Are you confused about whether to use disc vs. disk in your writing? You’re not alone! These two words are often used interchangeably, but they do have some subtle differences in meaning and usage. In this article, we’ll explore the differences between “disk” and “disc” in English grammar and vocabulary, and help you determine which one to use in different contexts.
Disc vs. Disk: What’s the Difference?
Disc vs. Disk: Origins and Etymology
Disk and disc are two spellings of the same word, but is there a difference between the two? Let’s take a closer look at the origins and etymology of these words to find out.
Latin Word Discus
The Latin word “discus” means “quoit, discus, disk”. It is derived from the Greek word “diskos”, which means “disk, quoit, platter”. In Latin, “discus” was used to refer to a flat, round object that was thrown in athletic competitions. Over time, the word came to be used more generally to refer to any flat, round object, such as a plate or a disk.
Greek Word Diskos
The Greek word “diskos” is the origin of the word “disc”. It was used to refer to a flat, circular object that was thrown in athletic competitions, much like the Latin word “discus”. The word eventually came to be used more generally to refer to any flat, circular object.
French Word Disco
The French word “disque” is the origin of the word “disk”. The word originally referred to a phonograph record, but it has since come to be used more generally to refer to any flat, circular object.
Alternate Spellings
The spellings “disk” and “disc” are both correct, but they are used in different contexts. In American English, “disk” is the preferred spelling, while in British English, “disc” is more commonly used. However, there are some instances where one spelling is applied more often than the other. For example, “disc” is more commonly used in the context of optical discs, such as CDs and DVDs, while “disk” is more commonly used in the context of computer hard disks.
Personal Preferences and Regional Differences
When it comes to using the terms “disk” and “disc,” personal preference and regional differences play a significant role. Both spellings are correct, but their usage can vary depending on the context and the speaker’s location.
In American English, “disk” is the preferred spelling, while in British English, “disc” is more commonly used. However, this is not a hard and fast rule, and there are exceptions to this regional preference.
Personal preference also plays a role in the choice between “disk” and “disc.” Some people may simply prefer one spelling over the other, regardless of their location or the context in which the word is used.
For example, a person who works in the computer industry may prefer to use “disk” for all disk-related terms, even if they are British. On the other hand, a person who is a music enthusiast may prefer to use “disc” for all music-related terms, even if they are American.
It is essential to note that while these preferences exist, they do not necessarily indicate a lack of knowledge or education. Both spellings are correct, and it is up to the speaker or writer to choose the one that they prefer or that is most appropriate for the context.
Here are some examples to illustrate the differences:
- American English: “The computer’s hard disk is almost full.”
- British English: “The computer’s hard disc is almost full.”
- Personal preference: “I prefer to use ‘disc’ instead of ‘disk’ when referring to CDs.”
- Regional difference: “In the UK, it is common to refer to a driver’s license as a ‘driving licence’ with a ‘licence disc’ displayed on the windshield.”

Disc vs. Disk in Astronomy
A disk is typically used to describe a flat, circular object that has a thickness to it. For example, the rings of Saturn are often referred to as a disk because they are relatively thin compared to the planet itself. The term “disk” can also be used to describe the shape of a galaxy, such as the Milky Way.
On the other hand, a disc is used to describe a flat, circular object that is thin and has no thickness. For example, the sun can be described as a disc because it appears as a flat circle in the sky. The term “disc” can also be used to describe the shape of a celestial object, such as a planet or a moon.
It’s important to note that these terms are not always used consistently in astronomy. Some sources may use “disk” to describe a celestial object that others would describe as a “disc,” and vice versa. Additionally, some sources may use these terms interchangeably without any distinction between them.
Here are a few examples to illustrate the differences:
- The rings of Saturn are a disk-shaped feature around the planet.
- The sun appears as a disc in the sky.
- The Milky Way is a disk-shaped galaxy.
In conclusion, while there are subtle differences in the usage of “disk” and “disc” in astronomy, they are often used interchangeably. It’s important to consider the context in which these terms are being used to determine their meaning.
