摘要 针对光盘存储技术的发展和星载光盘机的应用需求,着重分析了失重状态下光盘机的工作性能。分析指出失重影响的关键部件是小车运动部件;文章详细分析了失重状态下,光头运动部件寻道和聚焦的工作情形;并从这些分析得出结论,指出失重状态下,光盘机仍能正常工作。 This paper analyzes the operating characteristic of optic-storage drive at zero gravity. In this article, development of memory technology and requirement of satellitic application are introduced. The paper point out that the key component is the dolly motion part at zero gravity. Accordingly, detailed analyzing is given for opto-mechanical-moving-assemhly seeking and focusing at zero gravity. The analyzing sums up that the optic-storage drive could operate normally at zero gravity.
