ABSTRACT:
A magnetic head for floppy discs has a shielding member surrounding a core and coil of the head so as to prevent the head from being adversely affected by an external magnetic field. The shielding member is a stack of sheets and each sheet is made of magnetic metal such as permalloy and is fixed on a gimbal plate together with the magnetic head. Insulator layers made of thermoplastic resin may be provided between sheets of the stack of sheets to adhere the metal sheets to one another and to electrically insulate the metal sheets from one another.
