ABSTRACT:
A technique for controlling the write currents of a magnetic disk recording apparatus includes prolonging the write mode for a given time after completing data writing on a disk by supplying a constant write current to a head according to data to write, gradually reducing the write current for the given time, and cutting off the write current.
