摘要： In a print head comprising a plurality of magnetic circuits each of which comprises an armature supported by a spring, a permanent magnet for biasing the armature in one direction, and an electromagnet which can be energized so as to cancel the biasing force of the permanent magnet, so that a print wire fixed to the armature may be driven by energizing the electromagnet and thereby driving the armature with the restoring force of the spring. The cross-sectional areas of the paths of magnetic flux between neighboring electromagnet circuits are made uneven. This can be achieved by providing base portions which are common to two electromagnet core portions. Thereby, the print pressure of all the print wires is made uniform and an increase in printing speed and improved print quality can be achieved at the same time.

摘要： A suspension for disc drive having a micro actuator mechanism comprises a base plate, a connecting plate having a hinge portion thinner than the base plate, a load beam provided with a flexure, a pair of actuator elements such as PZT, etc. The micro actuator mechanism includes a pivot portion formed between a pair of slits and support walls formed on the connecting plate. The actuator elements are provided individually on the opposite sides of the pivot portion. Each support wall is a bent portion that is formed by raising an edge portion of the connecting plate in the thickness direction of the main portion of the connecting plate.
