業１品質１両面において量産管理が難しいという欠点が
ある。The vibration damping means of the conventional magnetic head described above uses a material that is coated with gel-like natural vulcanized rubber and changes over time to become rubber-like. In addition to the need to avoid contact with parts, the amount, thickness, shape, etc. will be irregular, so the vibration damping effect will vary widely, and mass production management is difficult in terms of work, quality, and both aspects.
本発明は、可撓性媒体に接触して記録再生消去等を行う

とを特徴とする。The present invention is a support structure for a magnetic head that performs recording, reproducing, erasing, etc. by contacting a flexible medium, and is characterized in that a gimbal spring to which a magnetic head is attached is attached to a holding part via a vibration absorber.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

ある。The present invention described above fixes the gimbal spring on which the magnetic head is attached to the support body through the vibration absorber, thereby controlling the magnetic head generated by the magnitude of friction between the magnetic head and the medium, the deflection of the gimbal spring, and its return force. This speeds up the attenuation of vibrations and also absorbs and attenuates vibrations transmitted to the magnetic head from the support, reducing the vibrations of the magnetic head that occur during media sliding by a factor of 11, preventing abnormal wear of the magnetic head. This has the effect of reducing damage to the medium, as well as read/write errors caused by these phenomena.
また、振動吸収体として板状のゴム等を支持体に固着し
て用いるため製造工程で加硫時間を必要とせず、振動減
衰の効果のバラツキも小さくすることができる。Further, since a plate-shaped rubber or the like is used as the vibration absorber by being fixed to the support, no vulcanization time is required in the manufacturing process, and variations in the vibration damping effect can be reduced.
