  • a model for Magnetic Tape guide friction reduction by laser surface texturing
    Tribology Letters, 2007
    Co-Authors: Bart Raeymaekers, Izhak Etsion, Frank E. Talke
    Abstract:

    The friction coefficient between a Magnetic Tape and a guide in a Tape path can be minimized by creating micro dimples on the guide surface with laser surface texturing. The dimples enhance the formation of an air bearing and reduce the friction coefficient between the Tape and the guide due to the increased spacing. A model is presented to optimize the geometry of the surface texturing parameters to maximize the average air bearing pressure and minimize the Tape/guide friction coefficient.

  • enhancing tribological performance of the Magnetic Tape guide interface by laser surface texturing
    Tribology Letters, 2007
    Co-Authors: Bart Raeymaekers, Izhak Etsion, Frank E. Talke
    Abstract:

    The friction coefficient is an important parameter in designing Magnetic Tape transports. We have introduced a novel approach to reduce the friction coefficient between guides and Magnetic Tape by laser surface texturing the cylindrical guides. The surface features enhance the formation of an air bearing and hence reduce the friction coefficient.

  • Lateral motion and edge wear of Magnetic Tapes
    Tribology International, 2003
    Co-Authors: J.h Wang, Ryan J. Taylor, Frank E. Talke
    Abstract:

    Lateral motion and edge wear are measured on Magnetic Tape, and the relationship between Tape edge wear and Tape lateral motion is investigated. Instrumentation for measuring Tape edge force is described. Tape edge force is measured at the Tape guiding position using a force-calibrated cantilever spring and a linear optical probe. Typical measurements of Tape lateral motion are given as a function of Tape tension, Tape direction, and path position. A technique for measuring Tape edge wear is introduced and wear measurements are presented as a function of load and the number of passes.

  • Magnetic Tape for data storage an enduring technology
    Proceedings of the IEEE, 2008
    Co-Authors: R H Dee
    Abstract:

    Magnetic Tape as used for data storage is reviewed. Attributes such as bit and track densities, Tape cartridge capacities and data rates are discussed in terms of the growth seen over time together with future trends envisioned for Tape. Tape has seen almost six orders of magnitude density increase since its introduction as a computer data storage device in the early 1950's with 1 Terabyte native capacity Tape cartridges being introduced into the market. The recording methods and technologies used for Tape data storage devices are outlined and Tapes position in the storage landscape discussed. Most of the world's data is stored and archived on Magnetic Tape primarily because of its long shelf life and favorable cost factors.

  • pollution prevention in the Magnetic Tape industry waterborne coating formulations for video Tape manufacture
    Waste Management, 1995
    Co-Authors: Song Cheng, Hong Fan, Naveen Gogineni, Brent Jacobs, J W Harrell, Irvin A Jefcoat, Alan M Lane, David E Nikles
    Abstract:

    A waterborne Magnetic Tape coating formulation was designed and used to prepare experimental Magnetic Tape samples in a pilot coating trial. The formulations contained a blend of a water-dispersed polyester and an ethylene/vinyl chloride copolymer emulsion, cross-linked with melamine-formaldehyde to give tensile properties (tensile strength 8.69 MPa and Young's modulus 245 MPa) that were comparable to a standard solvent-based binder composition. The pilot Tape trial used existing processing equipment, including calendering and slitting. The Tape had good Magnetic properties and excellent adhesion between the pigmented Magnetic layer and the base film, easily exceeding the 8 mm helical scan Tape standard of 0.96 N peel force. An economic impact analysis for the case of using our waterborne video Tape coating process in a conventional Tape manufacturing plant showed a significant decrease in costs for adopting the waterborne process.

  • carbon ternary alloy carbon optical stack on mylar as an optical data storage medium to potentially replace Magnetic Tape
    ACS Applied Materials & Interfaces, 2013
    Co-Authors: Hao Wang, Barry M Lunt, Richard J Gates, Matthew C Asplund, V Shutthanandan, Robert C Davis, Matthew R Linford
    Abstract:

    A novel write-once-read-many (WORM) optical stack on Mylar Tape is proposed as a replacement for Magnetic Tape for archival data storage. This optical Tape contains a cosputtered bismuth–tellurium–selenium (BTS) alloy as the write layer sandwiched between thin, protective films of reactively sputtered carbon. The composition and thickness of the BTS layer were confirmed by Rutherford Backscattering (RBS) and atomic force microscopy (AFM), respectively. The C/BTS/C stack on Mylar was written to/marked by 532 nm laser pulses. Under the same conditions, control Mylar films without the optical stack were unaffected. Marks, which showed craters/movement of the write material, were characterized by optical microscopy and AFM. The threshold laser powers for making marks on C/BTS/C stacks with different thicknesses were explored. Higher quality marks were made with a 60× objective compared to a 40× objective in our marking apparatus. The laser writing process was simulated with COMSOL.
