The prop holotape is just a simple LED. The Functional Holotape won't actually hold any data. Instead it will work like a simple IR remote control. Sending out one of twelve unique ID numbers. The Pip-Boy will receive one of these numbers and do a pre-programmed action. (Audio file, app, or game)

Otherwise, no I don't plan on making a separate recorder prop, as there isn't any in Fallout 4.
