Definition
Noun: A CD-R is a type of compact disc on which data can be recorded by a user only one time. After this recording process, the data becomes permanent and the disc functions as a read-only memory (ROM) device, meaning the information cannot be erased or rewritten.
Usage
The term CD-R is used to specify a recordable, write-once optical disc format. It distinguishes this type of disc from a standard pre-recorded CD (CD-ROM) or a rewritable disc (CD-RW).
Examples
- I burned the presentation files onto a CD-R for archival purposes.
- Make sure you use a CD-R and not a CD-RW if you want to create a permanent music disc for your car.
- The software allows you to create a bootable CD-R.
Advanced Usage
- As an adjective: The term can function attributively to describe other nouns related to the technology.
- Example: The computer has a CD-R drive capable of recording discs.
- In technical contexts: Often discussed in terms of its dye-layer technology and compatibility with various recording speeds (e.g., 52x CD-R).

Notes
CD-R is an initialism for Compact Disc-Recordable. It is a standard digital storage medium, largely superseded by USB flash drives and cloud storage for most data transfer needs, but still used in specific applications like audio mastering, legal archiving, or with older systems.
