Apparatus for magnetically detecting positions with minimum length magnetic information units recorded on a plurality of magnetic tracks

摘要

The present invention relates to an apparatus for magnetically detecting positions and intends to provide a position detecting apparatus of the kind with high accuracy in which when recording magnetic signals of a predetermined length on magnetization tracks, a plurality of recording units are continuously arranged in the direction of the magnetization track and are set as the predetermined recording length, thereby sharpening the output waveform of the signal corresponding to the edge portion of the magnetization recording length. The present invention is suitable for the absolute type having a plurality of magnetization tracks.
