I tried to explain this in that post. There has to be some threshold in
which "too likely" becomes pesiq reishei. He held that the water 
fountain crossed that line but the front door didn't.

The kesav isn't on the disk or tape, it's on the screen when one of the
two is shown. The tape's recording is invisible, and the disk is just
one rainbow of sub-visible dots vs another. Displaying a picture from
them would be the actual kesivah. And that's not permanent.

For this reason, RDLifshitz said in shiur that a sheim appearing on a
computer monitor is like Chazal's case of one written in the sand at
the beach, below the tide line. The bits on a disk don't matter. It will
inevitably be erased, so it lacks qedushah now.

By that definition of writing, there is no kesivah of a permanent record
in our case either.

Tir'u baTov!
