摘要： Data is written to a hard disk drive using shingled writing principles, i.e., each data track is partially overwritten when an immediately contiguous data track is written. Two or more contiguous data tracks establish a band, and a band may store data from one and only one file, such as an AV file.

摘要翻译： 数据被写入硬盘驱动器，使用着色的写入原理，即当立即连续的数据磁道被写入时，每个数据磁道被部分覆盖。 两个或更多个连续的数据轨道建立一个频带，并且一个频带可以存储来自一个文件，例如AV文件的一个文件的数据。

摘要： An embodiment of the invention is a head for perpendicular recording that has a trailing shield and side shields that are connected to the return pole piece by two studs of ferromagnetic material. The studs extend parallel to the track direction and are located a sufficient distance away from the main pole piece to reduce the flux flow from the main pole piece to the studs. Optionally the studs can be recessed behind the air-bearing surface. The preferred embodiment of the invention is a magnetic transducer with separated read and write heads for perpendicular recording.
