Title: Magnetic shielding material used for varying magnetic field
Inventor: OTSUKA HIROAKI
IPC: H05K9/00
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To block a varying magnetic field by alternately laminating at least one layer of NbTi and high conductivity metal layers and by interposing barrier layers of Nb or Ta between the NbTi alloy layers and the high conductivity metal layers and by forming one or both of the outermost layers from NbTi alloy, Nb, or Ta. SOLUTION: A magnetic shielding disk is formed in which thirty NbTi alloy layers 1 and twenty nine copper layers 2 are alternately laminated and Nb layers 3 are interposed between the NbTi alloy layers and the copper layers, and the outermost layers are formed of Nb. The Nb layers 3 as barrier layers are interposed between the NbTi alloy layers and the copper layers so that the high conductivity metal such as copper and Ti in NbTi do not form an intermetallic compound in the hot rolling step of the manufacturing process. Generation of an eddy current due to a varying magnetic field is suppressed by forming the outermost layers from NbTi, Nb, or Ta. Thus, under a strong direct current magnetic field, a varying magnetic field can be shielded without generation of an eddy current accompanied with heat generation.

Abstract: PROBLEM TO BE SOLVED: To identify a track within the range equivalent to plural tracks and to expand the range of position detecting by having a position area different from a phase difference between plural position areas. SOLUTION: Positional information is identified from a phase difference of a vector between a position area (o1) and a position area (o2) with a servo circuit. When a reference track is expressed by a track Tr0, a phase difference of both o1 and o2 is 0 in the track Tr0, a phase of o1 is -90 deg., a phase of o2 is -135 deg. and a phase difference between a vector o1 and a vector o2 becomes +45 deg. in a track Tr1 which is jumped one track from the reference track Tr0. The phase of o1 is -180 deg., the phase of o2 is -270 deg. and a phase difference between the vectors becomes -90 deg. in a track Tr2 which is jumped two tracks from the reference track Tr0. Therefore, reference tracks of tracks Tr0 to Tr7 are identified from the phase difference between the vector o1 and the vector o2.
