Hitachi and Partners Developed 3.9Tbit per Square Inch HDD Technology

November 26, 2010

In col­lab­or­a­tion with the New Energy and Indus­tri­al Tech­no­logy Devel­op­ment Organ­iz­a­tion (NEDO), Hita­chi developed a new hard disk drive tech­no­logy for stor­ing data at a dens­ity of 3.9 Tbit per square inch. The new Tech­no­logy will increase the cur­rent capa­city by 8‑fold by mak­ing it avail­able 24TB in 3.5 drives and 8TB in 2.5 drives.

Per­pen­dic­u­lar record­ing (or Per­pen­dic­u­lar Mag­net­ic Record­ing, PMR) is a recently imple­men­ted tech­no­logy for data record­ing on hard disk “The main chal­lenge in design­ing mag­net­ic inform­a­tion stor­age media is to retain the mag­net­iz­a­tion of the medi­um des­pite thermal fluc­tu­ations caused by the super­para­mag­net­ic lim­it. If the thermal energy is too high, there may be enough energy to reverse the mag­net­iz­a­tion in a…
