The present invention relates to a non-tracking VTR apparatus. The data
reproducing apparatus is characterized in that, of tracks of the
predetermined number serving as the editing unit, tracks of a part of the
rear side are set to a pre-writing priority area and the remaining tracks
are set to a post-writing priority area, with respect to each recording
block reproduced from the pre-writing priority area and which is
error-corrected by C1 error correction, it is determined whether or not
the reproduced data of the recording block with the same ID as that of
the recording block is written in the memory. The reproduced data of the
recording block in which the reproduced data was not written is written
in the memory and the reproduced data of the recording block in which the
reproduced data was written is inhibited from being written in the
memory.
