Two heads better than one for hard disk security

Double the fun...

Japanese boffins have developed a supposedly hack-proof hard disk with two separate heads.

The disk features a read-only head which is connected to the web server with one cable and a read/write head which is connected to the PC with another cable.

The internet can only be accessed via the read-only disk, which the scientists claim makes it impossible for an outsider to get to any sensitive internal company data.

The two-headed disk was invented as far back as 1985 by Naoto Takano, now CEO of Japanese hardware firm Scarabs. His company succeeded in making a prototype last year. The system costs around $900 to build and can run on any operating system.
