A:从物理结构上说,磁盘里的信息是储存在磁盘里的磁片上的。这些磁片被划分成一圈圈的同心圆,称为磁道。这些同心圆上的一段称为扇区,磁道和扇区的开头标明了道号和区号等信息。当接收到计算机发来的输入/输出命令后,立即驱动磁头寻找存放数据的磁道,并定位在磁道的上方等待按扇区存放的数据块到来;一旦检索到所要寻找的扇区,便启动读/写电路进行数据的存取。要想了解信息的存储方式,还需要知道磁盘的文件管理机制。 A: In physical terms, the information on the disk is stored on the disk in the disk. These disks are divided into concentric circles in a circle, called tracks. The beginnings of these concentric circles, called sectors, tracks, and sectors, indicate information such as road numbers and area codes. After receiving the input / output command sent by the computer, the magnetic head is immediately driven to search for the track for storing data, and the data block waiting for being stored by the sector is positioned above the track. Once the sector to be searched for is retrieved, / Write circuit for data access. To understand the storage of information, but also need to know the disk file management mechanism.
