Next-gen hard drives include laser

Seagate hits 1 terabit per square inch, 60TB hard drives on their way

Quote:
To achieve such a huge leap in density, Seagate had to use a technology called heat-assisted magnetic recording (HAMR)...

...the head seeks as normal, but whenever it wants to write data, the laser turns on.
mind*boggled

Quote:
Just so you understand how small the magnetic bits are in a HAMR drive, one terabit per square inch equates to two million bits per linear inch; in other words, each site is just 12.7 nanometers long — or about a dozen atoms.
mind*severely*boggled

What would you use a 60TB drive to do?... I suppose I could hook a camera up to my body and record every single frame of every single day. That could end some arguments.

Shit's getting weird. 12 atoms worth to make a 0 or 1. That has to be a limit right there.

I don't know; there's probably analog states you could put a single atom into, such that you could get multiple bits into an atom with the proper manipulation and measurement.

And when the heisenberg compensator is invented, all bets are off!

That is pretty damn amazing.

I recently saw an old (probably 1970s, maybe early 80s) hard drive, I think it was 5 megabytes, and cost $2495 .... plus the $495 for the connection kit!

Wow, just WOW! Somewhere in my boxes of stuff I have an old seagate harddrive, it's like a 40MB drive that has it's own BIOS. HA! Things have sure come a long way since I was a kid.

We were saying that when massive 10 Mbyte drives were available. That industry is simply doing what any productive industry must do.

Back in the early days, we even had one drive that moves its heads with oil. The service call included a pint of motor oil and rags.

But it also means that programmers will get more and more sloppy,
and code will just keep expanding to fill the voids,
and never be revised, updated, cleaned up, etc.

Look at MS Word... I'm using Mac v11.3 from 2004, and it is 19.5 MB
It's really no better than MS Word 5.1 which was only 8K on a floppy.
... just a big, fat lummox sitting on my drive, taking longer to load,
and always trying to tell me what it thinks I want to do.

A laser with Sharks on it's head!


so, how much can a human brain hold? have we ...or will we soon, eclipse the storage potential of our electro chemical grey matter?

for some reason, I was thinking the brain holds a TB. ... but I might be making that up.

But our memory is superior, because when we don't remember stuff perfectly, we fill in the blanks with fabricated stuff. So the amount of stuff we can "remember" is basically limitless.

Research suggests we do not remember as people did some many thousand years ago. Back then, people memorized whole stories and songs. After all, how did the bible record a story some 80 years after Christ died?

Today, we don't memorized whole stories or events. We memorize keywords and significant phrases. The process of memorization is more based in that different process. Then humans fill in the gaps by consulting radical and new technologies that have only recently been developed. Including books, files, and computers.

The common man once was not even allowed to read the bible. These new technologies have changed the brain; how man remembers.

Also suggested was that due to so much excessive sugar, humans do not have the memory capacity once found in humans a thousand years ago. Excessive sugar has been proposed as a source of diminish memory capacity. No problem. Disk drives are on a sugar free diet of pure electricity.

Try the Moonwalking with Einstein. All about memory, how it works etc. the mechanisms developed by early man go memorize everything are still in place. It's all about our spatial memory.

I recently saw a program on Nat Geo (I think lol) about memory and what our brain CHOOSES to remember. It virtually discards almost 100% of what we take in.
