Better don't do that. If you are a member of the group disk, you can 
write directly to any disk, ignoring the permissions set by your file 
systems. If you now start a malicious or buggy program it may overwrite 
your harddisks, which is certainly not what you want.

I'm not sure what is wrong on your system, but unless things have 
changed recently, the CD drive should be owned by root with group cdrom. 
Are you sure that sdb1 is the CD? Usually CDs don't have partitions. It 
looks more like a USB stick or memory card.
