CD-R/RWs are available with capacities of 80 minutes of audio or 737,280,000 bytes (700 MiB), which they achieve by molding the disc at the tightest allowable tolerances specified in the Orange Book CD-R/CD-RW standards.
How many GB is a CD-R?
Expressed in binary notation (as is typical with CD-R, CD-RW and most operating systems) the same disc has a capacity of roughly 4.38 GB [4:700,000,000 bytes ÷ 1024 = 4,589,844 KB ÷ 1024 = 4,482.27 MB ÷ 1024 = 4.38 GB] . How much information can actually be stored on writable DVD discs?
What is the largest capacity CD-R available?
The largest CD-R discs manufactured are 99-minute CD-R discs. For storage, these discs are capable of holding up to 870 MB of data.
Does CD-R permanently store data?
CD-R, CD Recordable: This is a WORM (write once, read many) device. Once you write data onto the CD, the data is permanently stored. CD-RW, CD Rewritable: These CD disks are actually rewritable. You can store data on a CD-RW disc, erase it, then store different data on the disc.
How much memory can be stored on a CD?
A standard 120 mm, 700 MB CD-ROM can actually hold about 703 MB of data with error correction (or 847 MB total). In comparison, a single-layer DVD-ROM can hold 4.7 GB (4.7 × 109) of error-protected data, more than 6 CD-ROMs.
Are there blank DVDs larger than 4.7 GB?
Digital video discs (DVDs) aren’t like hard drives that are available in more or less any capacity you want. There are only two sizes of DVDs: a 4.7GB version and an 8.5GB version.
What is CD size?
A standard compact disc (CD) is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inch) thick.
Which is better CD-R or CD-RW?
After storing data it is converted into CD-ROM. It is made of a reflective metal disk with layer of green or opaque dye on top. It is cheaper as compared to CD-RW and CD-ROM also. In CD-R data can not be written over.
Difference between CD-R and CD-RW :
|All CD players i.e. older and newer can read CD-R.||Older CD players can not read CD-RW.|
Can a CD-R record video?

What can I play a CD-R on?
Once written, CD-R discs closely mimic the optical characteristics of prerecorded (pressed) CDs. As a result, they can be read on almost any computer CD-ROM drive, CD-R or CD-R/RW recorder or MultiRead-compliant DVD-ROM drive or recorder.
Is CD rot real?
Disc rot is the tendency of CD or DVD or other optical discs to become unreadable because of physical or chemical deterioration.
How long will a CD last?
The relative stability of optical disc formats
|Optical disc formats||Average longevity|
|CD-R (phthalocyanine dye, gold metal layer)||>100 years|
|CD-R (phthalocyanine dye, silver alloy metal layer)||50 to 100 years|
|DVD-R (gold metal layer)||50 to 100 years|
|CD (read-only, such as an audio CD)||50 to 100 years|
How many times can a CD be played?
RW discs: RW discs, unlike the other types, can “wear-out.” CD-RW and DVD-RW discs should last for about 1,000 rewrites, and DVD-RAM discs, 100,000 times, before the rewriting capability is lost. The reading functionality of the disc should continue for a limited number of read times after each writing.
