Title: Magnetic encoder
Inventor: YAMASHITA SHINJI
IPC: G01D5/245
Filed: 1990-05-11
Abstract: PURPOSE:To obtain a highly accurate magnetic encoder by providing such a pattern row at both sides or at one side of a pattern row written with a predetermined pitch that has the phase different from that of the latter pattern row with specific degrees and the direction of magnetization opposite to that of the latter pattern row. CONSTITUTION:A magnetic pattern row 8 is constituted of a first row 8A of magnetic patterns confronting to a magnetoresistance element (MR element) 5 and a second row 8B of magnetic patterns having the phase different by 180 from that of the row 8A and the magnetizing direction opposite to that of the row 8A. In this constitution, a magnetic flux runs less from strong magnetic parts (a), (b) in a widthwise direction of the row 8A to a weak magnetic part (c) where the pitch is changed. Therefore, the resistance of the element 5 is changed in accordance with the strength of the leaking magnetic field due to the pattern row 8A, whereby pseudo since waves and rectangular waves resulting from shaping of the pseudo sine waves are obtained. It is effective as well when the second row of patterns is only at one side of the first row. In this manner, a highly accurate magnetic encoder with high resolving power can be obtained by providing a second row of patterns adjacent to both sides or one side of a first row of patterns.
