Nickel Sensors Could Raise Hard Disk Capacity
Makarand writes "Tiny filaments of nickel, thinner than a wavelength of visible light, acting as magnetic
sensors may expand the storage capacity of hard disks many times. Although, technologies
exist to increase hard disk capacity, reading data bits reliably from such disks has proven
difficult because as data bits become smaller their magnetic fields are weaker and difficult
to pick up. Nickel filaments are capable of picking up of these weak magnetic fields
using a phenomenon called "ballistic magnetoresistance" which is not completely understood.
As the sensors are only a few atoms wide the electrons travel along a straight line
in the conductor greatly enhancing the binary signal picked up from the data bits.
These sensors could also be used to detect biomolecules in low concentrations."
Ah yes, a sweet first posting.
post ????
People die every day. do you complain like this every time?
get a life not the one news television sells you.
Allah be praised
Then I guess we should all still be talking about this:
Bus Crash Kills 27.
Speaking of priorities...
Fascism should more properly be called corporatism, since it is the merger of state and corporate power.
You people make me sick. It's no time for joking. I hope when America goes after the people responsible for this, they take out a few nerf toy playing, lego building, video game buying faggot little 5-year-old acting geeks as well.
GROW THE FUCK *UP*, PEOPLE. GET A FUCKING LIFE, GEEKS!
Best post ever!
Priorities? You mean a tangent discussion on a drunk driving crash that happened over 10 years ago? I'm sorry, I think we all missed your point; not to mention the fact this has absolutely nothing to do with HDD density and new technology. By your rationale, we shouldn't be discussing anything but this on /.
Oops, accidentally mistook your message for the parent, sorry about that. I still mean what I said, just transfer it to the parent message and the space shuttle explosion.
More than seven people have suffered horrible deaths this week. As a non-American, I won't be attatching any particular significance to such a small number of deaths.
If you cared about people other than astronauts, then you would find that tragedy occurred so often that we would have to mourn constantly and we wouldn't have any time to avert future tragedies.
