Seagate Technology Inc has broken its own disk drive density record – with a recording density of 23.8 billion bits per square inch – which equates to a storage capacity of nearly 32Gb on a single 3.5 inch disk. In February, Seagate said that it had broken the 16Gb per square inch barrier.
A spokesperson for Seagate said the 23.8Gb per square record was due to a refinement of the previous record-breaking equipment. The density was achieved by using merged read-write giant magneto-resistive (GMR) heads and ultra-smooth alloy media, both designed and manufactured by Seagate. The company expects to have products out on the market offering this level of density in two to four years.
