ABSTRACT:
A magnetic tape read/write head for variable track density forward and backward writing and checking after writing, incorporating a read gap and two larger write gaps arranged off center from the read gap on the axis of tape motion. Each pass of one of two write gaps writes a data band of the width of the write gap. A second pass in the same direction overwrites to some extent the previously written data band so as to define the width of the data track.
