摘要： An assembly for use in providing EMI shielding for a circuit card. The assembly comprises a circuit card; a fastener; and, a shielding apparatus. The shielding apparatus comprises: a body providing EMI shielding and includes an attaching portion extending therefrom, wherein the attaching portion has a segment at a proximal end portion thereof which blocks an opening in the body for controlling EMI leakage and positions the attaching portion so that a fastener can fasten the attaching portion to a circuit card such that a first fastener end portion is engageable in juxtaposed relationship with a first card surface and a second fastener end portion terminates so as not to extend generally beyond a predetermined distance from a second card surface of the card.

摘要： An actuator of a high performance tape drive for coarse and fine positioning of a read/write head incorporates at least a pair of cantilevered beam springs which support a read/write head for controlled movement relative to a moving storage tape. The beam springs and head are controlled by a rocker member that transmits movement of a voice coil to the head for servo controlled fine positioning of the head relative to the data track of the tape.

摘要： A tape drive system is described which incorporates a zero clearance bearing for use on a lead screw positioning system having a structure which inherently flexes or closes onto the external surfaces of the lead screw to cause a precise positioning of the lead screw axis relative to a bearing and a bearing support for the bearing. The bearing contact surfaces of the central passage of the bearing which engage the external surfaces of the lead screw are generally planar in form and thus form line contacts with the external surface of the lead screw. The disclosed tape drive system is enhanced in that the play and loose fitting parts in conventional bearing systems are eliminated, and the subject bearing will act to confine the axis of the lead screw to a fixed position relative to the carriage structure of a high density tape drive or other device utilizing a precision lead screw positioning system.
