What Is a CD-R(Compact Disc Recordable) and How Does It Work

Overview of CD-R

What does CD-R mean?

CD-R is the abbreviation of Compact Disc Recordable.

What is a CD-R?

It is a digital disc storage format.

The CD-R disc is a bang out of disc that can be written once and read many times.

By 1992, the cost of a typical recorder fell to $10,000-12,000.

In September 1995, Hewlett-Packard launched the 4020i model manufactured by Philips at $995.

Now, lets talk about the lifespan of CO-R.

Practical tests have shown that even with normal storage, certain CD-Rs can degrade rapidly.

The quality of CD-R discs has a large and direct impact on lifespan.

You should not expect that low-quality discs can be used for a long time.

According to research conducted by J. Perdereau, the average life expectancy of CD-R is 10 years.

Branding is not a reliable guide to quality, because many brands do not make their discs.

Instead, the CD-R discs come from different manufacturers of varying quality.

The last part is about how CD-R works.

CD-R discs are coated with photosensitive organic dyes, allowing you to record information.

After the CD-R disc is inserted into the computer, the recording process begins.

The laser inside the drive heats the dye to show areas that scatter light like traditional CD pits.

The CD-R drive does not create pits on the CD.
