| Abstract: | At high track density, three dimensional effects are not negligible for the evaluation of narrow track head characteristics such as crosstalk and intertrack guard. In particular, the side fringing fields of narrow track heads cause effective track width to be greater than the physical width. The side fringe fields of narrow track heads have been analyzed in the paper, and analytic expression for the three dimensional field distribution obtained. Then certain consequences are considered: recorded track width and isolated pulse characteristics. |
