    摘要： An apparatus according to one embodiment includes a module having a substrate, read and write transducers positioned towards a media facing side of the module, and a closure. The write transducers include write poles having media facing sides with negative, zero or near-zero recession from a plane extending along the media facing side of a substrate of the module. The read transducers each have two shields. Media facing sides of the two shields are recessed a same amount from the plane, and are more recessed from the plane than the write poles.

    摘要： A monolithic tape head module for high density recording. The module includes an actuator rail, and a tape head transducer array coupled to the actuator rail that includes a plurality of tape head transducer elements. A flex circuit is electrically coupled to the tape head transducer array, and includes first electrical conductors in a first flex circuit path that are coupled to a portion of the tape head transducer elements, and second electrical conductors in a second flex circuit path that are coupled to the remainder of the tape head transducer elements. An actuator shaft is connected to the actuator rail and coupled to a motor that is operated to move the actuator shaft. A plurality of flexures are mechanically coupled to the actuator rail and operated to restrict movement of the actuator rail to a direction aligned with the longitudinal axis of the actuator rail.

    摘要： In one general embodiment, an apparatus includes a magnetic head. The magnetic head has a first portion and a second portion, the first portion and the second portion together providing a tape bearing surface. The first portion has two pieces flanking the second portion in an intended direction of tape travel thereacross. The second portion has at least one array of transducers. A longitudinal axis of each of the at least one array is defined between opposite ends thereof. The longitudinal axis of each of the at least one array of transducers is oriented at an angle relative to the line oriented orthogonally to the intended direction of tape travel thereacross, the angle being between 0.2° and about 10°.

    摘要： Recording a servo write head spacing for writing servo tracks on a magnetic tape in a manufacturing environment. One or more environmental condition measurements of the manufacturing environment are received by a computer. A pair of servo tracks is written on a magnetic tape by a pair of servo write heads at a nominal spacing. The one or more environmental condition measurements of the manufacturing environment and information pertaining to the spacing of the servo tracks on the magnetic tape are recorded in one or more data stores.
