  • Inertial latching mechanism for disk drive actuator
    Patent number: 7242555
    Abstract: The invention prevents the deterioration of the read/write performance of a hard disk drive due to the interference between an inertial latching mechanism and an actuator when a head slider holding a magnetic head is located at a read/write position. A latching arm 22 provided with a projection 23 and included in an inertial latching mechanism 20, and a part 161 of a coil holding arm 16a included in an actuator are formed in shapes such that the latching arm 22 provided with the projection 23 does not interfere with the coil holding arm 16a having the part 161 when a head slider mounted on the actuator is located at a read/write position on a magnetic disk.

  • Flex cable, head suspension assembly, and hard disk drive
    Patent number: 6480362
    Abstract: A flexible cable assembly (FCA) has a flexible cable, first and second brackets attached to the flexible cable, and a band for holding the first and second brackets while the flexible cable is folded back and the first and second brackets overlap. The band is detachably mounted to the first and second brackets to facilitate efficient manufacturing and disassembly methods. The FCA may be implemented at various manufacturing stages including the head suspension assembly (HSA) or the entire hard disk drive (HDD) assembly.
