# pw group add cd
# cat >> /etc/devfs.rules 
[devfsrules_common=7]
add path 'acd*'  mode 660 group cd
add path 'cd*'   mode 660 group cd
add path 'pass*' mode 660 group cd
add path 'xpt*'  mode 660 group cd
^D
# echo 'devfs_system_ruleset="devfsrules_common"' >> /etc/rc.conf
# /etc/rc.d/devfs restart
#

then put all required users to group cd, or just change 660 to any
acceptable to you permission bits (say 664)

be care, access to xpt* can compromise any SCSI device on related CAM
bus, frankly speaking pass* and xpt* is required for writing CD/DVD with
cdrecord, if you have ATAPI CDROM and do not pan use atapicam you need
only acd* entry.

(really not sure about /etc/rc.d/devfs restart - never tried it, but
should work)

also, this solution will work for plugable cd crives
(pccard/firewire/usb/scsi/whatever...)

also 'man 8 devfs' - is not bad place to start

PS: 
to all, we need better documentation for /etc/devfs.ruleset file.
