  • Wet rigid disk drive assembly with a conical spindle bearing
    Patent number: 6122143
    Abstract: The invention concerns a disk drive assembly in which one or more rotating rigid disks are enclosed in a "wet" operating environment in which a liquid lubricant is circulated from the surface of the rotating disks, through a wicking material within the disk drive assembly, and back to the head-disk interface. The wet environment supports the provision of open conical bearings in the spindle and actuator portions of the head-disk-actuator (HDA) of the disk drive assembly.
