Disc drive with head/disc assembly having sealed connectors

摘要

A disc drive includes a sealed head/disc assembly that has airtight electrical connections. The head/disc assembly has a first flexible circuit having one end that has electrical contacts which provide power to a spindle motor and another end which is terminated at a first connecter that is mounted to the base of a casing. A second flexible circuit routes electrical signals to a pivotally mounted actuator. The actuator carries read/write transducer heads and an actuator coil. One end of the second flexible circuit is coupled to the actuator and another end of the second flexible circuit is coupled to a second connector that is mounted to the base of the casing. A circuit board is mounted exterior to and along the base of the HDA casing. The circuit board includes third and fourth connectors which couple directly to the first and second connectors, respectively, when the board is mounted to the HDA.
