摘要： In a method for manufacturing a perpendicular magnetic recording head, a groove defined by the inner side surfaces of a first nonmagnetic layer and the top surface of a main magnetic pole layer is formed using the difference in etching rates for dry etching between the main magnetic pole layer and the first nonmagnetic layer. An auxiliary magnetic pole layer is formed on the groove with a nonmagnetic material layer disposed therebetween. A projection integrated with the auxiliary magnetic pole layer is formed in a recess of the nonmagnetic material layer on the groove. This projection extends toward the main magnetic pole layer.

摘要： A signal demultiplexer includes serially-connected 2-demultiplexing filter banks, including band-stop filters and down-samplers for culling sampling frequencies of output signals from filters to 1/2. When the 2-demultiplexing filter bank operates on four types of filters, first to fourth filters in an ascending order of frequencies, 2-demultiplexing filter bank is arranged in one of two configurations so that a first filter bank contains at least the first filter or the second filter, or a second filter bank contains at least the third filter or the fourth filter. The filter banks are connected in such a way that signals processed through the first filter are processed by the first 2-demultiplexing filter bank in a next-stage; signals processed through the second filter are processed by the second 2-demultiplexing filter bank in a next-stage. Signals processed through the third filter are processed by the first 2-demultiplexing filter bank in a next-stage; and signals processed through the fourth filter are processed by the second 2-demultiplexing filter bank in a next-stage.

摘要： A perpendicular magnetic recording head includes an auxiliary magnetic pole layer exposed at a surface facing a recording medium, a main magnetic pole layer deposited on the auxiliary magnetic pole layer with an insulating layer therebetween, a coil layer for applying a recording magnetic field to the auxiliary magnetic pole layer and the main magnetic pole layer, and a connecting layer placed on the auxiliary magnetic pole layer toward the back from the surface facing the recording medium. At the surface facing the recording medium, the upper base of the main magnetic pole layer is wider than the lower base so that the width in the track width direction of the main magnetic pole layer gradually increases with distance from the auxiliary magnetic pole layer. A method for making such a perpendicular magnetic recording head is also disclosed.

摘要： A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.

摘要： A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe-M-O alloy, an Fe-M-T-O alloy or an NI-Fe-X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.
