The method includes the following steps: depositing a non-magnetic layer (3) of sufficient thickness; anisotropically etching the non-magnetic layer to form a steep wall of suitable dimensions at the required position of a flux guide; depositing a magnetic material to form a magnetic layer (9) on the wall in such a manner that the magnetic layer has a thickness corresponding to the required track width; removing undesired deposits of magnetic material but maintaining the magnetic layer on the wall; depositing an insulating material (19a) to cover the magnetic layer.

Design the structure of high performance Low-E film including its material and thickness of every layer according to basic optical theory. Carry out an innovative work to calculate its optical performance by characteristic matrices and optical admittance. Compare the results with those we get by traditional measurement.3. Prepare Low-E films with RF magnetron controlled reactive sputtering. The result shows that in the visible region (380nm-780nm), the highest transmittance is 82.4% while the average value is 75%. In the NIR region (780nm-2500nm), the average transmittance is 16.2%. These characters can fit the demand of the glass used in architecture and cars, and also in other applications.4. We novelly use the material Titanium as protective layer to solve the problem that Ag layer would disappear when depositing the second TiO_2 layer. As the protective layer, Ti does not increase the number of targets so as to lower the costs. The thickness of the protective layer Titanium is adjusted by controlling of sputtering time. Results shows the Low-E films get the best optical character when the sputtering time of Titanium is 20 seconds5. We novelly proposed a new transmittance quality factor Q=_·(?_-__ to evaluate the performances of Low-E films, which makes it easier to judge the qualities of Low-E film.6. The photocatalysis of Titanium dioxides is researched and introduced into Low-E films. Sb-doped TiO_2 thin films are prepared. Its photocatalysis and hydrophilicity are measured.

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.
