| 摘要 |
A method of high density magnetic recording with a single bipolar signal field using a magnetic recording head having a recording gap that is inductively coupled to a relatively moving thin-ferromagnetic-film recording medium of a thickness that is insufficient to support Bloch walls, i.e., can only support Neel walls, between adjacent domains and having an easy axis that is orthogonal to the direction of relative movement of, or parallel to, the recording gap length. The recording medium's interdomain Neel walls are formed with the magnetization within the interdomain walls all having the same directional rotational, i.e., winding, sense, e.g., clockwise or counterclockwise, by utilizing a magnetic recording head that has its recording gap parallel to the recording medium's easy axis, and that has a drive line that provides a bipolar signal field that is oriented at an acute angle to the recording gap so that the gap field and an orthogonal component of the driveline provided signal filed are applied orthogonally and parallel, respectively, to the easy axis direction of the recording medium.
