摘要
Briefly, in accordance with one embodiment of the invention, a device for use in a magnetic recording read channel adapted to be coupled to a magneto-resistive (MR) read head comprises: an integrated circuit adapted so as to introduce a controllable amount of second-order nonlinearity into the magnetic recording read channel signal path to at least partially offset nonlinearity associated with use of the MR read head. Briefly, in accordance with another embodiment of the invention, a method of reducing nonlinear signal effects in a magnetic recording read channel signal path associated with use of a magneto-resistive (MR) read head comprises the step of: introducing into the read channel signal path a scalable square of the read channel signal.
