  • Vibration damped flexible circuit for use in a hard disk drive
    Patent number: 7414813
    Abstract: A method and apparatus for damping vibration in a flexible cable for use in a magnetic disk drive apparatus. The vibration damping mitigates resonant oscillation of the flexible cable which would otherwise cause tracking errors by forcing the actuator of the away from the desired data track on a magnetic disk. A layer vibration damping material and one or more electrical leads are enclosed within a surrounding electrical insulator, the damping material being completely enclosed, while the leads have selected portions exposed to allow electrical connection devices.
    Type: Grant

  • Actuator arm design for reducing power consumption in a disk drive data storage device
    Patent number: 6950286
    Abstract: A hard disk drive utilizes an actuator arm design that significantly reduces air flow drag within the drive. The leading and trailing edges of the arm are shaped to reduce their coefficient of air flow drag in order to reduce the running current and seeking current of the disk drive during operation. As a result, the disk drive consumes less power and, thus, produces less heat which must be dissipated. The spindle motor design is reconfigured at a lower torque constant, thereby lowering the overall cost of the device.
