摘要： The main magnetic pole piece of a magnetic head for perpendicular magnetic recording preferably has an inverted trapezoidal shape in order to maintain a sufficient recording magnetic field. Embodiments of the present invention enhance the covering power of the protective film around the main magnetic pole piece of the magnetic head and thereby ensure reliability even when the main magnetic pole piece has such a shape. In one embodiment, the protective film for protecting the main magnetic pole piece is formed by a sputtering apparatus while applying a bias, or it is formed by a carousel type sputtering apparatus or the chemical vapor deposition (CVD) technique.

摘要： A thermally actuated head for magnetic head for magnetic data recording having a contact sensor for detecting contact between the head and a magnetic disk. The contact sensor includes a thermal sensor film and first and second leads, wherein the leads extend at least as far from the ABS as the thermal sensor film. More preferably the leads extend slightly further from the ABS than the sensor film so that contact between the magnetic disk and the contact sensor occurs at the leads rather than at the sensor film. The sensor film can be constructed of NiFe, preferably having 30-70 atomic percent Ni or more preferably 40-60 atomic percent Ni or most preferably 40-50 atomic percent Ni. The leads are preferably constructed of one or more of Ru, Rh or Ta or an alloy whose primary constituents are Ru, Rh or Ta.

摘要： Embodiments of the present invention provide a perpendicular magnetic recording head including a coil having small resistance. According to one embodiment, a nonmagnetic insulating layer formed on a main magnetic pole and a magnetic yoke are etched to form a recessed portion. The thickness of a conductive layer is increased by the depth of the recessed portion in a process for forming the conductive layer of the upper coil on the recessed portion to reduce resistance of the coil. Simultaneously with the formation of the recessed portion, a part of a second layer of a connection tab is removed. Simultaneously with the formation of the conductive layer of the upper coil, a space in which the part of the second layer of the connection tab is removed is filled with the same material as that of the conductive layer to further reduce the resistance of the entire coil.
