A hard disk drive includes a cover coupled to a base deck to create an enclosure. The hard disk drive further includes data-recording components and non-data-recording components positioned within the enclosure. At least one of the non-data-recording components includes a surface with a surface treatment that promotes condensation of water vapor.

The present disclosure relates to using solid state deposition to selectively and strategically manage one or more properties of one or more portions of a data storage device. Material deposited via solid-state deposition can be used to prepare a surface for subsequent treatment (e.g., welding), to join two or more substrates together, and/or to seal one or more joints or surfaces to control, e.g., the humidity in the interior of a data storage device. The present disclosure also involves related data storage devices.

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.

A computer program product, including a storage device storing computer readable program code executable by a processor to implement a method for corrosion protection of a tape drive based on a tape drive corrosion protection system that includes a tape drive, a temperature sensor, a heating entity, and a controller. Humidity information is determined via a humidity sensor. Temperature information, indicative of a temperature in or within the tape drive, is established via the temperature sensor. The temperature information is received at the controller. The heating entity is activated in a manner dependent on the temperature information established via the temperature sensor in order to prevent corrosion within the tape drive. Activating the heating entity is in response to a determination that the relative humidity is above a specified relative humidity threshold value and a temperature drop is above a specified temperature drop value within a specified period of time.

A hard disc drive includes a base deck, a cover welded to the base deck, and a voice coil motor. The voice coil motor includes a first voice coil motor assembly and a second voice coil motor assembly. Either one or both of the first and second voice coil motor assemblies can be welded to the base deck.

A magnetic disk device includes a case including a magnetic disk, a magnetic head configured to read or write data from or to the magnetic disk, an actuator configured to move the magnetic head, and a humidity sensor positioned within the case to measure a humidity in the case and output a measurement value; a control circuit configured to calculate a value of a voltage to be applied to the actuator based on a displacement amount of the magnetic head and the measurement value output from the sensor, and output the calculated value; and a servo controller configured to control the actuator by applying the voltage to the actuator according to the value output by the control circuit.

A disk drive enclosure includes a cover having a peripheral shape conforming to that of a base of the disk drive enclosure. A formed-in-place gasket is on an inner surface of the cover and corresponds to a shape of a mating edge of the base. The formed-in-place gasket forms a seal between the cover and the mating edge of the base. A stop member is located along an inner periphery of the formed-place-gasket and in immediate proximity to the formed-in-place gasket.

A data storage library system includes at least one data storage library comprising at least one library frame and at least one environmental conditioning unit, the at least one environmental conditioning unit configured to control one or more environmental conditions within the at least one library frame. The system further includes at least one access door for providing access to an interior portion of the data storage library, a library controller, and at least one warning indicator associated with the data storage library and in electronic communication with the library controller. The at least one warning indicator is configured to provide an indication to an operator when the conditions within the data storage library are such that the at least one access door may be opened and when the conditions within the data storage library are such that the access door should not be opened.
