You hear this weeping sound? Yeah, it's a MPAA or RIAA representant crying himself to sleep.Their current solution to this problem is recording data perpendicular to the plane of the media. This technology, however, is expected to peak out at about 1 terabit per square inch. In the next decade, Seagate plans to hit the market with twin technologies that could fly far beyond, ultimately offering as much as 50 terabits per square inch. On a standard 3.5-inch drive, that's equivalent to 300 terabits of information, enough to hold the uncompressed contents of the Library of Congress.
