Stop using the term CD as this will only confuse. These are DVD and the meaning is quite different.
That’s a suggestion not an order if it seemed like that
You treat these printable DVDs as you would any other DVD, it’s just that with the right type of printer you can print of the top surface rather than hand write.
Not sure just what you mean by this “And is this RW CD???”. But I’ll try and answer. The RW logo on DVDs does not mean that they are ReWritable & confuses loads of people.
Rewritables are available but are designated DVD-RW or DVD+RW & these you have are not this type & can only be written once.
When burning DVDs is generally best to burn at the rated speed (16x in this case) or maybe just one step down (12x for these). The quality of the burn is not improved by much slower writing. Hopefully your burner & system are capable of 16x burning.
For a definition of Advanced AZO+ ,read it on the Verbatim website as its a branding that is specific to Verbatim (I believe).
