  • Put it in a CD drive and also see if it functions.

  • Usually they claim on the front of the media

  • I assume there are some markings near where the pin goes which might show it

You can not simply via checkup. Both are 120mm in size and also 1.2 mm thick.

If the supplier hasn't created something detailed on the tag (or on the message by the pin opening) after that you can not discriminate simply via monitoring.

If you have accessibility to a high power microscopic lense you can check out the surface area of the disk as the pit dimensions vary for CDs and also DVDs, you'll locate the pit are 0.74 µm for DVD versus 1.6 µm for CDs.

[The majority of DVD creating software program (like CD heater XP or Nero) will certainly inform you what sort of disk remains in the drive. ]

Sometimes DVD media will certainly have a various shade on the writable side. I've seen some that are blue and also some that have a purple tone. If that holds true, it is possibly a DVD. Yet Simon Stevens is right, you usually can not inform via checkup unless the supplier has actually tinted the disk.
