MAGNETIC HEAD SUPPORT MECHANISM

PURPOSE:To obtain a magnetic head support mechanism which stabilizes the floating state of a magnetic head slider by providing a fixture with a load spring for resonance attenuation which extends in the lengthwise direction of a load arm and has a friction projection part which is in contact with the top surface of the arm atop. CONSTITUTION:The load spring 21 for resonance attenuation which is provided with at least one hemispherical friction projection part 22 contacting the maximum amplitude position of resonance mode of the arm surface at the atop and bent in a specific curved shape so as to place a constant load on the friction projection part 22 is provided in the lengthwise direction on the load arm 1. Therefore, if the load arm 1 resonates owing to the oscillation of a driving actuator or external oscillation, disturbance during the rotation of a disk medium, etc., the resonance energy is absorbed by the frictional operation of the friction projection part 22 of the load spring 21 for resonance attenuation which is in contact with the maximum amplitude position of resonance mode on the surface of the load arm 1 with the constant load, thereby attenuating the resonance effectively. Consequently, the floating state of the magnetic slider over the surface of the magnetic disk medium is stabilized.
