问题 问答题 论述题

论述分析光盘文件的使用及保管要求。

答案

参考答案:

在借助于光盘技术存储、检索和利用文件与档案时应充分考虑:

(1)注重扫描质量。激光扫描是将纸质文件转化为光盘文件的技术手段,扫描质量直接关系到光盘文件文字、图像的清晰度和还原效果,必须予以高度重视。因此,每台扫描仪都应确定自己的质量标准;为确保所有文件原件用数字图像替代时的质量标准统一,有必要建立一个对所有图像进行全面检查的程序。

(2)建立检索系统。利用光盘技术管理文件的目的是为了便于存取、检索和利用。因此建立、健全完善的光盘检索系统是至关重要的。光盘的检索系统在数字图像程序中应有完善的规定和恰当的安排。

(3)完善保护措施。尽管光盘文件的保护条件和要求相对不高,但在使用和保管时也应考虑:保存的时间性;防止存储的数据遭到自然或人为的破坏;防止再利用中的意外损坏;以及经济因素等方面的问题。应注意:

①对于重要文件,除保存一份原可擦型光盘外,还应刻录一份只读光盘做备份,并定期检查光盘质量,发现问题及时重新刻录。

②保护光盘自身具有保护层的有利其耐久性的结构设计,以及利用其无接触式的信息存取方式。

③改进引起光存储介质失败的不良环境条件,避免外来能量的辐照引起介质失效;避免不良的机械作用引起介质结构变化失效;采用具有防磁、防潮、防静电等动能的储存柜,以利长期保存。

(4)慎重处理原件。在将文件信息转化为光盘文件管理之后,应根据文件特点采取慎重态度处置文件原件。凡具有内在价值的文件,无论处于何种状态,是否制作了视读替代品,都要保留其原件;不能销毁。因为文件原件的原始凭证性是其特殊属性,有的还具有不可代替的唯一性。

Christmas was coming. “Don’t    any presents this year,” Dad said, pointing at the    I hung in the living room. “     your baby brother lives, that’ll be Christmas enough.” As he spoke, his eyes filled with tears. I’d    seen him cry before.
The phone rang early on Christmas morning. Dad jumped out of bed to     it. From my bedroom I heard him say, “What? He’s all right?” He    and shouted upstairs. “The hospital said we can bring Richard home!”
“Thank God!” I heard Mum cry.
From the upstairs window, I watched my parents rush out to the car. I had never seen them so     . And I was also full of joy. What a wonderful day! My baby doll would be home. I ran     . My socks still hung there    , but I knew they were filled with    !
