Sony Increases Hard Drive Storage Fivefold
Sony has announced that they’ve increased hard drive storage capacity by five times through developing a new method of writing information that’s viable even for notebooks. Instead of writing via magnetics, the new system resembles current optical technologies, using a hybrid magnet/laser to write information to a disk at densities of 125GB/square inch. As we understand it, most elements of the traditional hard drive stay intact, but your current 320GB hard drive setup would see data storage reaching 1.6TB. Of course, there are no immediate plans for mass production. [itplus via electronista]

Hard Drives of Today will reach the superparamagnetic effect limit according to the premier storage professionals IBM , in the next few years not due to write densities, but the inability to read decreasing S/N EMF fields from the ferromagnetic materials with increasing write bit densities, even if some ingenious method is found like Toshiba 1 Terabit/sqin. concept which has since dropped its density prediction back to 500 gbits/sq.in. is still 2D serial read/write.
Another questionable technology is the HAMR (heat assisted magnetic recording) that NSIC member organizations Seagate Technology , Advanced Research Corporation, MEMS Optical, Inc., Carnegie Mellon University, the University of Arizona and the NSIC itself have started developing.
America’s Seagate “Quinta/Terrastor” (now the reinvented HAMR Technology) is a Magno-Optical Drive Technology similar to Matsushita Electric Industrial Co, Ltd and Canon Inc. Japan , TerraStor , have found that over 10 years of research and ( $125 million Quinta Patents and $ 250 million for Terrastor Patents) plus a ridiculous amount of research funds hasn’t put them any closer using a laser head that doesnt overheat or meltdown permanetly disabling the disk drive. For Seagate’s HAMR to rewrite a limited number and read many times reflected 2D polarized photons of a 50 terabits/sq.in maximum data bit densities and having slow SERIAL READ/WRITE data transfer rates with only a 5 year plus shelf life media should doom this product.
