available head

With sequential access, the disk head can move directly to the next available track on the disk.

使用顺序访问，磁盘头可以直接移动到磁盘的下一个可用磁道。

Still, sometimes it's useful to know exactly what is available; you never know when creativity will strike and you'll need the HEAD request!

不过，有时确切地了解目前什么可用也是非常有用的；您永远不会知道何时创造力就会迸发或者何时需要 HEAD 请求！

But when we deliberately and specifically add downtime into our lives, we become available for God to use us as we head into this decade of destiny.

但是当我们有意的在我们的生命中加入休息的时间，对于上帝我们将变得有用去迎接生命里的这一个十年。
