Terrabit Per-Square-Inch Hard Drive

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."

    Giant magnetoresistance (GMR) and tunneling magnetoresistance (TMR) hard disk technologies cannot achieve Terrabit per square inch performance. Neither can the "extraordinary" magnetoresistive (EMR) hard disk that is proposed. It is hoped that in the near future "extra-extraordinary" magnetoresistance (EEMR) hard disk technology is developed, and then perhaps "goddamn-extraordinary" magnetoresistance (GDEMR).

    It's kind of scary looking at the thing that in five or ten years we'll be depending on to store our data, and seeing the huge irregularities in its structure. I suppose the stuff inside computers right now is like that too, but it makes you wonder how they get the precision they need, and why those flaws don't make the things break more often than they do.
