35TB cartridge poses whole new set of problems IBM Research has devised technology with FujiFilm to create a 35TB capacity tape, but it will take 3 days to write the data at LTO5 speeds. The new hyper-capacity half inch tape technology has been successfully read and written at a 29.5bn bits/sq in areal density, which means a tape capacity of 35TB according to the researchers. This is said to be 44 times the 800MB raw density of LTO4 tape. From a technological point of view the gee whiz factor is impressive. The media is FujiFilm's Nanocubic tape, with an ultra-fine,...

Japan`s Hitachi will introduce its next-generation hard-disk drives attained by a innovative novel approach that packs the tiny magnetic ones and zeros that are the basis for digital storage technology even closer together.The innovative technology known as perpendicular recording because the tiny magnets that represent digits are placed upright, not end to end -- has been anticipated by the magnetic storage industry for more than 20 years. Hitachi announced today that it will produce 230 gbits per square inch meaning it will introduce a 1 inch 20 GB drive. While perpendicular recording has been talked about for years, Seagate, Toshiba...
