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： A magnetic head is arranged between two reels around which a magnetic tape is wound and contacts one side of the magnetic tape spanned between the two reels. A driver moves the magnetic head. A controller causes the driver to generate a driving force for pressing the magnetic head against the one side of the magnetic tape while keeping the magnetic head in contact with the magnetic tape. It is possible to cause the magnetic head to stably contact the magnetic tape even when the running position of the magnetic tape varies in accordance with the winding state of the magnetic tape around the reel.

摘要： A magnetic tape driving apparatus of the present invention includes a support member for separating a magnetic tape from a magnetic head on at least one of a tape input side and a tape output side of the magnetic head. The support member separates the magnetic tape from the magnetic head at least when a tape driving portion causes the magnetic tape to start running and/or to stop running. With this configuration, the magnetic tape driving apparatus does not suffer from damage to the magnetic head and the magnetic tape when the magnetic tape makes a transition from the stopped state to the running state and vice versa or changes in the running direction.

摘要： A method for avoiding tape stiction is provided with a tape drive with a pair of motors for driving a pair of tape reels for conveying data tape across one or more read/write heads. Tachometers measure rotation of the pair of tape reels. Motion of the tape is started and rotation of the tape reels is measured by the tachometers. The measurement of the rotation of the tape reels is compared to determine if there is enough slack associated with tape stiction. The location of tape stiction is stored and weighted. Another method stops motion of the tape at a location wherein excessive tape stiction has not been detected. A tape drive is provided for performing methods for avoiding tape stiction.

摘要： A tape recording head is provided comprising a support plate having a contoured surface with an opening in the contoured surface which allows head chips to protrude far enough to allow proper head tape contact for recording. The support plate is fixed on a coarse actuator so that the support plate and coarse actuator move together perpendicular to the motion of the recording tape. The head chips comprising rowbar substrates containing a multiplicity of recording elements are supported on a carrier mounted on a fine actuator and are not fixed to the support plate to allow low mass fine actuation.
