With Operational Mode-varying Means Patents (Class 335/117)
  • Patent number: 5541790
    Abstract: A single-point magnetic contact latch assembly for "parking" a read/write head of a memory storage device over a data-free landing zone during off-power conditions has one or more permanent magnets, a core having a curvilinear shape on one end and an annular flange formed on the opposing end, and a casing, having an open end and a partially closed end, covering the magnet(s). The core is disposed adjacent the magnet(s) and lies within the flux paths thereof. The casing covers the core and magnet(s) so that the curvilinear end of the core extends through the partially open end of the casing. The casing abuts an outer periphery surface of the flange with a press-fit so that the casing is outwardly radially deformed at the point of abutment securely anchoring the casing, and magnet(s) in position relative to the core.
