摘要： The present invention relates to the field of tape drives, tape transport, tape heads and tape head suspension. More particularly, the present invention is related to magnetic tape data storage and tape recorders that include components designed to minimize or eliminate head-to-tape contact to reduce or eliminate wear and contamination of tape drive heads. Methods and apparatus of the present invention may dynamically control the head-to-media spacing by moving locations of magnetic heads relative to a tape. Such apparatus may include components designed to minimize magnetic spacing. This may be accomplished using actuators that move the magnetic heads, that move the tape, or that move both the magnetic heads and the tape. This may include supporting a back surface of the tape. Alternatively, or additionally, the movement of the tape past the magnetic heads may be performed using mechanisms that contact and drive the back surface of the tape.

摘要： In one embodiment, a computer program product for determining a wrap angle includes a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se. The program instructions are executable by a processor to cause the processor to perform a method that includes receiving, by the processor, a measurement of a distance from an edge to a transducer, receiving, by the processor, a predefined height of tenting of a magnetic recording tape above the transducer, and determining, by the processor, a wrap angle for inducing tenting of the magnetic recording tape above the transducer at the predefined height when the magnetic recording tape passes over the edge in a direction of tape travel thereacross.

摘要： In one general embodiment, a method includes determining a distance from a transducer of a module to an edge of the module closest thereto, and selecting a wrap angle based on the determined distance for inducing tenting of a moving magnetic recording tape in a region above the transducer. In another general embodiment, a method includes running a magnetic recording tape over a tape bearing surface having at least one edge, and detecting signals from the tape at differing wrap angles for estimating a height of tenting of the tape above a transducer at each of the wrap angles. A wrap angle is selected to provide about a predefined height of tenting of the tape above the transducer.

摘要： A magnetic data storage system according to one embodiment includes a magnetic head; and guides on opposite sides of the magnetic head for directing a magnetic medium over the magnetic head. The magnetic head includes: outer portions each having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers; and a central portion positioned between the outer portions, the central portion having a tape bearing surface and an array of transducers selected from a group consisting of readers and writers. An inner edge of each of the tape bearing surfaces of the outer portions is adapted for skiving air from the magnetic medium when the magnetic medium travels in a direction from the central portion towards the respective outer portion. The guides are oriented to direct the magnetic medium to fly over a leading one of the outer portions, engage a leading edge of the tape bearing surface of the central portion, and engage an inner edge of the tape bearing surface of a trailing one of the outer portions.

摘要： An objective lens driving device includes an objective lens holder that holds an objective lens, plural elastic supporting members through that support the objective lens holder, tracking coils and that drive the objective lens holder in the tracking direction, tilting coils that tilt the objective lens holder with respect to the optical axis passing through the objective lens, a tracking control circuit that drives the tracking coils, and a tilting control circuit that drives the tilting coils. The tilting control circuit drives the tilting coils using a signal yielded by multiplying a tracking driving signal from the tracking control circuit by a specific scaling factor so as to cancel out a tilting force of the objective lens holder generated by the tracking coils.
