Hardware Description

In 1987, NEC shipped the D3126H, which improved average seek time from 85msec to 35msec by changing the magnetic head movement system from a step motor to a torque motor, and the D3146H which doubled the number of disks while keeping the same magnetic head system, and increased memory capacity to 51MB.
