Computer hard drive has read-write coils mounted on a separate eccentric read disk that rotates over the surface of a data disk

摘要

Computer hard drive has read-write coils integrated in a rotating read disk that is separate from the data disk. The rotation axis of the read-write disk is eccentric to the data disk, while the disk surfaces overlap as the disk surfaces are rotated over each other at high speed. Read-write coils can be placed in pairs around the circumference of the read disk.
