Funny Holidays - CD Birthday

The CD's birthday is celebrated every year on March 2nd. It was on this day in 1983 that the world corporations Sony, Philips, and Polygram demonstrated to the public the first 12-centimeter disk on which Beethoven's 9th symphony was stored. The information was recorded using a special laser. Its duration was 70 minutes. At first, only audio files could be recorded. After some minor modifications, graphic objects, video files and other digital data began to be stored on media. The holiday, dedicated to compact discs, is the personification of achievements in the field of computer technology. At the end of the last century, rapid development of this area began. The emergence of a small storage medium was perceived by society as the greatest step towards a digital future. This device at one time became a real breakthrough in the music world. Most music lovers and popular composers decided to celebrate their professional holiday on March 2nd. Great musicians believe that it was discs that became the most powerful influence on the development of modern music. Cassettes and records faded into the background, giving way to innovative technologies. The first mechanical objects designed to work with sounds could not reproduce human voices. T. Edison created the phonograph, which led to the appearance of the famous organ-organ. The development of sound systems occurred very quickly. First the phonograph appeared, then the gramophone, gramophone, and tape recorder appeared. Over the course of several decades, humanity has gone from old phonographs to new compact discs. From 1978 to 1983, specialists from Philips, Sony, and Polygram actively worked to improve existing sound media. Floppy disks appeared in 1981, and CDs appeared in 1982, on which a lot of information could be stored. The name for the new development was chosen in such a way that it would be heard by all buyers. The Compact Disc had a round shape, a hole in the center, and was covered over the entire area with a thin layer of metal. The audio track is a spiral recess, information from it is read using a laser beam. In the UK, the first disc was released on March 2, 1983. And now, every year, music lovers celebrate the birthday of the CD on this date. The sensational event amazed the general public. CDs began to be distributed as music albums of favorite artists. Today, such information carriers are gradually becoming a thing of the past. Digital devices for working with files are rapidly replacing each other. Although in almost every home you can find a disk that may not be used, but takes pride of place on the shelf. In this regard, many musical figures do not forget to celebrate the holiday on March 2. After all, along with this format, the music came to life. ABBA's songs were recorded on Compact Disc, which became the first pop music album. At first, only audio files could be recorded. After some time, CD-R and CD-RW appeared for storing various data (photos, pictures, videos, and so on). CD-RW is a reusable device. The end of the last century and the beginning of the current one were a time of records in CD sales. By 2005, more than 200 billion discs had been purchased worldwide. Which is an average of about 30 disks for every inhabitant of our planet. But after that, the era of such digital devices began to decline. Memory cards are being replaced by flash drives.
