magnetic resistance sensing circuit associated with the sharing of wealth and culture, a strong magnetic flux converter and its manufacturing method, recording

摘要

the ministry of MR readout circuit associated with the flux and data converter (40) and the manufacturing method of it, the essence of the relationship between 500 - 2500 u212b relatively high magnetic moment material (48) in the upper magnetic pole (44), the use of ub9c8uc2a4 limit ion flux. milling before shared circuit part (42), and the upper surface of the lower part of the recording head, and to add to his play. relatively high magnetic moment and the magnetic flux is CoNiFe, FeN or genetic gap layer (46) of the kind used on similar substances can be realized. then, the magnetic flux and is only 1.the u212b 0 k that only need to be relatively simple ion milling process to remove a small amount of material, and the top of the pole on the side of the material can be in the top of the pole, around have a choice of uc801uc73cub85c may be.
