Long-Wavelength Response of Magnetic Heads with Beveled Outer Edges
The long-wavelength response of magnetic reproduce heads with beveled outer edges has been numerically computed. To show contributions from both cross-sectional geometry and head (track) width, several beveled heads have been studied and compared with rectangular heads for two limiting cases: infinite head width and zero head width. The calculations demonstrate that the long-wavelength oscillations associated primarily with the length of the rectangular head with zero width are much stronger than those of the corresponding head with infinite widthl. Head performance can be greatly improved, however, with a proper beveled cut which greatly decreases these oscillations and lessens sensitivity to head width.
