So... what's the chance of doing this with a solid-state laser?
Say 9 of them? The idea of high-speed papertape (sic) thrills me.
I know I'm sick, but I don't want to stop.
Use a laser whose output the tape isn't
transparent to; a "1" is a
heat-distorted/discolored spot. A smaller spot for the "sprocket"
hole/index.
Yes, reflectance rather than mechano-optical hole-or-not
would be much faster. Like a CD, but flexible, on a spool.
Much great surface area than a 34 mm radius band on a 120 mm disc.
