Abstract: A method is presented for setting a wrap angle of a read/write head having a servo element and multiple read elements, where the servo element and the read elements can detect a servo signal. The method includes moving a sequential information storage medium having a longitudinal axis and a servo band encoded therein adjacent to the read/write head. The longitudinal axis and a flat upper surface of the read write head define the wrap angle. The method further includes detecting the servo signal using one of the read elements. If the read element is unable to detect the servo signal, then the remaining read elements are sensed to detect the servo signal.

Abstract: The invention is directed to techniques for erasing data storage tape for reuse. In an embodiment, an erase head module for erasing data storage tape comprises a set of erase gaps and one or more servo read elements. The set of erase gaps is configured to coincide with data bands of the data storage tape to allow erasure of only the data bands of the data storage tape while not erasing servo bands of the data storage tape. The one or more servo read elements detect one of the servo bands of the data storage tape when the set of erase gaps are proximate the data bands of the data storage tape to allow the erase head module to accurately track the data bands with the set of erase gaps.

Abstract: The present invention relates to a magnetic head which can be kept in stable contact with a magnetic tape and has improved production efficiency, a manufacturing method therefor, and a magnetic tape device. The magnetic head according to the present invention includes a substrate and two auxiliary members, having a tape bearing surface to be in sliding contact with a magnetic tape. Reproducing and recording elements in alignment with each other along a tape running direction are arranged in the substrate along a tape width direction. The two auxiliary members are joined to two ends, respectively, of the substrate, constituting the tape bearing surface together with the substrate. The substrate or the two auxiliary members are formed with slopes extending from join-faces between the substrate and the two auxiliary members to the tape bearing surface to make clearances for the magnetic tape. Since the running magnetic tape can be drawn to the clearances by negative pressure generated at the clearances, it can be held in parallel with the tape bearing surface.

Abstract: 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.

Abstract: A plurality of read/write heads is disclosed for a magnetic media storage system, such as, for example a magnetic tape drive. Each head can include a plurality of data channels. In addition to enhancing data throughput, the plurality of read/write heads can be aligned to read or write bands of tracks on a magnetic tape with only one positioning mode (e.g., without coarse position actuation and control), and also obtain optimum yield and crosstalk values.
