Over the past two decades, the human society went through a digitization process, and with increasing data produced an adopted for every aspect of human life. The demand for data storage has not been slow down. As data migrated into cloud to further reduce cost of data storage, the high capacity HDD with large number of platters are being utilized.
However, the scaling of HDD technology leads to a reduction of data temperature capability and increased energy utilized for each bit read/write operations. One of the poor scaling factors is the size/weight of the recording head assembly associated with increasing number of platters per drive. The random access speed is inverse proportional to the weight of the recording head assembly. Traditional stepping motor has to use higher driving current or larger magnet to compensate, which even with increased cost of materials and higher energy consumption, still will lead to slow down of the drive.
IBT has unique magnet design that is able to improve HDD random access speed and lowers the energy consumption of the HDD by up to 20%.
