I cant eject cd wen my application once read from cd.Please Help

Hai all
 I newbie in cocoa.I am now with font manager devolopment. The proj
want to read font from CD.I can read data from cd and use the data.but
I cant to eject cd wen application loaded and readed once from CD.After
reading  i read font from system font. then also i cant eject cd .CD
can eject only after closing application .
Wen try to close then a dialog box appears with "one application is
using cd close application and try".
I tried by removing all datas from arrays used,but then also cant
eject.

The pgm. work with font is below .please check that i hav missed any
code to be added with this to remove control over directory that is
currently using.

I have no idea about FSRef,FSpath,ATSFontRef.If anyone of the above
want to release or deallocate.I think one of them are continuing
control of cd wen once read data from cd.Wat i will do to eject cd wen
app. is running.Ejecting cd is for changing the cd and try it with
another cd.

Excuse my english .Please help
