How to disable the scsi cdrom driver/bus permanently?

[David Taveras]

Hello,


Is there anyway to disable the cdrom driver permanently so the users
cannot read/write any cds?

Below is my lsmod but i cannot see it... there must be a way??
Apparently according to lshw it is a SCSI.. but i need to disable the
cdrom ONLY otherwise i would be disabling the hard disk which is scsi.
