ABSTRACT:
A passive non-contact magnetic latch for latching read/write heads of a disk drive over a landing area of the disk is disclosed. The magnet latch forms a magnetic circuit for capturing a latch tab within an air gap. Magnetic flux lines traverse the latch tab in a direction substantially perpendicular to a direction of movement of the latch tab.
