    Abstract: According to one embodiment, a host bus adapter (HBA) is disclosed. The HBA includes one or more link layer engines, one or more ports, each of the one or more ports associated with one of the one or more link layer engines and token passing logic having a shift register associated with each of the one or more link layer engines. A first link layer engine enables a first storage device coupled to an associated port to spin-up whenever the first link layer engine detects that a first shift register has a first value.

    Abstract: A disk drive unit for a disk (D), comprises a turntable (2) for a disk (D) which is rotatably supported by the base and drivable by a motor (6) including a stator (7) mounted on the base and a rotor (5) connected to the turntable. A clamping mechanism (9, 11) is provided to hold the disk firmly on the turntable. A suction mechanism (9, 10) effects an axial attraction force between the stator and the rotor. The clamping and suction mechanisms (9, 10, 11) include a single annular magnet (9) attached to the turntable (2) on a side thereof facing the stator (7). As a result, the magnet is protected against corrosion and foreign particles and there is no need for a back yoke to create sufficient attraction force. This leads to an easily balanced turntable which can be produced in a cost-effective manner.

    Abstract: The present invention relates to a turntable for a drive for interchangeable storage media in disc form. According to the invention, in the case of a turntable for a drive for storage media in disc form, with a bore for receiving a motor shaft of a drive motor, the diameter of the bore is greater, at least in a partial region of the bore, than the diameter of the motor shaft, so that there is a gap between the wall of the bore and the motor shaft, and the inclination and/or the position of the turntable can be set in relation to the axis of rotation of the motor shaft.

    Abstract: A fluid bearing design is provided which according to one aspect includes a shaft defining together with a surrounding sleeve an asymmetric journal bearing, and a thrust bearing at or near an end of the shaft towards which the asymmetric journal bearing is pumping, with that end of the shaft being closed off. The journal bearing asymmetry establishes a hydraulic pressure toward the closed end of the shaft. This pressure provides an axial thrust to set the bearing gap for the conical bearing. The conical bearing itself is a relatively balanced bearing, although it may have a bias pumping toward the shaft and the journal bearing. A pressure closed equalization path from the journal bearing through the conical bearing to the end of the shaft may be established to maintain a constant hydraulic force across the conical bearing, and which may also prevent any asymmetry in the conical bearing from affecting the net thrust force acting upon the end of the shaft where the conical bearing is located. Alternatively, in a fluid dynamic bearing design comprising a shaft and a thrust plate at or near an end of the shaft, asymmetry is again established along the journal bearing to establish a pressure gradient directed toward the thrust bearing.
