摘要： Waste water issued from a wet type desulfurization apparatus and containing thionic acid ions is introduced into ion-exchange towers filled with weak-basic anion-exchange which has to effect anion exchange therein. The weak-basic anion-exchange resin which has adsorbed the thionic acid ions is desorbed by contacting an alkaline solution. The thionic acid ions included in the desorbing solution are decomposed by heating them in the presence of acid. A decomposed solution is issued out of the system after its neutralization.

摘要： A method for manufacturing a magnetic sensor that has a flat upper shield. A sensor stack is formed with a sensor capping layer at its top and a first CMP stop layer over the sensor capping layer and a mask formed over the CMP stop layer. A hard bias layer and second CMP stop layer are deposited over the sensor stack, capping layer, first CMP stop layer and mask. A chemical mechanical polishing process is then performed to remove the mask, leaving a portion of the hard bias layer exposed between the first and second CMP stop layers. An ion milling is then performed to etch back the exposed portions of the hard magnetic bias layer. A reactive ion etching is then performed to remove the remaining first and second CMP top layers. An upper shield can then be formed on a substantially flat surface.

摘要： Embodiments of the present invention help to reduce etching damage at end parts of a magnetoresistive sensor in ion beam etching. According to one embodiment, ion beam etching (IBE) is used in a magnetoresistive sensor track width forming step. This IBE irradiates Ar ion beam to a substrate in a state that the substrate is inclined and further rotates the substrate about its normal as a rotational axis. In a conventional track width forming step, the IBE irradiates the Ar ion beam to the substrate all the time while the IBE is rotating the substrate. By contrast, the IBE according to embodiments of the present invention irradiates the Ar ion beam to the substrate only in a predetermined specific angular range.

摘要： There is provided a perpendicular magnetic recording and reproducing system in which the overwrite erase ratio of a perpendicular magnetic head has been improved to prevent the deterioration of an overwrite property. In the perpendicular magnetic head, a third magnetic pole composed of a soft magnetic layer is formed on the leading side of a recording magnetic pole via a non-magnetic layer, thereby reducing magnetic interference from magnetization on a medium with the recording magnetic pole and preventing the deterioration of the overwrite property.

摘要： According to one embodiment, a CPP structure magnetoresistive head includes a magnetoresistive sensor film between a lower shield layer and an upper shield layer and a longitudinal biasing layer disposed at each side of the magnetoresistive sensor film via a read track width defining insulator film. In the stripe height direction, the length of the longitudinal biasing layer is longer than the length of a second ferromagnetic layer in which its magnetization rotates in response to the external magnetic field. The second ferromagnetic layer is one of the layers comprising the magnetoresistive sensor film. At a stripe height, the surface of each longitudinal biasing layer has a step to change the thickness thereof across the step so that the air bearing surface section thereof has a larger thickness than any other section. Other structures using a magnetoresistive head and methods of production thereof are described as well.

摘要： A magnetic sensor having reduced read gap thickness, reduced signal noise and improved signal to noise ratio. The sensor includes a sensor stack and hard bias structures formed at either side of the sensor stack for biasing the free layer of the sensor. A protective layer is formed over a portion of the hard bias structure, however a portion of the hard bias structure extends upward toward the upper shield and is disposed between the protective layer and the sensor stack as a result of the process used to form the magnetic bias structure. This portion of the hard bias structure that extends toward the upper shield has a reduced magnetization relative to the rest of the hard bias structure so that it will not magnetically couple with the upper shield.
