[X4U] Data and audio CD question

[Jan Melichar]

I'm finishing off a site which will appear on a CD. The CD will also 
have audio which can be played on a CD player

So far all appear to work but the only way I have managed to do this 
(and thus avoid the problem of a CD player attempting to 'play' the 
data) is by recording the audio and data onto a CD in two parts. The 
downside of this is that one gets two disk images. This may be 
confusing to the user. I know that files can be made invisible but have 
no idea how to do this.

I would be grateful for any advise how to make the 'audio part' 
invisible to both mac and windows users.

I am on a mac.

Thanks

Jan
