margins, that gives us 93.5 square inches. To have
450GB, we would need 5 million dots per inch !!!!
No scanner today can read that resolution and
no printer today can write that resolution

Here is another way to look at it:
He records on paper, HDD's record on magnetic media ...
it is possible to make a much much smaller magnetic
dipole on a magnetic substrate than it is possible to
make a mark on paper.
and HDDs do not ultimately write just ones and
zeroes to disk either.
Even so, basic physics ... it will always be
possible to make smaller magnetic dipoles than dots of
ink.
how did you do ur calculations ? if u tried to measure how much 0s and 1s it can fit (binary) it will be inaccurate, cz alo eno new encryption, mech binary.. based on forms and shapes... anyways we cant decide yet, its still so vague
