<p>A downstream magnetic shield (21) which is integrally formed with a write pole section (19) to make up a magnetic recording head. The shield and the write pole tip (27) are located relatively close together, providing a small gap there between, so that magnetic flux (39) which fringes from the magnetic write pole tip is intercepted by, or has an incentive to pass directly to, the shield. Accordingly such fringing flux does not pass through the recording medium, and hence if a data bit has been written into the recording medium its dipole identity will not be weakened by the fringing flux of a subsequent data bit being written into the magnetic recording medium. In addition the present device provides magnetic flux shielding means (43, 53) for the tracks along side of the track being presently written so that the fringing flux does not disturb the dipole identity of the bits recorded in the adjacent tracks.</p> |
