<p>A magnetic head drive device includes a pair of auxiliary coils, a pair of switch elements respectively connected in series with the pair of auxiliary coils, and a magnetic head. The magnetic head is arranged between node of the pair of auxiliary coils and the pair of switch elements. The switch elements are driven by control of a switch element drive device such that at least one of the pair of switch elements is maintained in an ON state for a predetermined period time upon completion or interruption of information recording by the magnetic head. A current contol device is further provided so as to gradually decrease a current to be supplied to the pair of auxiliary coils during the ON state. <IMAGE></p> |
