What does "Burning a CD" mean?


If you have never encountered a recorder CD, you may not know what the term "burning one" means CD». It is dangerous; Do you need a lighter?

Let's explain to new users how the process of burning one works CD, because it is called "burning" and let those who were active in the late 1990s remember their youth.

Burning means recording a recordable CD with laser
The burning of one CD means to burn data to a recordable compact disc (called “CD-R ”for short), with a special device called CD burner ή CD-R drive. The process is often called "burning" because of a laser on the unit CD-R uses heat to record data to disk.

For about a decade from 1996 to 2005, many computers were sold with built-in drives CD-R, so that users can back up their data, share digital photos with others, create CD audio and more. At some point CD were made DVD, but with the advent of USB flash drives and the internet, registration CD became a less popular way of storing and transferring data. But during this time period, the registration CD was very common.

In our internet search, the term "burning one CD» first appeared around 1993, when technology CD-R began to become quite affordable for professional use. But the term "burning", which means "registration", precedes CD-Rs. In particular, the phrase "burn an EPROM»Was common before CD and the term probably extends to technology even before that.

How does one work CD-R;
Do not be afraid and you will not set fire. When registering a CD, nothing literally burns (as in fire), but a chemical layer on the disk changes with the heat of the laser. To understand, you must first know how a normal one works CD.

In a normal CD mass production, the data is stored as binary data in a series of natural pits and flat areas (or lack of pits) in a special layer on the disk. To read one CD, one CD player sends a laser beam along a spiral notch embedded in the data layer of the disc. If the laser beam is reflected back due to the flat area, the player records the point as a "1." If the laser beam hits a dent and is reduced or deflected, it is recorded as "0".

The disadvantage of CD mass production is that the 1980D data layer (cavity and flat areas) is permanently sealed to disk and cannot be changed later. But in the mid-XNUMXs, scientists at Taiyo Yuden in Japan discovered that no real dimples were needed to diffuse laser light. Instead, you could incorporate a transparent chemical layer into the disk that will darken when heated by a higher power laser.

This is how it works CD-Rs. So instead of dents in a commercially compressed CD, The CD-R use dark areas that "burn" on the disk.

The cost of CD-R decreased rapidly
The first commercial units CD-R appeared in 1988 by Taiyo Yuden in Japan, but the first ones we found while searching the internet were from Optical Media International, which released in 1989 and cost $ 150.000 (about $ 324.000 today).

The Topix CD burning system Optical Media International included a complete supercomputer installation, as standard desktops did not have the storage, software, or any of the necessary materials to do the job. (In 1989, a standard desktop hard drive stored 20 or 40 megabytes and a CD-ROM could hold 650 megabytes.)

The cost of registration systems CD-R decreased dramatically, entering the game the Meridian costing $ 98.000 a few months later, and with a system from Sony that cost $ 30.000 in 1990. Finally, in 1995, when consumers could buy a Hewlett-Packard CD-R for less than $ 995The CD-Rs started to become mainstream. The speed in units CD-R also increased over time, and by 2002, one drive CD-R 52x could burn an entire CD in less than three minutes.

As the units CD-R became more common, the cost of media CD-R also decreased dramatically. In 1990, the CD-Rs cost about $ 100 per piece. By 1996, they cost about $ 10 per record. In 1999, it was about $ 1 each. And only a few years later, you could buy in bulk CD-R for a few cents per disk.

People also used the CD-R for piracy, both in commercial piracy, and also for personal use, and the rapid fall in the price of media CD-R, fed this trend significantly.

The burning of one CD-R was part of our culture
As the disks CD-R became cheaper and cheaper around 2000, its adoption CD-R increased rapidly. People began to use them as a method of transferring data between computers, and the youth of that time often used them to make custom CD Music.

Similar to mixed cassettes, where people recorded favorite songs on the radio or other media, in a customized order to suit specific moods or to share their personal taste in music with friends, something similar appeared with the CD in the late 1990s. In the case of CD mix, people usually copied (“rip”) pieces from existing ones CD on a computer (or downloaded from Napster) and then burned to a custom one CD-R containing tracks in the order they selected.

With the rise of digital music players, the CD mix began to lose ground in the mid-2000s, in favor of custom playlists on iPod or smartphone.

You can even burn one CD today
While the CD-R is definitely not as popular as it used to be, companies still sell CD-Rs, as well as the following technologies, such as CD-RW, DVD-R, DVD+ R, DVD-RW, DVD+ RW, blu-ray etc. And if you have a unit CD-R or DVD-R, you can still register one CD-R or DVD-r.

Why would you want to do that? Some vintage computer users use CD-R for data transfer between their machines, some others use them to listen to songs in an old car that has CD player that does not support Bluetooth connectivity and more.

But if you do, keep in mind that science has shown that CD-Rs (and their rewritable cousins CD-RW) is not a capable archival storage medium. Many records CD-R that burned in the 1990s and early 2000s are illegible today, due to their low quality.

The future of burning technology
Strange as it may seem, burning a blu-ray disc right now is probably the safest way to keep a backup of your data. There are even companies, such as Verbatim, which they report that your data will be stored for 1000 years. So it seems that the "burning of a medium" has deep roots and that it does not intend to give up so easily.
