ABSTRACT:
To improve recording of data on a magnetic recording medium such as a magnetic tape, amplitudes of write signals supplied to a magnetic head are modified, dependent on distances between edges of the write signals. The modification occurs such that, given a short spacing, a respective write signal has a greater value than given a large spacing. Amplitudes of the write signals are modified in three steps when the GCR method is employed as a writing method for recording the data, distances of the edges of the write signals being capable of assuming three different values.
