    摘要： A method and apparatus for manufacturing a magnetic recording medium using vacuum-deposition from an evaporated metal source having a very high efficiency and uniform deposition. The support onto which the magnetic film is to be evaporated is guided and conveyed along a curved path above a molten metal evaporating source at a substantially constant speed. The curved path is shaped such that evaporated metal flow lines connecting a central point on the evaporation surface of the molten metal in the evaporating source to corresponding intersection points on the support form the same angle of incidence with respect to the longitudinal direction of the support for all positions along the support where the film is to be deposited. Endless belt structures including guide rollers and magnets are used to form rising and falling paths for conveying the support along the desired curved path.

    摘要： THIS DISCLOSURE PROVIDES A MAGNETIC FILM WITH INDUCED UNIAXIAL ANISOTROPY, I.E., A FILM WITH AN EASY AXIS AND A HARD AXIS FOR MAGNETIZATION. THE PRACTIC OF THE DISCLOSURE INCLUDES DEPOSITION OF PARTIALLY IONIZED COMPONENTS OF A MAGNETIC MATERIAL ONTO A HEATED SUBSTRATE IN THE PRESENCE OF AN APPLIED ELECTRIC FIELD ADJACENT TO AND CONTIGUOUS WITH THE SURFACE OF THE SUBSTRATE. THE EASY AXIS OF THE INDUCED UNIAXIALY ANISTROPY IN THE DEPOSITED MAGNETIC FILM IS IN THE DIRECTION OF THE APPLIED ELECTRIC FIELD IN THE FILM. THE MAGNITUCES OF THE TEMPERATURE OF THE SURFACE OF THE SUBSTRATE AND OF THE ELECTRIC FIELD CONTROL BOTH THE MAGNITUDE AND DIRECTION OF THE UNIAXIAL ANISOTROPY IN THE FILM. THE DEGREE OF IONIZATION OF THE COMPONENTS OF THE FILM DURING VAPOR TRANSPORT TO THE SURFACE OF THE SUBSTRATE ESTABLISHES ANOTHER CONTROL OF THE RESULTANT INDUCED UNIAXIAL ANISTROPY IN THE FILM. EXEMPLARY MAGNETIC FILMS FOR THE PRACTICE OF THIS DISCLOSURE ARE NI-FE OF 81/19 RATIO OF THE ATOMIC COMPONENTS NI AND FE AND FILMS OF RARE EARTH COMPOUNDS AND ALLOYS, E.G., EUO COMPOUND AND EU-GD ALLOYS.

    摘要： Cathode structures are disclosed for use with pulsed cathodic arc deposition systems for forming diamond-like carbon (DLC) films on devices, such as on the sliders of hard disk drives. In illustrative examples, a base layer composed of an electrically- and thermally-conducting material is provided between the ceramic substrate of the cathode and a graphitic paint outer coating, where the base layer is a silver-filled coating that adheres to the ceramic rod and the graphitic paint. The base layer is provided, in some examples, to achieve and maintain a relatively low resistance (and hence a relatively high conductivity) within the cathode structure during pulsed arc deposition to avoid issues that can result from a loss of conductivity within the graphitic paint over time as deposition proceeds. Examples of suitable base material compounds are described herein where, e.g., the base layer can withstand temperatures of 1700° F. (927° C.).

    摘要： A treatment apparatus includes two can rolls provided on a transfer path through which a long resin film is transferred in a roll-to-roll manner in a vacuum chamber; and surface treatment means facing an outer circumference of each of the can rolls to treat a surface of the long resin film cooled by being wound around the outer circumference. The downstream can roll is provided with upper and lower two sets of feeding and sending systems, and one surface of the long resin film in contact with the outer circumference of the downstream can roll at a time when the long resin film travels through the lower one of the two sets of feeding and sending systems is opposite to the other surface of the resin film in contact with the outer circumference of the downstream can roll at a time when the resin film travels through the upper one.

Furthermore, the present technology also provides a magnetic recording tape having a layer structure including a magnetic layer, a base layer, and a back layer in this order, in which a reinforcing layer containing a metal or a metal oxide is disposed on either a surface of the base layer on the magnetic layer side or a surface of the base layer on the back layer side, and the number of black regions in an image obtained by binarizing an optical microscope image of a rectangular region of 64 μm×48 μm of the reinforcing layer is 70 or less.
