However, this forecast never came true, just as any other long-term forecast. The problem was connected with continuous reduction of the magnetic bit size. The smaller got the bit, the higher was the probability that its magnetic polarity may change spontaneously due to the influence imposed by the magnetic power from the neighboring bits. Since with the current data density one domain contains just a few dozens of bits, then the oscillation of just one single bit may result into an avalanche-like phenomenon. Of course, in this case we should really worry about the data security.. Head over to Xbit to learn more about this HDD..
