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.
