[0048] According to the first embodiment, the upper surface of the cover 3A that is in contact with the atmosphere has the ventilation hole 33 formed in the vicinity of the edge of the cover 3A and constituting a through hole communicating between the inside and the outside of the magnetic disk device 10A. An annular filter-accommodating groove 36 having a uniform depth formed around the ventilation hole 33, an air passage formed through the cover 3A at a position overlapping the ventilation hole 33 formed through the upper surface and the lower surface of the base 6 37, and the ventilation groove 38 used to ensure the communication between the air channel 37 and the filter groove 36. Reference numeral 35 designates a hole for fastening the rotational shaft of the spindle motor 65 and reference numeral 39 designates an overflow hole of the magnetic circuit of the transmission 64 . The overflow hole 39 formed in the cover 3A has an upper surface generally covered with an adhesi...

A disk device is disclosed in which an air inlet to an air passage for ventilation between inside and outside of the disk device is secured even when the upper or side surface of the housing of the disk device is closed, while at the same time suppressing the noises and vibrations originating from the disk device. A spindle motor for carrying at least a recording disk and an actuator for driving a carriage having a head for accessing the disk are mounted on the base of the housing. A cover is mounted on the base through a gasket thereby to hermetically seal the interior of the disk device. A ventilation structure is formed in the cover. This ventilation structure includes an air passage formed in the neighborhood of an edge of the cover, a filter-accommodating recess formed around the air passage, an air filter arranged in the filter-accommodating recess, an air passage formed through the base outside of the gasket of the disk device, a ventilation groove formed in the upper surface of the cover for securing communication between the filter-accommodating recess and the air passage, and a sealing member for covering the air passage on the upper surface of the cover.
Description
technical field [0001] The present invention relates to a disk device, or more particularly to a disk device having high sound insulation performance for preventing leakage of noise generated in the disk device, which includes a device for allowing air to flow in the device under any environment in which the device is used in a computer system. Ventilated structure for flow between inside and outside. Background technique [0002] In recent years, disk devices such as magnetic disk devices and optical disk devices have been used as storage devices for computers. These devices are used with computers in various environments, so it is necessary to adjust the difference in air pressure between the inside and outside of the device caused by changes in the environment or air pressure. For this purpose, ventilation holes (also referred to as vent holes) are usually formed in the cover of the disk device. [0003] In the case of keeping the non-running disk device in a normal env...
