Thanks for your answer.

I installed the wmi module and use the following code to generate 
Win32_CDROMDrive's Capabilities:

   >>> import wmi
   >>> c = wmi.WMI()
   >>> cds = c.CDROMDrive()
   >>> cds
   [<wmi._wmi_object instance at 0x00EDC508>]
   >>> cds[0].Capabilities
   (3, 7)

I have only one CD-RW drive with an empty CD-R disc inserted.  It is 
expected that the capability "4" (write access) should be in 
cds[0].Capabilities.  However it isn't there.
