ABSTRACT:
A magnetic recording and reproduction method includes the steps of recording a plurality of tracks which make a unit for a signal process for data detection by means of a recording head on a magnetic recording medium, and reproducing signals of the plural tracks by a plural number of times in different positional relationships to the tracks by means of a reproduction head which can reproduce a signal across the plural tracks of the magnetic recording medium, collecting the reproduction signals in the unit and performing a signal process for the unit to produce reproduction signals for the individual tracks.
