I've wrote little script for more convenience
and I add a shortcut to this
all files as .zip attachment to this post

eject program go to /usr/bin/
eject.desktop must be placed in /usr/share/applications/hildon/
eject.png must be placed in /opt/usr/share/icons/hicolor/64x64/apps/
eject.sh must be in /home/user/
eject.sudoers in /etc/sudoers.d/

after copy eject.sudoers file a command must be runed for update sudoers
as root run
create a folder /media/cdrom
edit the desktop for adding eject icon ( optional )
make eject and eject.sh runnable
and reboot for update seceen's icons

BONUS first run the script will mount the cdrom

hope not forget anything ...
