Vibration-canceling mechanism and head gimbal assembly with the vibration-canceling mechanism

摘要

A vibration-canceling mechanism includes a vibration transfer member of a plane shape inserted between a vibration-origination system having a plurality of resonance frequencies and an object to which vibrations are applied from the vibration-origination system. The vibration transfer member has a plurality of resonance frequencies equal to or near the plurality of resonance frequencies of the vibration-origination system. The vibration transfer member has a plurality of pairs of arm sections for coupling one end section of the vibration transfer member with the other end section of the vibration transfer member. The one end section of the vibration transfer member is fixed to the vibration-origination system and the other end section of the vibration transfer member is fixed to the object so that apparent vibrations of the object are substantially canceled by resonances of the vibration transfer member.
