magnetic disk

基本解释

When you send a message, your voice is digitized and stored on a magnetic disk for later retrieval.
你如果发送一条信息，你的声音被转变成数字存储在一个以后可以恢复的磁片上。
In the whole history, the non-volatile storage of the RDBMS architecture is the magnetic disk from the beginning.
纵观数据库的发展历史，其架构中的永久性数据存储介质一直采用传统的磁性硬盘。
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;
光电磁头距离盘面的距离比磁头远，并且磁介质上覆盖有塑料或玻璃的保护层；

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.

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.
而现有的基于磁盘的存储管理机制无法直接支持闪存设备,其原因在于闪存与磁盘在物理结构、存取方式等方面均存在着显著的差异。
