Which is why you also shouldn’t write onto CDs with permanent markers.
DVDs on the other hand have a relatively thick plastic layer on top, offering fairly good protection. Image source

Can’t CDs also have two layers of plastic? I thought it was just cheap CDs that printed the label directly onto the data layer.
