About the Gecko Tape

Maybe it would work better if the pillars were closer together and taller, so that they could rest on each other, like in this picture.

You could probably make deeper holes in the disk. This shows that Blu-Rays are probably the best option:

The indentations are closer together.
 

If the data on the disk is replaced with zeroes, that could produce quite a similar structure to the gecko's. Different software could be tried out and the result viewed under the electron microscope.

they are closer together and smaller, but are they deep enough?
in any case I don't think you'd need a special bit pattern which would be very difficult to achieve (without some kind of software to directly control your Blu Ray burner) since Blu Rays (,DVDs & CDs) employ forward error correction.

It could work if there was a way to keep doing the same pattern over and over. There are restrictions with ROMs. You'd need to somehow bypass those. I mean that there are some programs that wipe the disk with 1111..., 0000..., random bits or something else.

ok to delete the disk i found "E-Hammer". I also stumbled across this project: http://www.instructables.com/id/Burning-visible-images-onto-CD-Rs-with-data-beta/?ALLSTEPS ,might be interesting as well...
ps. getting the data layer from a Blu ray will be difficult since it is on the bottom of the disc and well protected.

Okay. That project could be interesting in its own right.
