Abstract: PROBLEM TO BE SOLVED: To properly hold a flex cable by turning up the flex cable inside a hard disk drive (HDD). SOLUTION: A bracket A70 and a bracket B80 are attached to a flex cable 60. The bracket A70 and the bracket B80 are made independent components, and a band 90 is installed. When the band 90 is used, the bracket A70 and the bracket B80 can be held by attaching the band 90, while the bracket A70 and the bracket B80 are made to overlap. By making the bracket A70 and the bracket B80 independent components, attaching and detaching are easy. Attaching and detaching can be clone in various steps of manufacturing and disassembling. A hook part and a support part can be also arranged on the band 90.

Abstract: PROBLEM TO BE SOLVED: To provide a ramp structure of a data storage device with which manufacture is facilitated and position shift in a load/unload ramp because of thermal expansion is made to be fewer as a whole. SOLUTION: The ramp structure has a first rigid supporting structure 52, a second rigid supporting structure 76 separated from the first rigid supporting structure, a bridge part 78 connecting the first rigid supporting structure with the second rigid supporting structure and a ramp unit 50 attached to the first rigid supporting structure. The rigid supporting structure has coefficient of thermal expansion that is selected so that space between a ramp and a disk is constant during change of temperature. The ramp unit 50 having accurate and stable seize can be formed by subjecting parts of the first rigid supporting structure 52 and the second rigid supporting structure sleeve 76 to insert molding by being inserted in a metallic mold for injection molding.

Abstract: PROBLEM TO BE SOLVED: To provide a hard disk drive(HDD) capable of preventing the damage on the part where a connector pin as an outer interface and a connector are mounted and to provide a mechanism which becomes a forcible guide at the time of mounting the hard disk drive(HDD). SOLUTION: There are some cases where a male connector 20 on the hard disk drive(HDD) 10 side is erroneously inserted into a female connector 60. For instance, the case where the former is inserted into the latter in the direction as shown by the arrow 1 can be cited. Therein, by disposing a cover 80 for the female connector, it is made unable to insert the male connector 20 into the female connector 60 unless the HDD 10 is moved along an insertion guiding surface 90. Also the cover 80 for the female connector is realized as a plate-shaped protruding part 82 which leaves a prescribed distance from a pin 22 of the male connector 20. The plate-shaped protruding part 82 is endowed with a satisfactory function when the protruding part 82 is disposed within the covering range so as to include at least an end part 68 of the female connector 60 with respect to both end parts 68 of the female connector 60.

CPC classification number: G11B25/043
Abstract: PROBLEM TO BE SOLVED: To provide a disk driving device case capable of effectively increasing the rigidity of the top cover.
SOLUTION: This disk driving device case 11 is provided with a case main body for housing the carriage 17 of a disk 15, and a top cover 13 for closing the opening of the case main body. In the top cover 13, a rib 30 is formed continuously around a specific area 31 in a full circumferential direction. The specific area 31 is positioned on the rotary shaft 19 of the disk 15. The rib 30 has a wide portion 30a and a narrow portion 30b. The narrow portion 30b is formed between a part corresponding to the top clamp 32 of the rotary shaft 19 and the end of the movable range 33 of a carriage 17.

Abstract: PROBLEM TO BE SOLVED: To provide a disk drive in which a head assembly can efficiently, reliably and highly accurately balanced, and to provide a head assembly or the like. SOLUTION: In a hard disk drive, a head assembly 13 to drive a magnetic head 33 for reading/writing data from/in a recording disk has a constitution such that the sleeve 21 of a pivot member 20 which swivelably supports the head assembly 13 is equipped with a flange part overhanging towards the circumferential side and flat surface parts 41A and 41B for adjusting the balance of the center of gravity of the head assembly 13 are formed on the circumferential surface of the flange part.

Abstract: PURPOSE:To facilitate production and to reduce a production cost by providing a locking piece to a frame having elasticity and fitting the locking piece in the groove of a cushoning member. CONSTITUTION:The vibration damping mounts 14A-14D are disposed on four corners on the back side of a base 2. A fitting obtained by working a groove 20A on one end of a cylindrical rubber 16A is welded on the mount 14A(-14D). Meanwhile, a frame 30 is constituted of a basic frame part 32 and frame parts 34 and 36 whose end part on an opposite side to the frame part 32 is a free end. In order to temporarily fix the frame 30 on the mounts 14A-14D, the locking pieces 38C and 38D are fitted in the grooves 20C and 20B of members 14C and 14D and then the locking pieces 38A and 38B are fitted in the grooves 20A and 20B of the members 14A and 14B. Thus, the frame 30 is temporarily fixed on the members 14A-14D. With such structure, nuts are not needed in order to fix the frame on the vibration damping mount. Therefore, the produc tion is facilitated and the production cost is reduced.
