What's the difference between a "disc" and a "disk?" - https://support.apple.com/HT201697 - optical cf. magnetic.
Get info on your iTunes folder and see how much space it takes up. If it is the culprit then you may need to move the library to an external drive. This isn't at all unusual since people want small computers which have inadequate storage but there's a glut of digital media.
