Abstract
This invention provides a digital data recording and reproducing apparatus and a digital data reproducing apparatus for recording data to a recording medium which can handle instrumental data as the data. In the digital data recording and reproducing apparatus according to the invention, in parallel with the writing of data to a magnetic tape, the written data is read. An error correction code of the read data is decoded and whether errors exceeding an error correcting ability which the code has exist or not is checked. In case of handling normal data, in this case, the same data is rewritten by a retrying process. In case of handling instrumental data, the retrying process is not performed and subsequent to the data having uncorrectable errors, the next data is written. In case of reading data as well, data in which uncorrectable errors exist is also read and transferred as it is.
