Abstract: In apparatus comprising n(n>/=, 2) heads H for reproducing digital information from a recording medium having a plurality of parallel tracks and digital information recorded thereon as n-channel digital signals, the information in the reproduced signals is stored in a storage means 204 and discriminating data is obtained for determining which of the n-channel digital signals reproduced correspond to the reproducing heads. The address used for accessing the storage means 204 for performing a predetermined processing of the digital signals is shifted in accordance with the discrimination data.
