摘要： A multi-channel tape recording head or apparatus that has cable connection pads aligned along a direction that runs substantially perpendicular to a multi-channel tape recording head actuation direction, which allows a ribbon-type external cable, connected to the cable connection pads, to bend in its most flexible direction when the multi-channel tape recording head moves.

摘要： An integral recording head, for use in a linear tape drive system, includes a circumferentially grooved roller guide assembly and a recording head actuator assembly. The circumferential groove feature is incorporated on the surfaces of the roller guide assembly, and provides a substantial frictional contact force that acts to reduce the lateral motion, and further attenuates high frequency lateral disturbances of the magnetic tape. The reduced high frequency content of the lateral disturbances significantly improves the ability of the actuator to achieve a desired track following control. The grooved roller guide assembly is formed integrally of two solid cylindrical contact surfaces separated by a circumferential slot that accommodates the recording head actuator assembly.

摘要： A method and apparatus for writing timing-based magnetic servo band patterns on magnetic storage media. The apparatus includes a magnetic head and a tri-state driver. The driver is adapted to control three magnetic head states including two writes states having positive and negative current outputs, respectively, for performing a write sequence and a rest state, having no current output for avoiding overwriting of the magnetic pattern between write sequences. The driver is further adapted to gradually change the magnetic head state from a rest state to a write state before beginning a write sequence and to gradually change the magnetic head state back to a rest state upon completing a write sequence. Thus, strong uniform signal pulses are produced upon playback of the magnetic pattern.

摘要： A recording head to simultaneously read or write data to and from a plurality of tracks on magnetic tape, while compensating for shrinkage or expansion caused by moisture, temperature, creep caused by tension in the tape, creep caused by dimensional instability of the tape, as well as other causes. A recording head in accordance with the invention includes a leading module and a trailing module. In order to accommodate fluctuation in tape dimensions due to expansion or shrinkage, the leading and trailing modules may be offset with respect to one another. By offsetting one module with respect to the other, selected read and write elements from one module may more closely align with certain tracks of an expanded or shrunk tape, while other read and write elements from the other module may more closely align with other tracks on the tape.

摘要： Disclosed is a magnetic tape media having addressing data information superimposed on prerecorded track following servo information. The servo information is recorded in magnetic flux transition patterns defining at least one longitudinal servo track. A servo burst pattern of at least two repeated pairs of non-parallel magnetic flux transitions is provided, at least one of which transitions is slanted or otherwise continuously longitudinally variable across the width of the servo track. At least two transitions of the repeated pairs are shifted longitudinally with respect to other of the transitions, the shifted transitions comprising the superimposed addressing data information. Also disclosed is a magnetic tape media having prerecorded combined servo and data information recorded in repeated pairs of magnetic flux dual transitions, at least one of the repeated pairs of dual transitions having a different width with respect to other of the transitions, the different width transitions comprising data information.

摘要： A bidirectional linear thin film tape head and drive are disclosed with a flat contour on a wear resistant ceramic substrate. At least one thin film transducer is provided on a side of the substrate, forming one edge to the flat transducing surface, and another edge is formed at the opposite side of the flat transducing surface. In one embodiment, both the transducer edge, with an alumina overcoat protecting the transducer, and the opposite edge of the flat transducing surface form outer tape path edges, and in another embodiment, the thin film transducer is protected by a ceramic closure that covers the thin film transducer and forms an extension to the flat transducing surface which provides an outer tape path edge. The edges remove the air entrained by the tape moving relative to the head in either direction to allow contact or near contact recording with the flat transducing surface.
