English adopted both spellings. For centuries, writers used them interchangeably. You can even find both spellings in old medical and astronomy texts describing a round and flat object. Over time, industries began to prefer one spelling over the other.
The music world kept disc, especially with phonograph records and later compact disc (CD). Technology adopted disk for magnetic storage media and computer-related lingo. This natural split created the modern disc spelling vs disk spelling rule we follow today.
