通过对光盘轨迹中心和几何中心偏差的控制,规范了光驱光头部份的伺服跟踪条件。随着光驱读盘速度的提高和电脑自身重量的减轻,光盘质量中心的偏移对光驱在高速运行时造成的噪声、振动等负面影响日益突显。光盘质量中心与几何中心的偏移可导致光盘unbalance(动态不平衡)的产生,因此控制光盘的unbalance值,将会有利于改善光盘运行时产生的噪声和振动等负面状况。
Through the control of the track center and geometric center deviation of the optical disc, the servo tracking conditions of the optical head part of the optical disc drive are regulated. With the increase of optical disk reading speed and the reduction of the weight of the computer itself, the offset of the optical disk quality center has become increasingly prominent on the negative impact of noise and vibration caused by the optical disk drive running at high speed. Displacement of the disc center of mass from the geometric center can result in the unbalanced disc. Therefore, controlling the disc unbalance value will help to reduce the negative conditions such as noise and vibration generated during the disc operation.
