Abstract
A data storage device includes a base, a shaft that extends perpendicular from the base, and a head stack assembly (HSA) having a first end to which a head is coupled and a second end that is movably mounted on the shaft. The data storage device also includes either a first actuator assembly or a second actuator assembly. The first actuator assembly includes a first coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second coil-permanent magnet assembly that serves as a first elevator to linearly move the HSA along the shaft. The second actuator assembly includes a third coil-permanent magnet assembly that rotatably moves the HSA about the shaft, and a second elevator that linearly moves the HSA along the shaft and also moves a data storage device ramp in unison with the HSA.
