Get Perpendicular!

[hamsterTK 93]

Hitachi discovered a way to vastly increase the amount of data that can be stored on a HD, and made this little cartoon about it.

everyone oughta watch this. its funny, and it also explains how a hard drive stores data. so its informative as well.

Like i said earlier, its cool, its done like schoolhouse rock

Ok, honestly, who in their right mind would need 30,000 songs in the palm of their hand?!

My itty bitty 1GB player is more than enough for me.  But I don't want music constantly pounding through my head 24/7 like the rest of my college colleagues.

I am definately going to invest in the hearing aid industry when I'm making the big bucks.

i was thinking the same thing lol....

of course this technology will be used in much much more than dinky HD's for MP3 players. If a teensy microdrive with perpendicular arranged bits can hold 30,000 songs worth of data, imagine how much a full sized HD could hold of any sort of data

Actually, they've had this technology out for a while now. Most of the public is just now learning about it, but when it becomes more widespread, it will REALLY be useful.

One must ask the question though.

Just becuase they are upright how does that prevent the Superpara magentic effect?

The bits are packed even tighter together would not that make the effect worse?

When Hitachi bought the HD sector of IBM, they aquired the antidote for that.  Problem solved.

Guys, guys, this is not about storing songs.  Think about having a server with 10 to 100x the current density for the database in the same space.  Think about how small a HD could be and still store, say, 1024GB (1 Terabyte, abbreviated TB which does not stand for two beauts).

13,000 songs? 3,000 is enough.

They still have just as much space between them, so no. You can fit more dominoes on a table if you stand them up than if you lie them down, even if you leave an inch between them in each case.

What I find troublesome Is that this is considered "the wave of the future". It's magnetic storage, like what Floppy Disks used. The problem still remains that a reasonably strong magnetic field will wipe your drive clean. Anything with a magnet in it generates a magnetic field. Anything with a magnet like, say, stereo speakers? Optical storage (like CDs and DVDs use) doesn't have that problem!

As for who in their right mind would want space for 30,000 songs, well... more people than you might think. Lots of people have hundreds of CDs and would love to be able to fit them all on there. I have over 6,000 songs myself. And that number will only get larger as time goes by.

It's not about having tons more songs on there than you can possibly listen to in one sitting, it's about having selection, so you can choose to listen to whatever whenever as opposed to having to choose from the collection you were able to fit on there.

To show what this technology can do, (I believe) Seagate is comming out with a 750gb hard drive soon, and PC world believes that 2TB drives could be on the way soon.

Actually, Hitachi will be packing the bits in tighter (the orientation allows them to pack them closer before they suffer the same effect that the same bits would suffer if packed horizontally.

Thats what i meant, eventually they will start packing them closer/making them smaller ect to increase the storage sizes so they will  have this problem again, proabaly within a  few years.

I wonder if  RAM is horizontal or Perpendicular bits? when its stored.

[hym 358]

Yeah, the problem will surface again, but like VT said, they acquired the cure from IBM so it likely won't be happening any time soon.

[Voar Tok 4]

I'm not entirely sure how this would work in the real world, but for theoretical purposes, let's just assume that one of these bits takes up only half of the space in a vertical position as it does in a horizontal position.  By flipping them up, that would allow you to make the platters only half of the size they were originally.  Everything (well, roughly everything) would be only half the size it currently is now.  So, that would make it easier to pack the same quantity of data in an even smaller space.  Pretty soon, HDs would get to be so small that you could swallow them by accident  OK, that's going to be a few years off, but you get the drift.

A couple of things were mentioned in this thread:

Optical Storage

Essentially, write once read many (WORM) technology.  Lasers actually burn (destroy) the recoring media.  RW CD and DVD media is still magnetic, just laser guided for close packing.

Random Access Memory (main computer memory)

The chips these days are not static.  They are electronic delay lines and are continually refreshed.  They circulate until they are read out (then renewed in the read(/write) cycle.  If they were permanent (flash or writeable semiconductor) you wouldn't lose them on power off.  The trade-off in this techology is speed.
