用于减少杂散场的穿透和影响的磁盘驱动器的屏蔽外壳

Shielded enclosure of a disc drive for reducing penetration and influence of stray fields
摘要：
The present invention includes a data storage system. The data storage system includes an enclosure and at least one perpendicular recording device positioned within the enclosure and in communication with a recording medium. The recording medium includes a layer of magnetic material that has a permeability that is substantially similar to a permeability of a magnetic material in the recording device. The data storage system also includes a soft magnetic material included in the enclosure for shielding magnetic stray fields from the perpendicular recording device. The soft magnetic material has a permeability that is at least as great as approximately the permeability of the layer of magnetic material of the recording medium.
摘要（中）：

本发明包括数据存储系统。 数据存储系统包括外壳和位于外壳内并与记录介质通信的至少一个垂直记录装置。 记录介质包括具有与记录装置中的磁性材料的磁导率基本相似的磁导率的磁性材料层。 数据存储系统还包括用于屏蔽来自垂直记录装置的磁性杂散场的外壳中的软磁材料。 软磁性材料的磁导率至少与记录介质的磁性材料层的磁导率大致相同。
