Abstract
A magnetic head apparatus arranged such that, for preventing a crosstalk between a plurality of magnetic heads, a crosstalk preventing element is coupled through a switching element in parallel to an erasing coil of each of the magnetic heads and a control section selectively energizes and deenergizes the switching element. This arrangement allows prevention of the crosstalk to the magnetic heads.
