For example, a compact disc stores digital information, while a disc brake uses a circular component to help stop a vehicle. You can also use disc when you talk about disc golf or a spinal disc.

British English commonly favors disc in many general contexts. American English also uses disc in several established expressions, so you should not treat the word as exclusively British.
