My worry would be that the coercivity is almost certain to be wrong. I 
can rememeber when fooling around with reel-to-reel video recorders that 
if you used 'high band' tape on a 'low band' machine you got almost no 
signal off the tape.

I have also been told that 1/2" computer tape makes lousy video tape (by 
somebody who tried it in an N1500), I suspect the reverse is also true.

And anyway, how much longer do you expect to find VHS tapes on sale just

As regards slittling the tape, classic camera enthusiasts (another of 
_my_ hobbies) routinely slit film down to make it fit obscure cameras 
(e.g. turn 120 into 127). This is in one respect easier than tape (film 
is thicker and stiffer), in aother respect harder (you have to do it in 
total darkness). Tyipcally, you make up a jig to hold a couple of razor 
blades the right distance apart, and run the film over them -- often 
using a 'junk' camera, like a Box-Brownie (for 120 or 620 input), some 
35mm compact (for 35mm input, to make subminature film), etc. Doubtless a 
similar idea could be made for magnetic tape.
