High-density disk drive having a cover portion which protects a light
weight head carriage from electromagnetic noise
摘要:
A high-density flexible disk drive includes a main electromagnetic shielding plate and an auxiliary electromagnetic shielding plate. The main electromagnetic shielding plate serves as a cover member for the disk drive, and protects the whole upper surface of a large-capacity flexible disk received in the disk drive, a carriage and a linear motor from electromagnetic noise coming toward the flexible disk, the carriage and the linear motor from the upper side of the disk drive. The auxiliary electromagnetic shielding is attached to the main electromagnetic shielding plate and is smaller than the main electromagnetic shielding plate. The auxiliary electromagnetic shielding plate is arranged and located so as to protect or shield a magnetic head from electromagnetic noise coming toward the magnetic head from the upper side of the disk drive.
