I have personally burned several Mac HFS CD-Rs
and one AmigaDOS CD-R.
I burn Mac HFS CDs all the time.
The secret is that burners have common "image" file formats, so as long as
the data gets into the image file correctly, it burns correctly.
BTW wow do I like my CDRW, its a Sanyo BP1500 II drive in a QPS! bundle
with Nero 5.5, which means it burns CDs at 24x and the burnproof technology
means no bad burns.
