ABSTRACT:
A disk drive system and method employs sheet lift effect to suspend a data storage disk during high speed rotation. The system includes a data storage disk composed, at least partially, of an electrically conductive, nonmagnetic material and having at least one disk surface through which data communication may occur. The disk is rotated within an air-evacuated housing adjacent at least one magnet member. The interaction of the magnet member and the conductive, nonmagnetic material on the disk provides a sheet lift force suitable to suspend the disk during high speed rotation, such that the disk makes no physical contact with the housing or any structure fixed relative the housing. A read/write head assembly may also be provided with at least one magnet member which interacts with the conductive, nonmagnetic material on the disk to support the head assembly in a spaced relation to the disk surface.
