US07782574B1 Magnetic heads disk drives and methods with thicker read shield structures for reduced stray field sensitivity 有权
磁头磁盘驱动器和具有较厚读取屏蔽结构的方法，以减少杂散场灵敏度

Magnetic heads disk drives and methods with thicker read shield structures for reduced stray field sensitivity
Abstract:
A head of a disk drive comprises a read element, a top read shield, a bottom read shield, a stray field shield, and an exchange decoupling layer. The read element allows for reading magnetic fields from a recording medium. The top read shield, the bottom read shield, and the stray field shield allow for at least partially shielding the read element from stray magnetic fields. The exchange decoupling layer allows for at least partially providing exchange decoupling of the stray field shield and the bottom read shield. The read element is located at least partially between the top read shield and the bottom read shield. The bottom read shield is located at least partially between the stray field shield and the top read shield, and the exchange decoupling layer is located at least partially between the stray field shield and the bottom read shield.
Abstract(Chinese):

磁盘驱动器的磁头包括读取元件，顶部读取屏蔽，底部读取屏蔽，杂散磁场屏蔽和交换去耦合层。 读取元件允许从记录介质读取磁场。 顶部读取屏蔽层，底部读取屏蔽层和杂散场屏蔽层允许至少部分屏蔽读取元件免受杂散磁场的影响。 交换去耦层允许至少部分地提供杂散场屏蔽和底部读取屏蔽的交换去耦。 读取元件至少部分地位于顶部读取屏蔽和底部读取屏蔽之间。 底部读取屏蔽至少部分地位于杂散场屏蔽和顶部读取屏蔽之间，并且交换去耦层至少部分地位于杂散场屏蔽和底部读取屏蔽之间。
