Abstract: PROBLEM TO BE SOLVED: To provide an inertia latching mechanism with which the erection of a pin for oscillation of an inertia lever can be omitted. SOLUTION: This disk driver comprises a lever body 22 which oscillates the inertia lever 21 used for the inertia latching mechanism by the inertia of an impact when this impact is applied to the inertia lever, a stator 24 which is fixed to a casing of the disk driver and a leaf spring member 23 which connects the lever body 22 and the stator 24 and permits the oscillation of the lever body 22.

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: PROBLEM TO BE SOLVED: To provide a clamp which can decrease a distortion generated in a magnetic disk. SOLUTION: The top clamp 3 is provided with an elastic part 3a which is made up of a circular sheet spring body and generates an elastic force and a centering hole 3c which is extendedly disposed on a pressurizing part 3b. Therein, a coating layer 3d with FEP (Fluorinated Ethylene Propylene Copolymer) formed on the surface facing the magnetic disk 1 of the pressurizing part 3b is disposed. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a hard disk device which is capable of straightening air flow between disks and suppressing vibrations of the disks and actuators, and an air flow straightening blade used in the device. SOLUTION: The hard disk device 1 of this invention consists of a housing 2, the plural disks 3 which are housed rotatably in the state of being stacked in the housing 2 and the actuators 5 which are housed movably with respect to the surface of the disks 3 in the housing 2 and have data read/write head 4 at the tip thereof. In the hard disk device 1, the air flow straightening blades 6 which are streamlined in cross section are disposed while leaving a specified interval just behind the down stream side in rotational direction of the disks with respect to the moving position of the head 4 on the disks 3. Further, in order to complete the hard disk device 1, the air flow straightening blades 6, which are constituted by erecting plural plate-like bodies having streamlined cross section on a substrate 11 in such a manner that the streamlined cross section becomes parallel with the substrate 11, are utilized.
