However, he added that enjoying the risks of advanced technologies doesn't mean that the researchers are risk takers. These people take their work very seriously and get a lot of satisfaction in what they do. IBM has had related programs in superconductivity and other germane technologies since the mid '70s. The Defense Advanced Research Projects Agency has helped fund some of those endeavors, and Siemens and Infineon have also had long-term projects. That means the basics for the new project are already set.
Some electrons go through the insulator, it's much like a resistor.
We store information by switching the magnetic field, you read out by reading the resistance. Engineers are unsure whether the magnetic devices will require a totally different packaging technology that blocks stray magnetic fields. There are all forms of magnetic disturbances from the air, the earth and all kinds of technically created magnetic fields. A question we haven't even begun to answer is are they strong enough to cause any impact. Once these concerns are ironed out, the companies will progress to manufacturing and system problems.
