    摘要： Disc drives are made with an actuator designed with at least one asymmetrical arm having two masses that move out of phase. The arm is modified by removing a portion of the higher-energy (longitudinal) side, the one with the greater total time-averaged strain energy. This modification reduces the phase difference between the first and the second arm, particularly for a relevant frequency range of interest. Disc drives made by this method exhibit a generally reduced out-of-phase motion, enhancing performance during seeking and track following, especially for arms with two heads that interact with surfaces of opposing discs.

    摘要翻译： 盘式驱动器由致动器制成，该致动器设计有至少一个不对称臂，其具有两个不同相位的质量。 通过去除较高能量（纵向）侧的一部分，具有更大的总时间平均应变能的臂来修改臂。 该修改减少了第一和第二臂之间的相位差，特别是对于感兴趣的相关频率范围。 通过该方法制造的光盘驱动器显示出大体上减少的异相运动，增强了追踪跟踪跟踪期间的性能，特别是对于具有与相对盘的表面相互作用的两个头部的臂。
