Shopping Guide - CD's

CD is the acronym for compact disc. It is currently the most popular means of storing digital data, mainly marketed music and computer software, in which case the CD is called CD-ROM. The technology used in CDs is similar to that one in DVDs

From the end of the 80’s and beginning of 90’s the invention of the compact discs promised greater capacity, durability and clear sound without noises, making the discs of vinyl obsolete.

Philips was the main company responsible for the creation / development of the CD-ROM. Then, other companies such as Sony and TDK came quickly in the new digital generation.

A CD is an acrylic disk on which is printed a long spiral. The information is recorded in holes in that spiral, which creates two types of physical irregularities: bright points and dark points. These points are called bits and make the information loaded from CD.

CDs: History and Trivia

According to the site "Museum of the Computer", the invention of the technology of the CD was born in the 60 through the experiences of James T. Russel. The compact discs have the capacity of 700MB and today it is used to store both music, until 80 minutes of recording, as data and files, known as CD-ROM. By mid-2005, the CDs still were known as the best way of marketing of music, so that the record companies joined it heavily to reach the consumer’s homes with their artists.. This scenario has changed dramatically in recent times, especially after the sharing of files in MP3 format took charge of the worldwide network of computers. Check and help with more information about the history of the CD and how it influenced the phonographic market world.

What is the most sold CD throughout history?

Actually there is no way to measure what is the most sold CD throughout history, since many works were launched in a period in which vinyl and CD still were together, but the American ranking (which already serves as a reference for what most are consumed in the world in recent decades) shows the leadership of a collection of the band Eagles- the one that sings the hit "Hotel California" - followed by pop star Michael Jackson with his contagious "Thriller."

When was released the CD-R and RW?

Until the late 80’s, CDs were recorded by the phonographic industry and there was no way to change its content. In the 90’s Philips and Sony launched the CD-R technology, which has allowed the world to make copies of discs. At that time, it was very common the drives "spoil” some copies until they could get a very “burnt” disc. But today this problem no longer happens that often. The CD-R discs can only be recorded once. In the early 2000 reached the market the CD-RW disk, which allows to be written and re recorded about a thousand times.

Why are classical music CDs always cheaper?

That is not quite true. What happens is that classical works such as Mozart, Bach or Beethoven, don’t need to have their copyrights paid, as their composers died a long time. Thus, some writers take the execution performed by orchestras not listed as the best in the world to launch cheaper disks. However, the classical music fans give preference for great maestros and orchestras-edge and they even invest good values to have CDs that can cost much more than the release of a band of rock.

What is the artist who sold more records in history?

Barbara Streisand. The North American singer have already amassed 63 million sold discs throughout her career.

Is there a quality difference between music downloaded through the Internet and the one recorded in CD by the recording industry?

That is a question that allows more than one answer, but let’s check in parts and so you can draw your own conclusions. First, we must notice that 99% of the songs you find on the Internet have a CD as a matrix that was recorded by a recording industry. Only this information would be sufficient to conclude that you can even find a music downloaded on the Internet with the same quality of a CD, but hardly superior. Another fact to consider is that the vast majority of the songs founds for download have bitrate of 128kbps, and any conversion of WAV (original format of the CD) to MP3 or WMA with bitrate below 160kbps certainly have less quality than the original.
