ABSTRACT:
A write current is set to be an optimum write current. The write current is supplied to a recording head when information is recorded on a recording medium. First margin characteristics are measured which are used for obtaining a lower limit value of the write current to be supplied to the recording head. Second margin characteristics are measured which are used for obtaining an upper limit value of the write current to be supplied to the recording head. As the lower limit value of the write current, a write current value is set for which a margin has a predetermined value in the first margin characteristics. As the upper limit value of the write current, a write current value is set for which a margin has a predetermined value in the second margin characteristics. As the optimum write current, a write current is set which has a middle value between the lower limit value of the write current and the upper limit value of the write current.
