发明名称 Method and apparatus for electromagnetic interference reduction in magnetic recording devices
摘要 In a magnetic recording/reproduction device, such as a disk drive one or more conductive elements is positioned in close proximity to a recording/reproduction head in order to absorb EMI generated by the head as it reads and/or writes data from/to magnetic media. The conductive element is connected through a low impedance path to an electrical sink, such as ground, for absorbed EMI. The conductive element thereby significantly reducing EMI in a manner analogous to the operation of a groundplane in a circuit board. In a disk drive implementation, the conductive element may be positioned on the opposite side of the disk from the head, on the same side of the disk as the head, or one or more conductive elements may be positioned on each side of the disk.
