    Abstract: A data storage device includes a data storage disc, an arm, a head, a rotary actuator, and an elevator. The disc has a read/write surface defining an x-y plane. The arm includes a load beam. The head is supported by the load beam, and the head is configured to interact with the read/write surface. The rotary actuator is configured to move a first portion of the arm about a first pivot axis in the x-y plane. The elevator is configured to move the arm in a z direction relative to a vertical surface and is configured to frictionally engage the vertical surface to hold the arm at a z direction position while allowing the rotary actuator to move the first portion of the arm about the first pivot axis. In another aspect, an apparatus includes a stack block, first and second clamp arm assemblies, and first and second piezoelectric actuators.

    Abstract: A data storage system include a disk drive having a rotating ramp assembly that may be moved between an engaged and disengaged position. The rotating ramp assembly may include a ramp extension that is not disposed in overlapping relation to a data storage disk location in the drive when in the disengaged position. However, in the engaged position, the ramp extension may overhang a portion of the data storage disk location. In turn, the head extension may include a ramp surface that allows a head assembly to move to a head parking surface when the rotating ramp assembly is in the engaged position. IN turn, the rotating ramp assembly may be rotated while maintaining the head assembly on the head parking surface, which may be arcuate and extend about at least a portion of the rotating ramp assembly.

    Abstract: A data storage device includes a ramp configured to support at least one head in the data storage device, and a movement mechanism coupled to the ramp and configured to move the ramp from a first position to a second position by at least one of expansion or contraction of at least a portion of the movement mechanism. The data storage device further includes a ramp motion control module operably coupled to the movement mechanism. The ramp motion control module is configured to provide the movement mechanism with a first control signal that causes the movement mechanism to move the ramp from the first position to the second position. The data storage device additionally includes a latch configured to hold the ramp.

    Abstract: A data storage device includes a stack of a plurality of disks, first and second arms, first and second heads, first and second linear drivers and an elevator. Each of the plurality of disks includes a read/write surface. The first arm has a first head end that is movable relative to the stack. The first head is configured to interact with a selected one of the read/write surfaces. The first linear driver is configured to move the first arm along a first straight line in a x-y plane defined by the one of the read/write surfaces. The elevator is configured to move the first arm in a z direction. The second arm has a second head end that is movable relative to the stack and supports the second head. The second linear driver is configured to move the second arm along a second straight line in the x-y plane.
