Question on mounting dvd-rw drives.

Hello there. I have a query about mounting. If ever you will insert a media on the drive, does it perform auto mounting? Because every time I insert my media on the drive and check if it is mounted by the mount command, it is not there on the list of mounted devices. But the media is detected. Could this be possible?

In addition, do I need to mount the device whenever I burn a DVD or CD?

Automounting depends upon your Linux distribution, and how it's setup by them. If it is not automounted, you can mount it by using the mount command. One example:
root@wired_silas:~# mount -t iso9660 /dev/hda /mnt/dvd/
mount: block device /dev/hda is write-protected, mounting read-only

root@wired_silas:~# mount
/dev/mapper/cryptroot on / type jfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/sda6 on /boot type jfs (rw)
/dev/mapper/crypthome on /home type jfs (rw)
/dev/sda1 on /WinXP type ntfs (ro)
/dev/sda2 on /Storage type vfat (rw)
/dev/sda4 on /Ghost type vfat (rw) on /serverhome type nfs (rw,rsize=8192,wsize=8192,hard,intr,addr= on /server1 type nfs (rw,rsize=8192,wsize=8192,hard,intr,addr= on /server2 type nfs (rw,rsize=8192,wsize=8192,hard,intr,addr=
/dev/hda on /mnt/dvd type iso9660 (ro)
You do not mount audio CDs, just data.

You do not mount a DVD/CD to burn it. Here are some helpful command line options:
To erase a CD-RW:
cdrecord -v dev=/dev/hd* blank=fast

To blank a DVD+RW:
su -c "growisofs -Z /dev/dvd=/dev/zero"
dvd+rw-format -force -lead-out /dev/dvd

To burn an image of a CD to the hard drive:
dd if=/dev/hd* of=namethecd.iso

To make a CD from the iso image:
cdrecord -v -eject driveropts=burnfree dev=/dev/hd* /path/to/file.iso

To save a copy of a data CD-ROM:
gzip < /dev/cdrom > cdrom.iso.gz

To create a CD-ROM image (iso file) from a directory:
mkisofs -r dir | gzip > cdrom.iso.gz

To mount a CD-ROM image (iso file) for viewing/editing:
mount -oloop cdrom.iso /mnt/dir

To burn an iso to DVD:
growisofs -dvd-compat -Z /dev/hd*=image.iso

To copy a VCD from one CD-RW/DVD+/-RW drive to another:
cdrdao copy --device /dev/hd8 --source-device /dev/hd*

Copying a VCD with cdrdao:
cdrdao read-cd --device /dev/cdrom toctoc
cdrdao write --device /dev/cdrom1 toctoc
rm toctoc
eject /dev/cdrom
eject /dev/cdrom1
Or you can use some GUI apps such as K3B.
