ABSTRACT:
A digital signal reproducing apparatus comprises a reproducing head for reproducing from a magnetic tape digital signals which are magnetically recorded on n tracks of the magnetic tape, where n is a natural number greater than one, the magnetic tape has a guard band separating each of two adjacent tracks among the n tracks, the reproducing head comprises n reproducing element groups provided in correspondence with the n tracks and each of the n reproducing element groups comprises a plurality of reproducing elements arranged in the tape width direction over a range of a corresponding track and guard bands on both sides thereof, a selecting circuit for selectively obtaining outputs of those reproducing elements opposing a uniform part of the magnetic field intensity distribution of the corresponding track among outputs of the plurality of reproducing elements in each of the n reproducing element groups, which selecting circuit is provided for each of the n reproducing element groups, and an adder for adding outputs of the selecting circuit and for producing a reproduced signal from each of the n tracks.
