its acoustic technical indicators are very high, the dynamic range is large, the frequency response width is up to 5 20000Hz, and the distortion is small. At present, CD** device is already a very common audio ** equipment, according to its shape can be divided into desktop and portable two. The most famous portable CD players are Sony, Panasonic, etc.
