    Abstract: A disc drive has a rotatable disc carried by a spindle motor and an actuator assembly with a read/write head. A base deck supports the spindle motor and the actuator assembly and defines a connector opening for transmitting electrical signals from the read/write head through the base deck to a printed circuit board attached to an exterior surface of the base deck. A bulkhead connector is adhesively affixed to the base deck to cover the connector opening. The bulkhead connector comprises a backing plate and a flex circuit bonded to the backing plate. The flex circuit extends across a top surface of the backing plate, wraps around one edge of the backing plate, and extends across a bottom surface of the backing plate.

    Abstract: A method for writing servo information to a data storage medium adapted for use in a data storage device wherein the medium is operably moved in ambient air at a nominal speed in data reading and writing relationship with a data transfer member. In one embodiment the method for writing comprises placing the medium adjacent a data transfer member in an enclosure containing a gaseous environment as a selected state; moving the medium to impart velocity to the gaseous environment which, in turn, impacts the data transfer member with forces flying the writing member at a first fly height from the medium; and subsequently introducing a gas having a density less than the gaseous environment into the enclosure, thereby responsively reducing the fly height of the writing member to a selected height less than the first fly height.

    Abstract: A method and apparatus is described for reducing and isolating actuator noise in disc drives. An isolation mount is provided between the disc-drive case and its external mounting assembly. A disc drive that includes an external mounting member, a disc case, and an actuator assembly mounted within the disc case. In some embodiments, the disc drive also includes at least one damper holding the disc case to the external mounting member that allows rotational movement of the disc case relative to the external mounting member in order to reduce the emission of sound from the disc case. Another aspect of the invention provides a disc drive that includes an external mounting member, a disc case, an actuator assembly mounted within the disc case, and at least one damper holding the disc case to the external mounting member, the damper including a softer part and a stiffer part, wherein the softer part acts primarily for relatively small movements of the disc case and the stiffer part acts primarily for relatively large movements of the disc case.

    Abstract: A rotary actuator assembly for positioning read/write heads in disk drive mass storage systems. The actuator assembly includes an actuator motor and one or more actuator arms secured thereto. The motor provides rotary motion of the arms, to move the heads. The stator magnet of the motor is an electromagnet wound on an arcuate core; a pair of elongate permanent magnets are attached to the rotor member, for coaction with the stator magnet. The rotor member has a U-shaped cross sectional area in a plane perpendicular to its axis of rotation; the permanent magnets are fixed to the outside, bottom corners of the U and the actuator arms are mounted across the open end of the U. The rotor is of a very small radius, to minimize inertia. The permanent magnets have a flat face facing the stator, with a channel running longitudinally down the middle, to minimize flux density variations in the permanent magnet-coil gap. The rotor balances the arm relative to the rotor's axis. The arms are of a substantially symmetrical tapered truss design, presenting low inertia; each is cantilevered to the rotor by one bolt which is passed through and pulls the arm against the rotors. Additionally, a spirol-type cylindrical spiral spring, received in a slot in the arm, prevents lateral slippage of the arm relative to the rotor. A pair of cantilevered leaf spring crash stops fixed to the stator decelerate the rotor at the ends of its range of travel.
