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.

Abstract: It has been discovered that the cavity of data storage devices may be temporarily sealed to inhibit loss of gasses from the cavity by use of a sealing solution comprising a sealing component that is in contact with the gasket of the device, so that the gasket and sealing solution, together with the structural cover and base deck of the device, temporarily seals the cavity. The sealing solution comprises a sealing component having molecular weight of from about 1000 to about 30,000 Daltons.
