Abstract
PURPOSE: To reduce the sliding noise without impairing the fundamental performance by forming the porous and inorganic material on the surface of the ring- type magnetic head made of the ferrite.
CONSTITUTION: Porous and inorganic material 14 is stuck onto entire surface 14 of head cores 2 and 3 each, part 14 more backward than the gap depth end, or at least side wall 15 close to the vibration source among side wall areas 12, 13, 15 and 16 each in the inner space of winding window 1. After this, windings 6 and 7 are applied. As a result, the sufficient absorption of the elastic waves given from the ferrite via material 14 can reduce extremely the occurrence of the noise caused by variation of the magnetization inside the ferrite due to the mechanical rocking caused on sliding surface 5 of the magnetic head. Thus the S/N ratio can be increased with no effect given to the head output.
