I want to know the CD Driver whether can read CD disc or DVD disc.
Though I have used DRDevice, I can not get information about the
CD Driver can read CD or DVD.
As I understand it DRDevice is only good for getting the optical
drives writing capabilities. To find out read information about an
optical drive before a disc is inserted you could try parsing the
output from the terminal command "system_profiler". See the relevant
system_profiler man page for more information.
Alternatively there is a low level C based Unix library "ioctl". This
may give you what you want. There is some example code on your hard
disk to get you started with this: /Developer/Examples/DiscRecording/C/
drioctl/
