The method involves determining a total length of the linear scale (1). The binary sequence is generated based on a binary pseudorandom code random numbers. A desired pitch width is determined as a function of the total length of the linear scale and the number of binary digits of binary sequence. An absolute magnetization track of the linear scale is produced. An incremental magnetization of linear scale is made by direct addition of absolute track with nominal width (7) of each division of North pole (2) and South pole (3) of linear scale. |
