What is the Difference Between CDR and CD ROM?

The main difference between CDR and CD-ROM lies in their usability and data storage capabilities. Here are the key differences:

• CDR (Compact Disc Recordable): This is a blank disc that you can use to store data, such as audio, videos, or other types of media formats, by burning or writing the data onto the disc. CDR discs have a greenish/silver hue on the bottom. The data in CDR is stored by burning and/or writing, and it is considered a WORM (Write Once Read Many).
• CD-ROM (Compact Disc Read-Only Memory): This type of disc contains pre-pressed data, usually software or games, that can only be read and not written or stored upon. CD-ROM discs typically have a silver bottom. The data stored in the CD-ROM is stored by pressing.

In summary:

• Data can be written or burned into a CDR.
• CD-ROM is only for reading data and never for storing data.
• The data in CDR is stored by burning and/or writing, whereas the data in a CD-ROM is stored by pressing.

Comparative Table: CDR vs CD ROM

Here is a table comparing the differences between CD-R and CD-ROM:

In summary, CD-R is a type of disc used to store or burn audio, movies, or other material, while CD-ROM is a pre-pressed optical compact disc that contains pre-stored data. CD-R allows users to write data onto the disc, whereas CD-ROM is read-only, meaning the data cannot be altered.
