  • Patent number: 6775106
    Abstract: An improved E-block for positioning one or more transducer assemblies proximate one or more rotating storage disks of a disk drive is provided herein. The E-block includes an actuator hub and one or more actuator arms which cantilever away from the actuator hub for holding the transducer assemblies proximate the rotating storage disks. As provided herein, at least one of the actuator arms is a depopulated actuator arm which retains less than two transducer assemblies. Each depopulated actuator arm includes at least one, weighted segment integrally formed into the depopulated actuator arm. Further, each depopulated actuator arm has an arm thickness which is less than an arm thickness for a double head actuator arm. The weighted segment and the reduced arm thickness allow the depopulated actuator arm(s) to vibrate similar to a populated actuator arm(s). This allows the disk drive to be designed and tuned to improve fragility and resonance characteristics of the E-block.

  • Patent number: 6704168
    Abstract: An actuator latching mechanism for a disk drive device is provided. The latching mechanism includes a rotatable body portion, a rigid air vane portion and a latching arm. When a data storage disk of the disk drive is not being rotated, the latching mechanism maintains a transducer actuator assembly of the disk drive in a locked position by engaging the transducer actuator assembly in the latching arm. When the data storage disk is rotated, airflow is generated proximate to the surface of the disk, in the same direction in which the disk is rotated. The latching mechanism is disposed in a space between the edge of the data storage disk and a side wall of the housing so that the peripheral effects of the airflow exerts a force on the air vane portion, rotating the latching mechanism towards the side wall to release the actuator assembly from the latching arm. Once disk rotation stops, the air vane portion returns to its original position and the latching arm engages the actuator assembly in the locked position.
