    摘要： In general, the invention provides two-sided magnetic data storage tape comprising azimuthal magnetic transition layouts that can substantially reduce demagnetization of recorded magnetic transitions on the surfaces of the tape. The invention specifically balances the goal of simplified media manufacture with the goal of reducing or avoiding media degradation when the tape is spooled. The two-sided magnetic data storage tape defines a substantially similar easy axis of magnetic anisotropy on a first and a second side of the tape, which can simplify media manufacture. Recorded magnetic transitions on the opposing sides of the tape define azimuths that are substantially different, which can help avoid media degradation when the tape is spooled.

    摘要： In one embodiment, the invention is directed toward a magneto-optic read head formed to suppress magnetic exchange coupling at regular intervals along a lateral direction of the read head. For example, in the region of the magneto-optic read head where light is reflected, i.e., the optical scanning region, the read head may be formed with a series of ferromagnetic exchange breaks that reduce lateral permeability of magnetic fields, and hence reduce lateral flux through the read head. In this manner, the effective resolution of the read head can be increased, thereby facilitating readout of data stored on narrower data tracks.

    摘要： The invention provides a system comprising a non-linear array of magnetoresistive (MR) heads arranged in a two-dimensional matrix for reading information stored on magnetic media. The non-linear array of MR heads may comprise a planar array formed by a plurality of linear arrays of MR heads stacked to define a plurality of layers. Each of the linear arrays may share at least one shield element with another linear array of the non-linear array. In general, each layer is offset by one written track pitch and the number of layers of the invention is equal to the number of written track pitches in a channel pitch. The invention can also be used in a system for reading and writing information to magnetic media at improved track pitches relative to conventional read/write systems.

    摘要： A thin film servo head apparatus is described that provides verification of time-based servo marks on a magnetic tape. The thin film servo head apparatus includes a plurality of thin film servo heads formed in a substrate. The substrate is canted such that servo gaps included in each of the thin film servo heads are substantially parallel to the time-based servo marks. Thin film servo heads eliminate the high labor, low yield machining process associated with conventional ferrite composite servo heads. Thin film servo heads may be fabricated in bulk on substrate wafers to reduce manufacturing time and cost. The invention described herein enables thin film servo heads to be used with time-based servo markings by defining a servo gap spacing such that when the substrate is canted, the servo gaps of the thin film servo heads substantially align with the time-based servo markings.

    摘要： A servo head comprising a write gap with a non-uniform width is described. It allows non-uniform width servo marks to be recorded on magnetic media. A servo head having a non-uniform width gap may create servo marks that facilitate servo position error signal calculations using time-based methods, amplitude-based methods, or both. This invention provides alternative methods for positioning servo heads and may increase reliability and precision by allowing redundant calculations.

    摘要： The invention is directed to patterns of amplitude-based servo windows that eliminate the need for conventional track identification marks, and various servo writing devices and head configurations that facilitate creation of such servo patterns. The patterns of servo windows may also eliminate the need for conventional synchronization marks. In accordance with the invention, the patterns of servo windows, themselves, can distinguish one track from another track in one or more servo bands and inherently provide synchronization without the need for synchronization marks between servo frames. In other words, the same amplitude-based servo windows that define the centerlines of the tracks can be arranged to provide track identification information and possibly inherent synchronization information.

    摘要： The invention presents techniques for verifying patterns, such as time-based servo marks, recorded on magnetic media. Patterns of this kind can be recorded on a magnetic medium using a recording head that includes a surface having a flux gap with a defined shape. The patterns may be verified with a verify head, having a surface with a flux gap with the defined shape or part of the defined shape. The verify head may include two or more ferromagnetic cores, with a flux gap associated with each core. Each core can independently verify part of the recorded pattern.
