Terrabit Per-Square-Inch Hard Drive

Posted by timothy on from the density-is-not-a-bad-thing dept.

BitGuy writes: "Physics News Update reports that current GMR (giant magnetoresistance) harddisk technology will not achieve terrabit-per-square-inch densities. Experiments with EMR (extra-ordinary magnetoresistive), which exceeds 100Gb/in^2 have been successful in the lab. There is even a diagram of the read head if you're interested."

    What a bizarre way to report the story. The news is not that terrabit densities have been achieved; rather, that GMR will not be the technique that will get us there. Hardly news at all.

  2. it's TERA- by Anonymous Coward · · Score: 1, Informative

    Tera is the SI prefix for trillion (10^12), not terra, which is Latin for earth.
