Abstract: A system for treating and recycling rainwater, including at least three stages constructed wetlands disposed along a sloped surface. Each stage constructed wetland includes a coarse gravel layer, a fine gravel layer, an improved soil layer, and wetland plants from bottom to top. Slopes are disposed at two sides of the upper part of each constructed wetland and are different in heights. An intermediate overflow pipe is disposed at the top of the slope between every two adjacent constructed wetlands. A last overflow pipe communicates with a municipal rainwater pipe. The coarse gravel layers of every two adjacent constructed wetlands are connected by connecting pipes. A perforated water collecting pipe is disposed at front ends of the connecting pipes. A water outlet pipe is disposed in the bottom of the coarse gravel layer of a last stage constructed wetland and is connected to a clean water reservoir.

Abstract: A magnetic write head having a write pole with a novel configuration improving write field strength and field gradient while also reducing adjacent track interference and far track interference. The write pole is configured with a pole tip portion that has a narrow track width, preferably 15-30 degrees and a main yoke portion with a larger flare angle of about 45 degrees. The write pole also has an intermediate portion located between the pole tip and main pole portions. The intermediate portion includes a first portion adjacent to the pole tip that has a flare angle greater than the flare angle of the main yoke and has a second portion with a flare angle less than the flare angle of the yoke.

Abstract: A magnetic write head having a write pole and a trailing, wrap-around magnetic shield formed over the write pole and separated from the write pole by a non-magnetic trailing gap layer and non-magnetic side gap layers. The write head includes a remnant magnetic seed layer, that while being used to facilitate electroplating of the magnetic shield, is left intentionally extending beyond the back edge of the magnetic shield. This extended portion of the magnetic seed layer acts as a shunt for magnetic flux and prevents data erasure due to over-writing.

Abstract: In one embodiment, a magnetic head includes a main pole having a trapezoidal cross-section at a media-facing surface thereof and a flared shape with a greater width in a cross-track direction at positions away from the media-facing surface, a leading shield positioned near a leading side of the main pole, wherein a leading gap is provided between the main pole and the leading shield, side shields positioned on both sides of the main pole in the cross-track direction adjacent the media-facing surface of the main pole, with side gaps provided between the main pole and both of the side shields, and a trailing gap provided on a trailing side of the main pole at the media-facing surface thereof, with a throat height of the side shields being less than the throat height of the side shields at a position closer to the trailing gap than the leading gap.

Abstract: The application discloses a magnetic pole assembly having a pole tip arranged in a magnetic flux path and side shields separated from the pole tip by non-magnetic gap regions. The side shields are shaped to provide a differential shielding effect alongside the pole tip. As described, the sides shields are shaped to provide a non-magnetic gap region having a width that increases in the downtrack direction along a length of the pole tip. The increasing non-magnetic gap region alongside the pole tip provides a smaller non-magnetic gap region separating the pole tip from the side shields at the leading edge than the non-magnetic gap region separating the pole tip from the side shields at the trailing edge of the pole tip.

Abstract: A write head for use in a magnetic disk drive and methods of manufacturing the same. When a non-magnetic reactive ion etching (RIE) stop layer is used in a damascene main pole fabrication process, the leading edge shield and the side shield have a magnetic separation. By replacing a non-magnetic RIE stop layer with a magnetic RIE stop layer, no removal of the RIE stop layer around the main pole is necessary. Additionally, the leading edge shield and the side shield will magnetically join together without extra processing as there will be no magnetic separation between the leading edge shield and the side shield.
