Abstract

PURPOSE: To reduce and eliminate the sliding noise of the magnetic head with the head core composed of the ferrite component, by sticking the plate component featuring the specific value for the product of the density and the longitudinal elastic modulus to the side face of the head core.
CONSTITUTION: Plate component 2 featuring the ρ×E value of 45W200% of the product value between volume density ρ and longitudinal elastic modulus E is stuck to the side face of head core 1 composed of the ferrite component. [The value of the ρ×E value is set preferably to about 0.5×1013W2.2×1013(dyne)2s2/cm6]. In case the material of component 2 is nonmagnetic, the component is stuck to the entire side face of head core 1 (fig. a); while in case component 2 is magnetic material, no short-circuit is given to core gap 3 and the plate component is stuck to the area as close to the sliding surface as possible (fig. b). At the same time, it is desirable that each face excepting the sticking face of component 2 is made parallel or vertical to the sticking face.
