Claim:
A non-tracking reproduction system data reproducing apparatus in which a plurality of reproducing heads scans the same track on a tape-like recording medium or a single reproducing head scans the same track on said tape-like recording medium a plurality of times, reproduced data obtained by respective scanning is error-corrected at every predetermined recording block by using inner parity, reproduced data error-corrected by said error correction is written in a memory and reproduced data read out from said memory is error-corrected by using outer parity, comprising: identifying means for setting tracks of the number of a part of the rear side of tracks of the predetermined number serving as the minimum editing unit to a pre-writing priority area and remaining tracks to a post-writing priority area, respectively, and determining whether or not reproduced data of a recording block having the same identification data as that of a recording block has already been written in said memory with respect to each said recording block reproduced from said pre-writing priority area and which is error-corrected by using said inner parity; and control means for allowing reproduced data of the recording block of which reproduced data was not yet written in said memory as determined by said identifying means to be written in said memory and inhibiting reproduced data of the recording block of which reproduced data was already written in said memory as determined by said identifying means from being written in said memory.
