My fstab has this (modified by me to provide a permanent mount point):

   /dev/hdc1  /media/cdrecorder udf,iso9660  users,defaults  0 0

Note that it can mount either udf (CDRW) or iso9660 (CDROM). Other
options are also available (see man mount, or man fstab for details).
The udf filesystem is rewritable, and can be added to until the disk is
full.  The iso9660 OTOH is read only.  The system will not mount a CDROM
as writable, even it you specify it as such in fstab (The disk after all
is physically not writable).

If you manually create the mount point, and add the line to fstab, then
the mount point will remain and will be used each time a disk is
inserted.  If you do not do that, then HAL/udev will automatically
create/remove the mount points as disks are inserted/unmounted.
