ABSTRACT:
A discrete track recording method records information on a magnetic recording medium having mutually adjacent tracks that are separated in advance by a groove. The discrete track recording method carries out a recording using a recording head having a core width in a range greater than or equal to a first value CW1and less than a second value CW2satisfying CW1<CW2with respect to a first magnetic recording medium having a first track pitch TP1, and carries out a recording a recording head having a core width in a range greater than or equal to the second value CW2and less than a third value CW3satisfying CW2<CW3with respect to a second magnetic recording medium having a second track pitch TP2satisfying TP1<TP2.
