NO, if you like to check for a media change you need to access
the TOC.
      

Thanks, but that's not what I was asking. What I want to know is, if 
I were writing a volume management system, and I wanted to make 
sure it didn't interfere with a write in progress, is there any way 
for it to find out if a disk is being written without disturbing a 
write in progress?
    

NO
  

Joerg is correct, but it's certainly possible to see if a resource is in use, easily in the kernel and usefully in user space. However, I think the desirable thing is for the burning software to protect its resource rather than depend on other software to be curner aware.
