ABSTRACT:
A dictating machine having a revising function, records a correction signal onto a magnetic tape in superimposition with an originally recorded content when correcting the originally recorded content or adding a content to the originally recorded content so as to accurately indicate a position where the correction or the addition is required, without erasing the originally recorded content. The dictating machine is capable of recording a new content onto the magnetic tape with a large degree of freedom without erasing the originally recorded content, because the new content is recorded on a track on the magnetic tape which is different from the track on which the original contents are recorded.
