<p><P>PROBLEM TO BE SOLVED: To provide a magnetizing method of a magnetic encoder and a magnetizing device, capable of precisely magnetizing tracks to be magnetized in a plurality of lines adjoining each other. <P>SOLUTION: A magnetic encoder is available by separately magnetizing each line of magnetic encoder tracks 2 and 3 using a magnetic head 10 including a magnetizing yoke 11 and a magnetizing coil 12 while a ring-like magnetic body 1, having ring-like magnetic encoder tracks 2 and 3 in a plurality of lines, adjoining each other as one body, is rotated. In the magnetizing method, when a line of magnetic encoder track 2 (3) is magnetized, a magnetic encoder track 3 (2) of other line is covered with a magnetic shielding mask 5. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
