Abstract
An apparatus with ring shape sleeve is provided. The apparatus is attached to a shaft and moves around the shaft, the varieties of the apparatus comprise objective lens holder of pick-up head. The characteristic of the invention is that apparatus and shaft are attached by ring shape sleeves where not only thickness of any ring shape sleeve is thin enough such that draft angle effect is negligible but also ring shape sleeve can be inlayed in the apparatus or be molded integrally with the apparatus. Therefore, not only shaft and apparatus are rigorously attached but also the space between shaft and apparatus is significant decreased. Thus, dynamic behavior of the apparatus is more controllable and yield of the apparatus is improved.
