We know that the first 253 episodes of Doctor Who were recorded onto 2 inch Quadruplex videotape and then was used for broadcasts and to make the 16mm and 35mm tele-recording prints before the Quadruplex videotape would be wiped and reused.
We do have some of the Quadruplex videotapes that were used on Doctor Who, though they eithet are wiped clean or have other programs recorded over it. Would it be possible to try to recover the overwritten footage from these tapes? If scanning the tapes with different lights and technology reveals the underlying footage that was on the tapes before being overwritten, that could open up a new avenue of recovery.

No.
The vast majority of master videotapes were simply thrown away after the amount of physical editing done to them made them too short to be of any further use.
And using "different lights" wouldn't make a jot of difference to magnetic videotape.

Is not about a different ink underneath like a palmaset. Rather its about magnetizing and dmagnetizing the metal the same exact way so nothing to filter for..
Any signal if any, that might remain would likely be overpowered by the new signal and noise.
Ideally , if there was no such thing as static , and that we knew there was something valuable underneath. And a copy of what was over it without the static, then it would theoretically researchable. But likely anything left would be so small to pick up, and as the videos would be earliest quality, its falls into the category of picking up shows from space. Too abstract to be practical
Even a tape put through a bulk eraser with nothing over it, any signal would be too low to do anything with.

It is theoretically possible to recover previous images if you have an ultra-clean version of what wiped it and if the original wiping was not perfect.
As a practical matter, not a chance.

I remember when Dr Who Magazine had a feature on the BBC archive. this mentioned that at least one original 2" reel which had been used to record an episode of Dr Who still survives, but was re-used to record an edition of Blue Peter. I presume it was run through an eraser before being reused.

And that seems to be the only instance of this happening which is actually known for certain Doctor Who-wise, isn't it? It's certainly the only example you ever seem to hear about, anyway. |

I presume the other tapes were eventually junked, or were part of the consignment sold to Australia in the 1980s. A lot of the editions of Swap Shop were lost that way. |
