'Disc' is a word from English and is pronounced that way too. It is the short form of 'Compact Disc' (CD) or refers to a flying disc.
Er hat seine ganze Musiksammlung noch auf Discs.
He still has his entire music collection on discs.
The context tells you whether a CD or a flying disc is meant. Verbs like 'hören' (to listen) or 'einlegen' (to insert) point to a CD, while verbs like 'werfen' (to throw) or 'fangen' (to catch) refer to the flying disc.
Er legte die Disc in den Player ein.
He put the disc into the player.
In the meaning 'Wurfscheibe' (flying disc), 'Disc' is often used in connection with sports such as 'Discgolf' (disc golf) or 'Ultimate Frisbee'. Typical verbs are 'werfen' (to throw) and 'fangen' (to catch).
Beim Discgolf muss man die Disc in einen Korb werfen.
In disc golf, you have to throw the disc into a basket.
club / disk
'die Disc' and 'die Disk' look almost the same and sound similar, but they do not mean the same thing. 'Disc' is used mainly for a CD or for a flying disc in sports. 'Disk' can colloquially mean a club, or, in an older usage, a floppy disk. The risk of confusion is especially high with technology and leisure activities, because both words are short and can be connected with data storage media or entertainment. The context is important: for music on a storage medium, 'Disc' fits; for dancing in a venue, 'Disk' is more likely.
