Abstract

PURPOSE:To enable both-side recording by providing an induction path for a magnetic field between magnetic recording medium layers. CONSTITUTION:On both sides of base layer 12, layers 11 and 11' for a magnetic field induction path made of a material of low coercive force and high magnetic permeability, such as permalloy, are provided and at both the sides of them, magnetic recording medium layers 13 and 13' are provided. The layer for the magnetic field induction path may be provided on only one side and the base layer is also used tp form the magnetic field induction path.
