    Abstract: To easily confirm whether a breather filter is attached even after attaching a top cover on a base. Filter confirmation holes (21a) and (21b) besides a gas port (20) for circulating a gas between a breather filter (14) and the outside are formed in an area where the breather filter (14) is attached. At the time of a leak test to HDD 1, for example, a pressurized gas is supplied from a fresh air hole (20). If the breather filter (14) is not attached, the gas will leak from the filter confirmation holes (21a) and (21b). Therefore, it is detectable by measuring the pressure at the time of a leak test that the breather filter 14 is not attached. In addition, Figure (2) is a perspective view without a top cover.

    Abstract translation: 即使在将顶盖安装在底座上之后，也可以轻松确认是否连接了呼吸过滤器。 除了用于在通气过滤器（14）与外部之间循环气体的气体口（20）之外的过滤确认孔（21a）和（21b）形成在通气过滤器（14）附接的区域中。 例如，在对HDD 1进行泄漏测试时，从新鲜空气孔（20）供应加压气体。 如果未安装通气过滤器（14），则气体将从过滤器确认孔（21a）和（21b）泄漏。 因此，可以通过测量通气过滤器14未安装的泄漏测试时的压力来检测。 另外，图（2）是没有顶盖的透视图。

    Abstract: A disk drive has an internal breather filter that performs a filtration function while maintaining ventilation with an exterior of the drive. The filter circulates a gas between an interior and the exterior of its enclosure. The enclosure includes a first ventilation path for circulating the gas from the exterior to the filter, and a second ventilation path for circulating the gas from the filter to the exterior. In addition, a method of inspecting the filter and disk drive is disclosed. The method includes a compressing and decompressing step of compressing and decompressing the inside of the enclosure, a measuring step of measuring pressure in the enclosure, and a judging step of judging whether attachment of the filter is adequate on the basis of a value of the pressure measured.
