A hard disk drive comprises a sensor configured to detect a mixing ratio within the hard disk drive and a membrane electrode assembly. The membrane electrode assembly comprises a gas flow path that couples an inside of the hard disk drive to an outside of the hard disk drive, and the gas flow path includes a cathode and anode that electrolytically remove water vapor from the inside of the hard disk drive. The drive further includes an energy source coupled to the membrane electrode assembly and a controller coupled to the sensor and the energy source. The controller is configured to activate the energy source in response to the sensor detecting a mixing ratio greater than a threshold mixing ratio and to deactivate the energy source in response to the sensor detecting a mixing ratio less than the threshold mixing ratio.

The present disclosure relates to dehumidifying devices and data storage devices that include a dehumidifying device. A dehumidifying device can include first and second electrical terminals that are located on the same side of the dehumidifying device to easily couple the terminals to electrical connections external to the data storage device such as a printed circuit board assembly.

Dehumidifying devices, and data storage devices having one or more dehumidifying devices

A hard disk drive mounting assembly that includes a disk drive assembly having a base structure that includes a screw hole and a damping insert at least partially surrounding the screw hole. The disk drive assembly further includes a threaded insert positioned in the screw hole of the damping insert.

Mounting structure for hard disk drives

A breather filter for reducing water in a data storage device housing includes an outer layer, an inner layer, and an intermediary layer positioned between the inner and outer layers. The outer layer includes an outer layer of hydrophilic material. The inner layer includes at least one of an inner layer of hydrophobic material and an inner layer of hydrophilic material. The intermediary layer includes a water adsorbing material, and fibers that promote water permeation from the inner layer to the outer layer.

Data storage device filter

A disk drive including multiple magnetic recording disks and at least one read/write head, wherein the disk drive includes a rotatable center block having a vertical axis and a mounting member, a first motor attached to the center block for rotating the center block about the vertical axis, a vertical threaded rod positioned in the mounting member, a second motor moveable along the vertical threaded rod, at least one head suspension arm extending outwardly from the second motor, and at least one read/write head mounted to a distal end of one of the arms. The disk drive further includes multiple disks in a stack, wherein at least one of the arms is vertically moveable along the vertical threaded rod by the second motor to position the at least one read/write head in a position to access data on one of the disk surfaces of the plurality of disks.

Disk drive having multiple disks accessible by a reduced number of read/write heads

A data storage device that includes a housing and at least one data storage medium within the housing. The data storage device further includes an anti-shock system having at least one piezoelectric layer on a portion of the housing and at least one element electrically coupled to the at least one piezoelectric layer. The at least one element provides a deflection control signal to the at least one piezoelectric layer.

Anti-shock system for a data storage device

Method and apparatus for securing a disc stack to a spindle motor hub. In some embodiments, a disc clamp assembly includes a spring clamp with an annular contact portion which contactingly engages a disc stack and a central aperture through which a hub projection of the spindle motor hub extends. A plurality of interlocking semi-annular shim segments interlock together to form a continuous retention ring assembly which wedges between the spring clamp and a shoulder surface of the spindle motor hub.
