The most dense storage methods possible, such as
modern
hard drives, can be increased even further by, say,
writing
on the platters with a pen that won't disturb the
magnetic
storage medium. By using different colors of pens we
can
increase this even more. Now if we take our pen marked
hard drive platters and make them wavy (modify the
read
head so it can read a wavy surface) we can encode
information into the 3-d shape of the platter. We can
also
change the physical density of the storage medium by
using different materials for the substrate.
different
chemicals in the ink we wrote with, spinning the
magnetic
encoding particles....
I propose that possible
density of
information storage is actually only limited by the time
required to read and write information not by space.

Pictures. Use pictures. Each is worth 1000 words, or in 60-bit terminology, 60,000 bits. Put them together in some kind of pictorial linguistic compression, like Egyptian hieroglyphics... |

You're all overlooking the obvious here - much more data can
be stored on a disc. |
|
| |
Suppose we can place the disc anywhere on the surface of
the earth, to within (say) 10um. This means that, simpy by
choosing the location of the disc, we can encode more data.
There is also altitude (say, up to a working maximim of 1km,
again with 2um resolution). Also angular orientation. |
|
| |
[Max] The surface area of the Earth is 5.1×10^8 km^2, so if our resolution ia 10um, that gives us 5.1×10^24 points, roughly equal to 2^82. So we'd be able to store 82 bits, or about 10 alphanumeric characters - e.g. the word "intestines" or "vacillates". I'd suggest a Post-It note stuck to the disk would be more cost-effective. |
|
| |
Ah, but then there's altitude - a few more bits. And
orientation, another few. |
|
| |
If my calculations are correct (which they invariably are from
time to time), I believe you will find that this gives sufficient
capacity to encode the message "See other disc." |
|
| |
Have you examined how the weight/volume of the
ink compares to an additional magnetic byte? |
|
| |
And the extra thickness?
There is, at some point, a quantum of information
storage, what exactly that is we don't know,
although it probably falls somewhere in the
molecular storage range, which we've got some time
before we hit, admittedly. |

I think there is a chance to use a very good compression system here: a large dictionary with the drive sitting on the appropriate word. |
