摘要： Disclosed is a method for aligning a rotating device such as an actuator assembly to a base of, for example, a disk drive. The device is rotatably mounted to the base about the pivot pin. The method may involve adjusting the angular position of the pivot pin relative to the base unless or until the actuator assembly rotates in a first plane parallel to a second plane containing a surface of the data storage disk. In one embodiment, the data storage disk is mounted for rotation on a disk rotation motor. The disk rotation motor, in turn, is mounted to a base. With the device positioned between the base and the data storage disk, the device is rotated about the pivot pin. While the device is rotated about the pivot pin, electrical current is provided to the device. The magnitude of the electrical current is proportional or inversely proportional to a distance D separating the device from the data storage disk. The electrical current is monitored as the device rotates about the pivot pin. When the monitored current is constant in magnitude as the device rotates about the pivot pin, the angle between the device and the base is such that the device should rotate in the first plane.

摘要： An actuator for coarse and fine positioning of a read/write head incorporates at least one pivoted member to position the read/write head relative to storage tape that stores the data. The pivoted member may be a beam supporting a read/write head or link of a four bar linkage and is typically pivoted on a carriage. The pivoted motion and the associated motion of the read/write head must not introduce excessive zenith tilt or the recording/writing of data will be unreliable.

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.

摘要： A tape drive is fabricated with a chassis and a bridge. The bridge acts to support the read/write head actuator and to also define the datum surfaces for locating a mating magnetic tape cartridge. The bridge is manufactured of materials which are highly rigid and stable dimensionally. The chassis of the tape drive is fabricated from materials such as plastics which are relatively flexible and do not have the rigidity of that characterized by the bridge. The more flexible chassis of the tape drive permits the isolation of distortions and distortionary forces in the chassis and does not transmit those forces and distortions to the bridge. The effect of the two piece arrangement is that the pieces may be made relatively inexpensively and retain reliability of much more expensive materials in manufacturing processes herefore considered necessary. The electronic circuits associated with and part of the tape drive may be protected by fabricating the bridge of an electrically conductive material and grounding it to insure that the chances for electromagnetic and electrostatic discharge are minimized.

摘要： Disclosed is a disk drive for storing data which includes disks and an actuator mounted on a frame or first housing part. A second housing part, when joined with the first housing part, forms a disk enclosure. The disk enclosure includes rails which have openings therein for mounting the disk drive to the user frame of a computer system. Deformable inserts are placed into the openings in the rails and screws are passed through openings in the frame of the computer system and into the inserts in the openings in the rails of the disk drive. The inserts are more forgiving and result in less distortion than in a mounting system in which the screws are passed directly into tapped holes in the rails of the disk drive. The inserts also electrically insulate the disk drive from the user frame of the computer system.

摘要： A pivot bearing structure formed of a leaf spring is incorporated into a rocker or force transmission member which whenever mounted to a carriage of a high density data tape drive system precisely defines the pivot axis of the rocker and provides a very high degree of stiffness in a vertical plane, that plane being parallel to the recording surface of the magnetic tape. The rocker derives motion from a voice coil motor (VCM) and transmits that controlled motion to a magnetic head which is suspended for movement in a vertical plane while in contact with a length of magnetic tape upon which data is recorded or from which data is read. The movement of the magnetic head may be very precisely controlled by energizing the VCM, because the pivot axis is extremely well defined due to the stiffness in the vertical plane of the pivot bearing. Movement of the VCM coil directly translates into movement of the magnetic head. The rocker is fabricated to form a cavity or pocket exposing a portion of the leaf spring to permit the bonding of another part to the leaf spring.
