Next Wave Of Hard Drive Tech: Perpendicular Recording
angrytuna writes "New serial technologies are set to replace standard SCSI and ATA (Advanced Technology Attachment) interfaces over the next two years, even as hard-disk drive manufacturers prepare for an entirely new form of bit storage. Perpendicular recording will replace longitudinal recording in storage devices, placing bits on end instead of lying them parallel on the disc surface, thus dramatically increasing the possible storage density."
that there is such a crackdown on file-sharing. If they take that away from us, then whats the point of having that much space?
I wonder which side of the debate the hard-disk manufacturers are on?
If my drive bit is standing up, it must be hard. Ergo, hard drive.

If they stand the 1's up, sure you can fit more because they're skinny. But 0's? They're wide...I don't see a significant amount of savings there...
So, does this mean that instead of looking like this:
0
1
All of my bits will instead look like this?:

I suppose you can squeeze a lot more of them together that way, but is that really much of an innovation?
Now, if they had figured out a way to fold the suckers, I'd be impressed.
See, there's a limit to how many bits you can store on a disk. I see. Because the area of the disk is limited I see. But you don't want a limit, you want more space. I want more space. But you can't have more space, because all of the bits are square they're square. and there's only so many square inches of surface. Only so much. Yes. Look at this disk. Radius 3.25" 3.25 It's a circle. It's round. Pie-R-square Pie-R-square So the area's limited. I see.
And the bits, they're almost square, because that's the way the manufacturers' engineers like them. They like squares? Yes. I see. Well, really they're not square, they're almost square. And how's that? Well, they're square sections of a round arc. Not square? But almost square. Almost square. I see.
So what do we do? I don't know. Well, we get a better packing fraction. Better packing fraction? Yes. That's the key. A better packing fraction. I see. And your data is round. Data is round Because the magnetic field is round. I see. And a square doesn't approximate a circle very well, does it? No. What does it better? A circle? Well, yes, but you can't do it with a circle, because circles bump each other. They bump each other? Yes, and they leave empty space between them. And we want a better packing fraction? Yes. So what do we take a cue from? I don't know. I know you don't know, but I'll tell you. We take a cue from the bee. The bee? The honeybee. He uses hexagons. Aaah. Hexagons. Yes, hexagons. They're all the future. The future? The future. The future. Yes, the future. Hexagons. Yes. That's where the money is. You're a nut.
