When the main body 1 is loaded in the cassette insertion opening B of a reproducing device C, the converter 2 is brought into contact with a magnetic head H through an electrical insulation layer 5, and is fluctuated in an inner frame 3, and receives the pressure of an elastic pressure member 4 at a back plane, and is abutted with the head H with a gap length regulated by the thickness of the insulation layer 5. The electrical signal of the reproducing device inputted from a connector 7 is converted to a magnetic flux at the converter 2. Therefore, since the insulation layer 5 is interposed, a noise component is prevented to be inputted to the reproducing device, and a transmission/reception can be maintained stably regardless of the position of the head.

Abstract: PURPOSE:To obtain reduced iron with high productivity by mixing iron oxide powder with a specified amount of a specified alkali metallic compound and reducing the mixture with solid carbon as a reducing agent. CONSTITUTION:Iron oxide powder such as mill scale is mixed with 0.5-30wt% one or more kinds of compounds selected among the carbonates, hydrogencarbonates, sulfates, nitrates, acetates, sulfides, halides, oxides and hydroxides of alkali metals such as Na.
