Massive capacity has been achieved through the enhancement of the head, the media and the record processing technology allowing up to 60GB per disk, maximum 120GB per drive (2 disks) high capacity. The enhancement of spindle motor driving technology and the power reduction of controller circuit enable to minimize by 1.6watt at read operation. It is about 0.4watt or less power consumption in compare with 4, 200rpm drives. The enhancement of spindle motor driving technology and the stiffness of mechanism have achieved to reduce the acoustic noise of 2.3 Bels at idle operation. The enhancement of head holding structure to read and write the data of the media enable in high shock tolerance. The drives withstand up to 300Go-p (duration 2ms) operating shock.
