Tape device /dev/st0 question

Hello All, My tape drive is accessible via. /dev/st0 and I have a symlink /dev/tape which points to it. This all works fine as root I would like to create a group which allows access to the tape drive, that way if I need a non-root user to use the tape drive I can simply add that user to the group. Is this possible? How do I allow that group to access the tape drive? All suggestions are welcome... Many thanks Ahbaid
