摘要: 本论文的目的在研究薄型光碟机的振动问题,谋求降低薄型光碟机和光碟片之间的资料传输错误率。随着高倍速光碟机的发展,笔记型电脑越来越普及化,以及顾客对品质及规格的要求越来越高,对于笔记型电脑里的薄型光碟机的性能要求也越高。光碟机必须追求更轻薄,且更有效率降低光碟机读取头和光碟片之间的资料传输错误率。发生振动及资料传输错误率增加之原因,包括光碟机内部因光碟片旋转产生结构和读写头的振动,甚至属于紊流的气流回旋。本研究探讨薄型光碟机读片错误率之成因,并且提出改善对策。黏贴砂纸和镀膜在上盖,以改变上盖和光碟片之间的空间及流场表面之粗糙度,以降低光碟片旋转所造成之结构振动,进而减少读/写错误率。
The objective of this research is to reduce vibration in slim type optical disk drives and transmission data error rate. With the notebook computers more and more popular and customer's demand for quality, slim-type optical disk drives must be light and thin. Vibration and transmission data error rate result from disk rotation and airflow of turbulence form. This study investigates the occurrence of transmission data error in slim optical disk drives and proposes countermeasures. We use abrasive paper and paperboards pasted on the top cover to change the space and make air flow exposed to the surface roughness between the top cover and disk, in order to reduce vibration and transmission data error rate in slim-optical disk drives.
