Locate the desktop on Mac Classic?

[Signe Marie Sanne]

Hello,
I run an application from a CD-ROM. The students can use a note book, and 
their file shall end up either on the desktop or in a folder on the desktop 
on Mac.

On my own Mac the harddisk is named "/signes/" whereas the first component 
may vary on other people's computers:"Harddisk", "Mac HD" etc.
How can I identify its name from the CD-ROM in order to write the notes' 
file to the harddisk?

Thanks in advance.
