摘要： PROBLEM TO BE SOLVED: To provide a high-sensitivity magnetoresistance effect type magnetic head in a structure comprising two free magnetic layers while output drop decrease to a ferromagnetic layer is small. SOLUTION: In the magnetic head using a magnetoresistance effect element, the magnetization of two free magnetic layers is set to be in mutually opposite directions and at nearly 45° to a surface facing a medium by a current magnetic field for detection, thus obtaining reproduction output approximately two times larger than before. By arranging the ferromagnetic layer only at the side of facing the medium, the sensitivity of the free magnetic layer at the side of facing the medium is increased, thus obtaining further large reproduction output.

摘要： PROBLEM TO BE SOLVED: To provide a highly sensitive magnetresistive magnetic head which is composed of two free magnetic layers and has a structure less in output reduction caused by a bias application layer, and to provide a magnetic recording device using the magnetic head. SOLUTION: In the magnetic head using a magnetresistive element, the magnetization of two free magnetic layers are defined as almost 30 to 60° with respect to a medium facing surface in mutually opposite directions, thereby obtaining a reproduction output about twice as compared with conventional way. A bias application layer is arranged only on the surface side facing the medium facing surface, so that the sensitivity of the free magnetic layer of the medium facing side is increased to obtain a larger reproduction output.

摘要： PROBLEM TO BE SOLVED: To cause a circuit to operate correctly in its entirety, when achieving the circuit equating with one functional macro by using a plurality of divided chips, with a skew brought about by dividing the circuit into the plurality of chips automatically adjusted. SOLUTION: The functional circuit constituting one functional macro is divided and mounted on the plurality of chips while generating a plurality of inner block signals with their phases different from each other based on a referential clock signal. Based on the result of a test operation performed by using a selected inner clock signal, the phase of a clock signal supplied to functional circuits in the chips is adjusted to obtain a clock signal of an optimum phase from among the plurality of inner clock signals. The skew brought about by dividing the circuit into the plurality of chips is automatically adjusted to cause the circuit to operate correctly in its entirety. COPYRIGHT: (C)2007,JPO&INPIT
