Abstract
A data recording and reproducing apparatus promotes error-free and speedy exchange of data between separate recording media. When desired primary data is to be recorded on a master recording medium, secondary data is added to the primary data in order to detect and correct data errors. The primary and secondary data are recorded on the master recording medium in a plurality of series which differ in recording sequence from each other. The primary data is reproduced from the master recording medium together with the secondary data for the different series at the same time, regardless of their recording sequences. The reproduced primary data is allowed for error check and correction based on the secondary data and is recorded in the slave recording medium.
