术语 | missing clock |
释义 | missing clock 消除时钟(法) In magnetic disc recording using double frequency recording; a method of marking the beginning of sectors by eliminating one clock pulse in each of two adjacent bytes of each sector header. The distinctive pattern is recorded during disc initialization and is detected and counted by circuitry to locate a particular sector. The method is termed soft sectoring as contrasted to “hard sectoring”in which sectors are identified by “sector slots”. 在利用双频记录的磁记录技术中, 对每一个区段首部的两个相邻字节中的每一个,用消除一个时钟脉冲来标明区段开始 的一种方法。在磁盘初始化过程中记录特殊模式,并在定位一个特定区段时用电子电路来检 测和计数这个特殊模式。与靠“区段槽”来识别区段的“硬分段”相反,这种方法称为软分段。 |
