摘要： Magnetic storage tape and techniques for erasing and writing to magnetic storage tape having a perpendicular squareness greater than 50 percent and a longitudinal squareness less than 50 percent are described. In general, the magnetic tape may be biased with a remanence magnetization, or magnetic orientation, in any direction. One or two head systems may use various magnetic field patterns to create the desired remanence magnetization. Servo marks may have a remanence magnetization in an opposite magnetic orientation than that of the remaining bias on the servo track, e.g., substantially perpendicular to the magnetic tape. In some examples, a write head may alternate the direction of the magnetic field to continuously bias and write servo patterns to the magnetic tape. In addition, a symmetrical servo mark may be created in the magnetic tape with a write head having a gap width approximately equal to the length of the servo mark.

摘要： Magnetic storage media that include a multilayer structure are described. In general, the magnetic storage media include a substrate, an underlayer that includes a plurality of underlayer particles formed over the substrate, and a magnetic layer that includes a plurality of magnetic particles formed over the underlayer. The magnetic layer may define a saturated magnetization and thickness product less than or equal to approximately 1.00 memu per square centimeter, and the magnetic particles may be selected from the group consisting of magnetic platelet-shaped particles and magnetic particles with an aspect ratio less than or equal to approximately 1.5. In addition, the described magnetic storage media may exhibit minimal interlayer diffusion between the underlayer and magnetic layer. Reduced interlayer diffusion between different layers of a magnetic recording medium may result in an improved magnetic recording surface for recording and storing data.

摘要： A magnetic recording tape configured for increased surface lubricity includes an elongated substrate and a magnetic side disposed on the substrate. The magnetic side includes a magnetic recording layer defining an exposed magnetic recording surface opposite the substrate, and a support layer deposited on the substrate between the substrate and the magnetic recording layer. The support layer includes nano-particles configured to release lubrication to the exposed magnetic recording surface. In this regard, the support layer configures the exposed magnetic recording surface to have a surface lubrication to total lubrication ratio (SL ratio) of greater than about 5%.

摘要： In an embodiment, a data storage tape includes a first side including recorded data and a second side including recorded error correcting code data for the recorded data on the first side. In another embodiment, a data storage tape comprises a first side including recorded data and a second side including a copy of the recorded data. Embodiments of the invention may distribute related data across both sides of a data storage tape and as a result may reduce the probability that a location-dependent error in the data storage tape will result in irretrievable data loss. Embodiments of the invention may be particularly useful for systems that can simultaneously retrieve or record data on both sides of a dual-sided data storage tape.
