  • Load beam attachment to actuator arm
    Patent number: 6865058
    Abstract: An actuator assembly includes a rotatable actuator arm mounted on the base of a disc drive. The actuator arm includes a metallic member seated on a non-metallic body. A proximal end of a load beam is mounted on the actuator arm and a distal end of the load beam supports a head. The actuator assembly also includes a connection between the metallic member and the load beam that secures the load beam to the actuator arm.
    Type: Grant

  • Fiber reinforced laminate actuator arm for disc drives
    Patent number: 6678121
    Abstract: An actuator arm for a disc drive data storage device has an upper outer surface in a first plane, a lower outer surface in a second plane substantially parallel to the first plane, a peripheral outer surface substantially perpendicular to the first and second planes, and a voice coil embedded within the outer surfaces of the actuator arm. The actuator arm is used in a disc drive containing one or more data storage discs and preferably has a pre-amplifier embedded within the outer surfaces of the actuator arm as well as conductors preferably between the read/write head and the pre-amplifier within the outer surfaces of the actuator arm.

  • Disc drive with converging filter inlet for faster cleanup times
    Patent number: 6594108
    Abstract: An inlet to a disc drive's filter chamber is tapered to converge along most or all of its length so as to reduce drag and increase inflow volume and velocity. This accelerates the removal of particles from the disc drive's sealed chamber, reducing the likelihood of particle-induced data transfer errors or media damage.

  • Apparatus for displaying new information on a cathode ray tube display and rolling over previously displayed lines
    Patent number: 4068225
    Abstract: A communications terminal having a video output wherein new data is displayed on the bottom line of the CRT and each line of previously displayed data is moved up one line. Logic internal to the terminal increments the address of the storage locations within a memory to accomplish this. The new data being displayed replaced the oldest data stored in the memory.
