ABSTRACT:
A magnetic head driving apparatus is provided with a pair of switch elements for switching a direction of a current to be supplied to a magnetic head. ON/OFF operations of the pair of switch elements are controlled in correspondence with an information signal to be recorded so as to modulate a magnetic field generated by the magnetic head in accordance with the information signal. A predetermined time difference is provided between an ON operation of one switch element and an OFF operation of the other switch element of the pair of switch elements.
