Title: Magnetic disk device
Inventor: YADA HIROAKI
IPC: G11B21/10
Filed: 1985-03-08
Abstract: PURPOSE:To make a disk face exclusively used for servo unnecessary, and to make the device resistant to thermal expansion, and to obtain continuously servo information by arranging tracks exclusively used for servo at equal intervals at a rate of 1 per N data tracks (N is a natural number) on a magnetic disk face. CONSTITUTION:Plural data tracks DT and an exclusive servo track ST are arranged successively at equal spaces on a disk face of a magnetic disk 1. The relation between data tracks DT and exclusive servo track ST is N data tracks (N is a natural number) is shown by one exclusive servo track. Signals different from the data tracks are recorded on the exclusive servo track ST. For instance, a continuous square wave entirely different in occupied band width from the data tracks DT is recorded on the exclusive servo track. Thus, signals from data tracks DT and signals from the exclusive servo tracks ST can be distinguished by a simple circuit such as a filter etc. when reading servo information using a magnetic head.

Title: Method for measuring field pattern of electric field or magnetic field
Inventor: KURAUSU ABURAHAMUUFUKUSU
IPC: G01R33/10
Filed: 1991-02-18
Abstract: PURPOSE: To best measure a pattern of a field itself emitted from a current source by assigning a weighing coefficient calculated at individual measurement points to a vector of a background field. CONSTITUTION: A vector SN(M) indicates a point in a measured value partial space MR1 , while all measured value spaces are expanded by signals of sensors G1 , G2 , G3 and have a dimension N. If a signal vector closest to a measured value SN(M) in a vector SN(Q) is obtained without compensation related to a background field SN(B), a solution in the space MR1 is obtained, but since the solution is at a source measurement position including an error, a solution in the vicinity of a compensated measurement signal SN(M)-SN(B) is obtained by subtraction of the background field SN(B), that is in a measurement partial space MR2 . A sweighing function W for the corrected vector SN(B) is repetitively calculated by error minimization so that a synthesized vector WSN(B) approaches an answer as close as possible.
