The combined total thickness of the oxide layer and the protective layer is 40 to 250 .ANG.. The oxide layer surface may be bombarded prior to formation of the protective layer for improving the bonding of the protective layer. A lubricant may be coated on the surface of the protective layer. The lubricant may be one of perfluoro alkyl ester of carboxylic acid, ester compounds of perfluoro polyether having carboxylic groups, and amine salt compounds. The reverse surface of a non-magnetic base film as a substrate has a centerline mean roughness R.sub.a and the maximum height R.sub.max of projections in the ranges of 0.015 .mu.m.ltoreq.R.sub.a 0.0070 .mu.m and 0.015.ltoreq.R.sub.max .ltoreq.0.070 .mu.m, respectively.

    摘要： A magnetic recording transfer method for use with the combination of a mother magnetic recording medium and a copy magnetic recording medium of a metal-deposited thin film type each. The two media are overlaid so that the column inclination of one medium will be opposite in direction to that of the other medium. This method comprises the step of externally applying a biased magnetic field to the combination of the media in such a manner that magnetized recordings on the mother medium will be transferred to the copy medium. The easy axis of the mother medium is positioned at an angle of 20.degree..+-.15.degree. with respect to the in-plane direction of the medium. The biased magnetic field is applied to the mother medium at an angle of 110.degree..+-.15.degree. with respect to the in-plane direction of the medium. This makes it possible to enhance the efficiency in transferring magnetic recording of the mother medium, especially the recordings of short wave lengths, and to minimize demagnetization of the mother medium. Furthermore, the ratio of the coercive force H.sub.CM of the mother medium to the coercive force H.sub.CC of the copy medium (H.sub. CM /H.sub.CC) is set to at most 1.5. This improves the magnetic recording transfer output of the copy medium and boosts the efficiency in the magnetic transfer of short wave magnetic recordings.

    摘要： A magnetic recording medium comprised of a nonmagnetic support; a magnetic metal thin film formed on one major surface of the nonmagnetic support; and a protective film of a corrosion-resistant metal or a multilayer protective film structure consisting of a corrosion-resistant metal film and a durable protective film of a hard material. A multilayer protective film structure is formed by sputtering a corrosion-resistant protective film and a durable protective film over the magnetic metal thin film while the nonmagnetic support travels along the circumference of a cooling cylinder by using at least one target of a corrosion-resistant metal and at least one target of a hard material, or by using a composite target composed of at least one corrosion-resistant metal and one hard material. The protective film suppresses the corrosion of the magnetic metal thin film and improves the corrosion resistance and durability of the magnetic recording medium.

    摘要： A magnetic recording and reproducing method for enhancing picture quality and other characteristics while suppressing the difference in reproduction output between two heads. The method involves using a double azimuth head arrangement for signal recording and reproduction by helical scan. The two heads A and B are provided so that their azimuth angles .theta..sub.A and .theta..sub.B do not coincide with each other. The actual recording direction represented by the sum of the azimuth angles .theta..sub.A and .theta..sub.B on the one hand and a still angle .alpha. between the heads A and B on the other is made as close to the direction of magnetic particle orientation on the magnetic recording medium as possible.
