Path name to CD drive

[Tiemo Hollmann TB]

Hello,

if I want to get the path to an inserted CD, with name "foo" I can check on
Mac "the drives", if my disk is inserted. But actually the full path is
"/Volumes/foo/myfile"

Not having so much experience on Mac I would like to know, if I can always
set "/Volumes/" as a prefix before my disk name or is the name "Volumes"
customizable on different Macs?

Or is there another straight way to get the path to a known file on a known
CD?

Thanks

Tiemo
