Traditional hard drives, as you may have guessed, have only one head, like women. However, some genius (and I use that term loosely) decided that hard drives should have two heads. This was back in 1985.
Now, Japanese company ScarabS, whose web page I cannot read because it is not in English (yet does not have a .jp extension like other nice Japanese companies), has finally built a dual-head hard drive. Fortunately, the web page has enough Western characters on it to point us in the direction of a demonstration video that clearly shows two mechanical arms moving back and forth. Fear the technology that is the future.
While this design is supposed to make security concerns less noteworthy, since one head (public Internet viewing, for example) is read-only, and the other allows local admins to change files, I fail to see how it will prevent hackers from hacking in and pretending they are local users. They’re hackers, after all.
On a sidenote, does anyone else find it amusing that the article in question quotes a price of $863 dollars “to build the simplest version of this system”? That’s a pretty frikken precise estimate considering the “simplest version” doesn’t appear to have specs available yet.
