ABSTRACT:
A light signal reading method in which a first light beam modulated to a polarized state in accordance with information magnetically recorded on a recording medium is caused to interfere with a second light beam of a frequency different from that of the first light beam, and the information being detected as a variation in the intensity of the interference light, and an apparatus therefor.
