Disc VS Disk: What Are the Differences Between Disk and Disc?

Disc VS Disk Definition
Although disk and disc are pronounced the same, technically speaking, they have distinct differences.

A disc refers to optical media, including CD, CD-ROM, DVD-ROM, DVD-RAM, or DVD-Video disc. A disc is usually used to save multimedia files such as music and videos.

A disk (also known as “hard drive”) refers to magnetic media, such as a floppy disk, hard disk drive (HDD), solid state drive (SSD), external hard drive, etc., which are usually sealed inside a metal or plastic casing and can be used to save all kinds of files.

- Read-only disc: This refers to Compact Disc Read-Only Memory (CD-ROM) which is forbidden to write files.
- Write-once-read-many disc: such kind of disc allows you to write files to the disc once, such as a CD-R or DVD-R, unless you do a multisession burn;
- Rewritable disc: these discs can be erased and rewritten over many times, such as CD-RW, DVD-RW, and DVD-RAM discs.
