Identify type of CD?

I have a disk with almost no labeling. I can tell by looking that it's a CD and not a DVD. I can tell by looking closer which side is which (mfg. part/batch number) and that it is blank (writing makes a band of different appearance). I can also have my MacBook Pro tell me all those things by putting it in the optical drive. But is there a non-invasive way for MacOS to tell me whether it's CD-RW or just CD-R? (ReWritable or Recordable.) drutil can only tell me the drive's capabilities, unless I try an erase, which may make a CD-R unusable. Web search for the part number(s) found nothing. If I try to re-write, I’ll know. But at that point, it will no longer be usable, and I’ll have to go buy another. My nephew stopped by and found it by Properties in Windows, but it would be nice to know a MacOS or Darwin method.
