寻道

As described in the front, and now head positioning with precision the extent of continuous improvement, seeking ways and hard disk formatting commands are also great changes have taken place.

正如前边所述，现在随着磁头定位精密程度的不断提高，硬盘的寻道方式和格式化指令也发生了很大的变化。

Compared with the previous, and now the physical hard disk have been some changes in the structure of a direct impact on the realization of the hard drive changes in the way instruction, the most important thing is to seek changes in the way the hard disk formatting result in changes in instruction.

与以前相比，现在硬盘的物理结构发生了一些变化，直接影响到相应的硬盘指令实现方式的变化，其中最重要的就是硬盘寻道方式的变化导致的格式化指令的变化。

Rotational latency is the additional time waiting forthe disk to rotate the desired sector to the disk head.

磁盘访问时间 1 寻道时间 Ts 这是指把磁臂移动到指定磁道上所经历的时间。

In this paper. a novel magnetic head crab track pluck detection way is given by the analysis of etched servo graph for 4000 TPI etched surface servo. It improve the maximum seek track speed of magnetic head greatly, So that magnetic head can seek track at high speak for high track density.

光刻伺服盘是一种新的磁头伺服定位技术［1］，通过对4000TPI光刻面伺服系统的光刻伺服图形结构的分析，本文提出了一种简单可靠的磁头过道脉冲检测方式，可显著提高磁头寻道速度，保证磁头在高道密度下高速寻道。

If you are not satisfied, try one of the Malian Dao, look for more and more goods.

如您觉得不好，不妨去马连道，多品多寻。

To improve the efficiency of disk scheduling, this paper proposed an optimization algorithm of disk scheduling based on the Average Seek Time.

针对如何提高磁盘调度效率的问题，提出了一种基于平均寻道时间的磁盘调度优化算法。

Zero once the damaged track will be the primary boot hard drive and the partition table information will be seriously damaged, resulting in the hard disk can not boot. 0 tracks damaged judge: System self-test pass, but the boot partition C disc lost or directory is missing, there are laws of the hard disk "... creak ... creak" seek the sound of running SCANDISK scanning C disk, in the first cluster a red "B", or can not find Fdisk the hard disk, DM died in the 0 track, the track such a situation that is zero damage!

零磁道一旦受损，将使硬盘的主引导程序和分区表信息将遭到严重破坏，从而导致硬盘无法引导。0磁道损坏判断：系统自检能通过，但启动时，分区丢失或者C盘目录丢失，硬盘出现有规律的"咯吱……咯吱"的寻道声，运行SCANDISK扫描C盘，在第一簇出现一个红色的"B"，或者Fdisk找不到硬盘、DM死在0磁道上，此种情况即为零磁道损坏！

Any topic you want to talk to seeker who speak and read Chinese language.

任何你想对使用中文的寻道者所想讲的话题。谢谢。

Failure is often manifested in the phenomenon of nonpower, hard disk not detected, the disc does not turn heads, such as do not seek.

故障现象往往表现为不通电、硬盘检测不到、盘片不转、磁头不寻道等。

The interval between the end of a disk seek and the time at which the starting block address specified in the I/O request passes the disk head.

从磁盘寻道结束开始，直到磁头旋转到I/O请求所请求的起始数据块位置止，这之间的时间间隔称为旋转延迟。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
