| Abstract | A novel intersymbol interference (ISI) removal technique based on the "response function" characterization of giant-magnetoresistive heads is presented. It is demonstrated that the ISI-free readback image that corresponds to the actual underlying magnetization patterns can be extracted from the ISI-distorted readback signal through deconvolution. A new image deconvolution algorithm has been implemented, and it has been shown that it effectively removes the ISI distortions. |
