    Patent number: 8619388
    Abstract: A fluid dynamic bearing with an immiscible fluid barrier deposited on the bearing oil is disclosed. One embodiment provides the fluid dynamic bearing having a seal gap to define a seal cavity. The seal cavity is filled with the bearing oil for lubricating the fluid dynamic bearing. The immiscible fluid is disposed on the bearing oil to prevent the bearing oil from evaporating from the seal cavity. In one embodiment, the immiscible fluid is insoluble in the bearing oil.

  • Disk drive having an insert with a channel for directing air flow to a rotary actuator voicecoil
    Patent number: 5956203
    Abstract: A data storage device for a computer system, such as a hard disk drive (HDD), provides means for channeling air flow from the spinning disks to other components within the HDD enclosure that require cooling, particularly a voice coil motor having a coil which is used to move an actuator assembly. Channeling may be provided by forming a slot or gap in the disk cavity wall, or by providing an insert part which has a channel formed therein that directs air flow to the VCM coil.
