result=`isoinfo -i /dev/cdrom -d`
retcode=$?
$retcode will be 123 for an empty drive, 1 for a blank cdr, 0 for a cdr with
an iso file system on it.
You can pipe $result into grep to search for specific strings to get more
information.
You might need to use result=`cdrecord dev=0,0,0 -msinfo` when you get a
$retcode of 0. If the cdr is fixated $result will be an empty string,
otherwise you will get a pair of numbers separated with a comma.
The 0,0,0 and /dev/cdrom need to be values that apply to your system.
