Abstract
Systems and techniques relate to current slew control circuits. According to an aspect, a system implementing the quadratic slew control aspects comprises a disk; a read/write head; and a slew control circuit coupled to the read/write head, the slew control circuit configured to: receive an input current signal, apply a slew current to the input current signal in response to a change in a power setting for the read/write head, and provide an output current signal that is adjusted to a quadratic current slew based on the applied slew current, the output current signal generating an output voltage characterized by a linear slew and controlling a movement of the read/write head over the disk.
