Computer Hard Disc Drive - Transfer Function Using Newton's law, a simple model for the read/write head is the differential equation: where J is the inertia of the head assembly, C is the viscous damping coefficient of the bearings, K is the return spring constant, Ki is the motor torque constant, θ is the angular position of the head, and i is the input current. Taking the Laplace transform, the transfer function from i to θ is Using the values J = 0.01 kg m 2 , C = 0.004 Nm/(rad/sec), K = 10 Nm/ rad, and Ki = 0.05 Nm/rad, form the transfer function description of this system. Transfer function: 72
