    • Embodiments of the present invention provide a rotating disk storage device having a mechanism to reliably retract an actuator into a retraction area in the event that the power supply is suddenly interrupted. A bias chip is embedded in a coil support that supports the voice coil. When a head stays in an access area, the bias chip is away from an end of the voice coil magnet. Therefore, no influence of the magnetic leakage flux is exerted on the bias chip. When the head is in a retraction area, the bias chip is attracted under the influence of the magnetic leakage flux of the voice coil magnet, which thereby produces bias torque causing an actuator to pivotally move in a retraction direction. Accordingly, the bias torque can be utilized as energy for retracting the actuator immediately after power shutdown.
    • 本发明的实施例提供了一种旋转盘存储装置,其具有在电源突然中断的情况下将致动器可靠地缩回到缩回区域的机构。 偏置芯片嵌入在支持音圈的线圈支架中。 当头部停留在通路区域时,偏置芯片远离音圈磁铁的一端。 因此,不会对偏置芯片施加磁漏磁通的影响。 当头部处于退避区域时,偏置芯片在音圈磁体的磁漏磁通的影响下被吸引,由此产生使致动器沿回缩方向枢转运动的偏置扭矩。 因此,偏置扭矩可以用作在停电后立即回缩执行器的能量。
