Why is compact disc spelled with a c and not a k?

The term "compact disc" is spelled with a "c" instead of a "k" primarily due to its origins in the English language and the influence of standard spelling conventions. The Word "disc" is derived from the Latin "discus," which uses a "c." Additionally, the spelling "disc" is commonly used in British English, while "disk" is more prevalent in American English, particularly for magnetic storage media. The use of "compact disc" aligns with these linguistic norms and historical conventions.
