Abstract
A data storage device is provided having at least one disk rotated by a spindle motor and at least one actuator arm assembly rotatable in response to a voice coil motor about a pivot point for moving a magnetic head on an actuator arm for writing data onto the tracks of the disk and reading the data recorded on the tracks of the disk. The data storage device comprises a first plate, the spindle motor being secured to the first plate and a second plate secured to the first plate, the actuator arm assembly being secured to the second plate. A method for mounting at least one actuator assembly within a data storage device is also provided.
