Abstract: A head support assembly for a disk drive is comprised of a head suspension assembly connected to an actuator arm at one end and supporting a head at the other end, wherein a projection is formed on a flexure closely fixed on a thin-plate load beam, said projection projecting toward a disk surface and having a smooth surface. The projection is formed at a region somewhat close to the head supporting end from the hinge portion of the load beam. When shock is applied to the disk drive, bending occurs around the hinge portion of the load beam. During such bending, the projection having a smooth round surface is caused to contact the disk, whereby the disk surface is prevented from being damaged.

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.

Abstract: A head support assembly for a disk drive is a head suspension assembly connected to an actuator arm at one end and supporting a head at the other end, wherein a projection (47) is formed on a flexure (14) closely fixed on a thin-plate load beam (12), the projection projecting toward a disk surface and having a smooth surface. The projection is formed at a region somewhat close to the head supporting end from the hinge portion of the load beam. When shock is applied to the disk drive, bending occurs around the hinge portion (45) of the load beam. During such bending, the projection having a smooth round surface is caused to contact the disk, whereby the disk surface is prevented from being damaged.

Abstract: The present invention purposes a hard disk drive having an enclosure 1 including disk construction members. The hard disk drive is configured so as to cover the enclosure 1 with an electric conductor sheet 2. In case of the present invention, by covering the enclosure 1 with the electric conductor sheet 2, ESD is absorbed by the electric conductor sheet even if ESD comes from any direction and thereby, ESD does not pass through the disk construction members stored in the enclosure 1. Therefore, it is possible to realize a structure not damaged due to ESD even if the structure is handled by a general end user.

Abstract: PURPOSE: To obtain a disc drive having a lock mechanism strong against strong impact by employing the lock mechanism in the horizontal and vertical directions for a recording medium. CONSTITUTION: When the rotation of a magnetic disc 3 decreases due to stoppage of a magnetic disc drive 1, an actuator arm 8 is shifted to a parking zone disposed on the inner circumferential side. When an iron piece 11 is attracted to a magnet 12, an arm 8 is shifted in the inner circumferential direction of recording medium 3 and eventually stopped. A lock mechanism comprising a solenoid coil 28 is movable up and down with respect to the recording medium 3 and when the arm 8 is shifted into the parking zone, the lock mechanism is shifted upward by means of the coil 28 and engages with the arm 8. The arm 8 is secured effectively even if a strong impact is applied externally in a short time under that state. Consequently, data on the medium 3 is protected against unexpected movement of the arm 8.

Abstract: PROBLEM TO BE SOLVED: To provide a plate-like apparatus, an apparatus with a built-in rotating body and a disk device which enable absorbing of shock from the outside, and moreover, easily performing loading. SOLUTION: Shocks from the outside are absorbed, and the deviation of axis, etc., of a magnetic disk 1b is prevented by setting bumpers 40A, 40B, 40C and 40D at the four corners of the disk device 10. At this time, at the two corner parts of the end part side of a guide groove formed on a base 12, pedestal surfaces 31A, 31B are formed on one side of the guide grooves, so that the plate-like bumpers 40A, 40B are set. In addition, on the remaining two corner parts, the plug-in bumpers 40C, 40D are set, and a label which covers one part of the plug-in bumpers may be stuck from above.

Abstract: PURPOSE: To eliminate the damage of a magnetic head, magnetic disk and to reduce in thickness of a magnetic disk apparatus by specifying the deflection of a suspension due to the impact. CONSTITUTION: If HDD receives an impact in the state that a magnetic disk 22 is retracted in a shipping zone, a suspension 34 having a magnetic head 36 at the free end is deflected. When the case that the lowermost suspension 34 is deflected is observed, the free end of the suspension 34 is brought into contact with a pin protrusion 50 to prevent the further displacement toward a base 12. The suspension 34 further deflected in this state is not deflected in primary mode (cantilever support mode), but deflected in a secondary mode of both ends support (both ends support mode), and the maximum displacement of the suspension 34 occurs at the intermediate part of the suspension 34. The displacing intermediate part is intruded into the groove 48, and the contact with the base 12 of the intermediate part of the suspension 34 is prevented by the grove 48.
