According to one embodiment, a disk device includes a housing, magnetic disks in the housing, and a printed circuit board attached to an outer surface of a bottom wall of the housing. The housing includes a base including a bottom wall and a side wall, and at least two base-side positioning portions provided on the bottom wall in a region overlapping the side wall. The printed circuit board includes at least two board-side positioning portions each engaged with the base-side positioning portion. One of the base-side positioning portion and the board-side positioning portion includes a pin extending substantially perpendicular to the bottom wall, and another includes a hole into which the pin is fitted.

Disk device

According to one embodiment, a disk device includes a housing including a bottom wall including a protrusion with a first surface, a recording medium arranged in the housing, a printed circuit board attached to the bottom wall, an electronic component mounted on the printed circuit board and including a second surface facing the first surface, and a radiation sheet including a third surface which is contact with the first surface, and a fourth surface which is in contact with the second surface. An area of the first surface is less than an area of the third surface of the radiation sheet, or an area of the second surface is less than an area of the fourth surface of the radiation sheet.

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.

Magnetic disk device

According to one embodiment, a disk drive includes a housing, a disk recording medium in the housing, a drive motor, a head, a carriage configured to support the head for movement, and a flow regulation member between the recording medium and a sidewall of the housing, except for a moving region for the carriage. The flow regulation member includes a shroud member, which is located substantially flush the recording medium and adjacently faces the outer peripheral edge of the recording medium, and a plurality of fins protruding from the shroud member and configured individually to guide an airflow passing along a surface of the recording medium toward the outer periphery of the shroud member and prevent a backflow toward a center of the recording medium.

Disk drive

A suspension device including a flexure with conductors is provided with an anti-ESD section. The anti-ESD section includes a metal plate, a insulating layer, a first electrically conductive member formed of a pair of read conductors, a second electrically conductive member formed of a pair of write conductors, a heater conductor, semiconductive layers, etc. The semiconductive layers are grounded to the metal plate and electrically isolated from one another by an insulating portion.
