How to avoid recording mark

Does anyone know How do I burn an audio CDR so that the entire disk is burnt, thus avoiding those ‘recording mark’ difference in colors, so as to appear as a pressed cd?
Thanks for any answers.

Add silence to the end of the .wav file. Or a new track of all silence. The only problem is that your player will play the silent track instead of just ending. But I’m wondering, why is that important? Regards, gamma1
