ABSTRACT:
An architecture for a low profile disk drive device wherein a lower surface of an information bearing disk abutting an upper surface of a spindle motor is not accessed by a read/write head for data storage or retrieval. The disk is used as a magnetic shield to protect reading and writing from an upper surface of the disk, The architecture facilitates lower profile construction because the spindle motor can be made with a larger diameter and thinner height. Memory capacity is not sacrificed because a greater portion of the remaining disk surfaces is utilized.
