Abstract
A magnetic disk device includes a casing having a box-like base that has a bottom wall and a cover that has a first surface facing the bottom wall, a magnetic disk provided in the casing, a head configured to write data to the magnetic disk and to read data from the magnetic disk, an actuator assembly that supports the head in the casing, a conductive container on the first surface of the cover, and a conductive body in contact with the conductive container and the cover.
Claims18
A magnetic disk device comprising:
- a casing having a box-like base that has a bottom wall and a cover that has a first surface facing the bottom wall;
