摘要： 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.

摘要： 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.

摘要： 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.

摘要： An interface to make interconnections between the interior and exterior of a sealed enclosure may include a flat connector (FC). The FC may comprise at least one layer of a substantially planar substrate. Each substrate layer may include metallization for conducting signals between contacts on an interior-facing surface and contacts on an exterior-facing surface. In an enclosure with an aperture for passing electrical conductors, the FC may be configured to seal the aperture to inhibit the escape of a low density gas, such as helium, for a long period of time. In one embodiment, the FC may include metallization configured to minimize helium leakage. As such, the FC may conduct electrical signals into and out of the sealed enclosure. Such signals may include, for example, power, control, and data signals for operating devices housed within the enclosure.

摘要： A method of controlling an actuator in a disc drive to perform a seek operation prior to a read operation is disclosed. A radial distance between the initial track and the target track is determined. A rotational distance between the initial head rotational position and the target rotational position is also determined. The magnitude of the performance benefit to be gained by reading pre-fetch and post-fetch data is estimated. Then a seek velocity profile is selected based on the radial distance, the rotational distance and the estimated magnitude of the performance benefit that would be gained by reading pre-fetch and post-fetch data. The actuator then is controlled using the selected seek profile. A disc drive for implementing this method is also provided.
