Distortion of inductive read head signal due to side-written magnetization
We apply a Fourier series model to calculate distortion in an inductive read head signal due to side-written magnetization patterns in thin-film magnetic recording media. This model predicts that a magnetization pattern consisting of in-track longitudinal and transverse track edge magnetizations wil...

| description | We apply a Fourier series model to calculate distortion in an inductive read head signal due to side-written magnetization patterns in thin-film magnetic recording media. This model predicts that a magnetization pattern consisting of in-track longitudinal and transverse track edge magnetizations will produce a signal distorted by the flux from the side magnetization. By using parameters obtained from a direct magnetic image of the patterns, this analysis predicts the morphology and magnitude of signal distortion as a function of pattern dimensions. The implication of this distortion for higher bit densities suggested for the future was found to be significant. The proposed method will offer reliable means to quantitatively assess the effect of side writing at such densities. |
