Since then, technologists have improved the effect, and it is now widely used to detect the tiny patches of magnetism that store information on high-density disk drives.

从那时起，技术人员不断地完善这个技术的效果，现在被广泛用于检测在高密度磁盘驱动器中存储信息的微小磁性小块。

When combined, the cache capacity on the drive, the disk algorithms used, the interface speed, and the areal density, produce a disk transfer time.

驱动器上的缓存容量、所使用的硬盘算法、接口速度和磁录密度组合到一起，就构成了磁盘传输时间。

Track density can be greatly enhanced by employing optical servo technology in a disk drive.

在磁盘驱动器中借助光伺服技术可以大幅度提高道密度。

It is also a vital component of high-voltage wires, magnetic coatings for high-density hard disk drives, fiber optics, fiberglass, catalytic converters and spark plugs.

The lower density means dramatically less drag force acting on the spinning disk stack so that mechanical power into the motor is substantially reduced.

Simplified, higher density and more reliable servers make the hyperscale all-flash datacenter more efficient than datacenters based on solid state disk and hard disk systems.
