摘要： A disk drive includes, on a base (5), at least one recording disk (8D) rotated by a spindle motor (8), a carriage (1) equipped with heads (7) for executing read/write operations with the recording disk and a voice coil motor (9) for driving the carriage, the carriage including an arm portion (11) for mounting the heads at a distal end thereof, a main body (13) equipped with a rotary shaft (12) and a rotor portion (14) serving as the rotor of the voice coil motor (9). The carriage structure is capable of reducing noise and accomplishing a high transfer rate. A control IC (121) in the form of a bare chip is packaged to a connection portion of the flexible circuit board (2) and the carriage by a flip packaging method, and other chip components are packaged by a surface packaging technology. The space at which the head IC, the servo IC and the peripheral circuits are disposed integratedly can be secured at the connection portion of the flexible circuit board with the carriage. Therefore, the noise at the time of read/write by the heads can be reduced and a transfer rate can be improved while heat radiation by the components can be taken into consideration.

摘要： A method and apparatus for sensing vibration in a flex circuit (106) located between a rotary actuator (100) and electronics within a disk drive. Specifically, the apparatus contains a strain gauge (302/408) attached to or embedded within the flex circuit (300/400). The resistivity of the strain gauge varies in response to vibrations on the cable. This resistance variation can be transformed into electrical signals that are used by a servo system to move the actuator assembly in compensatory motion that effectively cancels any off-track motion cuased by the vibrations.

The carriage structure is capable of reducing noise and accomplishing a high transfer rate. According to a first embodiment, an anchor member (3) comprising a flat sheet portion (30) and an extension portion (31) and made of a sheet metal is disposed on a flat surface portion (15) of the side surface of the carriage main body, and a flexible circuit board (2) is wound on the anchor member and is, in this state, connected to the carriage. Therefore, the package area on the carriage side can be increased. According to a second embodiment, a control IC (121, 122) of a bare chip is packaged to a connection portion of the flexible circuit board (2) and the carriage by a flip packaging method, and other chip components are packaged by a surface packaging technology. According to the first and second embodiments, the space at which the head IC, the servo IC and the peripheral circuits are disposed integratedly can be secured at the connection portion of the flexible circuit board with the carriage. Therefore, the noise at the time of read/write by the heads can be reduced and a transfer rate can be improved while heat radiation by the components can be taken into consideration.

摘要： A member securing electrical conductors coupled to a read/write head in a storage device over termination pads of an electrical flex circuit. Generally, the storage device includes an actuator having at least one actuator arm securing the read/write head, and the apparatus is coupled to the actuator arm. The apparatus may comprise a member having a first end and a second end, the first end being coupled to the arm and the second end positioning the conductors over conductive pads of the flex circuit, with the second end including a window securing the conductors in fixed positions over the conductive pads of the flex circuit. In another arrangement, the second end comprises a solderless coupling assembly electrically connected to the conductors, wherein the conductive pads of the flex circuit are arranged to electrically couple to the solderless coupling assembly.

摘要： An FPC holding mechanism (140) of an actuator assembly of a hard disk drive (HDD) includes an FPC holder (142) protruding from an arm-mold of the actuator assembly, and an FPC clip (152) that is mounted to the FPC holder so as to be rotatable relative to the FPC holder. The FPC holder defines a guide groove (146) into which the FPC is inserted and a first side support plate (144) facing one side surface of the FPC. The FPC clip includes a second side support plate (154) juxtaposed with the first side support plate and facing the other side surface of the FPC, and at least two clip arms (155,157) extending in a horizontal direction over upper and lower edges of the FPC, respectively. At least one of the clip arms (155) has a hook (155a) that is hooked onto the first side support plate. The FPC holding mechanism thus prevents a portion of the FPC from moving in vertical and horizontal directions.

摘要： A flexible printed circuit board (150A-150H) has a flexible dynamic region (151), and relatively rigid static regions (152,153) between which the dynamic region (151) extends. Portions of a base layer (161), a conductive layer (165) extending on the base layer (161), and a cover layer (162) covering the conductive layer (165) make up the dynamic region (151). Extensions of the base layer (161), the conductive layer (165), and the cover layer (162), and portions of a metal layer (180) to which the base layer (161) is attached make up each of the static regions (152,153). The metal layer (180) enhances the rigidity of the flexible printed circuit board (150A-H) at the static regions (152,153). The metal layer (180) also has rounded corners (190A-D,192A-D) at sides of each of the boundaries (i,ii) between the dynamic region (151) and each of the static regions (152, 153) to minimize stress concentrations at the boundaries (i,ii). The conductive layer (165) is made up of real traces (166) through which electrical signals are transmitted, and dummy traces (167A). The dummy traces (167A) are disposed outwardly of the real traces (166) to prevent the flexible printed circuit board (150A-H) from cracking at the boundaries (i,ii) between the dynamic region (151) and each of the static regions (152,153). In a hard disk drive (HDD) the flexible printed circuit board (150A-F) electrically connects a head stack assembly (HSA) and a main circuit board.
