Abstract

PURPOSE:To positively utilize components perpendicular to the magnetizing direction of transverse recording during reproduction by composing a magnetic head of a writing head for the transverse recording and a reproducing head for reading the components perpendicular to the magnetizing directions of a recording medium. CONSTITUTION:A magnetic head consists of a writing head 4 for transverse recording and a reproducing head 6, which is provided opposite to the writing head 4 with a nonmagnetic material 5 between. A gap 7 has much less distance G than recording wavelength lambda in the magnetizing directions 2 and 3. Winding to a magnetic medium 1 is performed by flowing a writing current Iw to the coil 9 wound around the writing head 4 and during reproduction, components Hx perpendicular to the magnetizing directions 2 and 3 are utilized to lead a reading current out of the coil 10 wound around the reproducing head 6.
