Identification method for level and upright assembling of optical disk driver |
摘要 |
An identification method for level and upright assembling of optical disk driver is proposed. The laser lens of optical disk driver has different displacement for different arrangement of the optical disk driver. The added signal Sub-beam add takes different time to reach peak value for different arrangement of the optical disk driver. The assembling orientation of the optical disk driver can be discriminated and the auto balance system will have better performance. The speed profile can be correctly designed; and the vibration and the noise of the optical disk driver due to imbalance in high-speed rotation can be prevented.
