magnetic disk

基本解釋

When you send a message, your voice is digitized and stored on a magnetic disk for later retrieval.
你如果發(fā)送一條信息，你的聲音被轉變成數字存儲在一個以后可以恢復的磁片上。
In the whole history, the non-volatile storage of the RDBMS architecture is the magnetic disk from the beginning.
縱觀數據庫的發(fā)展歷史，其架構中的永久性數據存儲介質一直采用傳統(tǒng)的磁性硬盤。
The magneto-optic head flies much farther from the disk surface than a magnetic disk head, and the magnetic material is covered with a protective layer of plastic or glass;
光電磁頭距離盤面的距離比磁頭遠，并且磁介質上覆蓋有塑料或玻璃的保護層；

And when you actually wanna store information on disk, can you actually use, as we'll see in a moment, magnetic particles.
當你想在硬盤中存儲信息時，我們將會用到后面，我們會談論的一種稱之為磁性粒子來實現(xiàn)它。

Much of these increases in storage capacity will involve the introduction of technologies pioneered in the development of magnetic disk drives.
FORBES: Magnetic Tape Turns 60
The magnetic disk backs up all files residing in the NAND, protecting the user from inevitable NAND wear and preserving it for the more hot data handling.
ENGADGET: Western Digital builds 5mm-thick hybrid hard drive, Ultrabook makers sign on early
Although magnetic tape sitting in slots in a tape library uses very little energy data latency is high, spinning magnetic disk drives have lower latency but they can use up a fair amount of energy.

磁盤
Due to the differences between flash memory and magnetic disk, traditional storage management techniques, which are based on magnetic disk, could not be directly applied on flash memory.
而現(xiàn)有的基于磁盤的存儲管理機制無法直接支持閃存設備,其原因在于閃存與磁盤在物理結構、存取方式等方面均存在著顯著的差異。
