Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 6, 2023
CD-R (Compact Disc Recordable) allows for data to be written once and read many times, whereas CD-ROM (Compact Disc Read-Only Memory) is pre-pressed with data and can only be read.

Key Differences
The CD-R is a type of optical disc that users can write data to, but only once. On the other hand, the CD-ROM is a disc that comes with pre-stored data, which users cannot overwrite. Both CD-R and CD-ROM utilize the same size and appearance, but they serve different purposes when it comes to data management and distribution.
CD-R stands for Compact Disc Recordable. As the name suggests, it gives the user the ability to record or burn their own data onto the disc. CD-ROM, which stands for Compact Disc Read-Only Memory, doesn't provide this flexibility, as its content is fixed at the time of manufacture.
When someone burns information onto a CD-R, the data becomes permanent. The CD-R doesn't allow for erasing or rewriting over existing data. Conversely, the CD-ROM is strictly a medium for reading. It never allows for any kind of data writing or modification.
For users looking to distribute or store their own data, the CD-R offers a useful tool. For those seeking to acquire software, music, or any pre-packaged data, the CD-ROM serves as the go-to format. Both CD-R and CD-ROM have played pivotal roles in data storage and distribution, each complementing the other in various contexts.
