Abstract: A method for manufacturing a magnetic recording medium of the present invention includes a magnetic layer forming step in which a drying process is performed. The drying process includes: a pre-heating stage in which a magnetic coating film is heated until the surface temperature of the magnetic coating film stops rising and reaches a substantially constant temperature; a constant rate drying stage that is performed after the pre-heating stage in which the surface temperature of the magnetic coating film is held substantially constant; and a falling rate drying stage that is performed after the constant rate drying stage in which the surface temperature of the magnetic coating film is increased to be higher than the surface temperature during the constant rate drying stage to harden the magnetic coating film. The constant rate drying period in which the constant rate drying stage is performed is 0.2 seconds or more.

Abstract: A magnetic tape comprising a non-magnetic substrate and at least one magnetic layer formed on one surface of the non-magnetic substrate, characterized in that magnetic particles contained in an uppermost magnetic layer of the magnetic layer are substantially granular particles with a particle size of 30 nm or less, and that the ratio of a coercive force HcM in the machine direction to a coercive force HcT in the transverse direction, i.e., [HcM/HcT], is at least 2.2. This magnetic tape has a capacity capable of corresponding to mass storage of 1 TB or more, and achieves a high ratio of reproducing output to noises (C/N), particularly for signals within a short wavelength range, thus showing excellent high-density recording performance.

Abstract: There is provided a magnetic recording medium comprising a flexible non-magnetic substrate, and a magnetic layer containing magnetic particles, formed on at least one surface of the flexible non-magnetic substrate, and this magnetic recording medium is characterized in that an uppermost layer formed on the side of the magnetic layer is a non-magnetic layer with a thickness of 1 to 50 nm, which contains a resin and has a surface roughness (P-V) of 2 to 20 nm. This magnetic recording medium is excellent in high density recording performance, and is highly reliable in durability.

Abstract: A thermal recording medium including a base layer containing a resin having a functional group which chemically bonds with a metal having a low melting point, such as Sn-Pb alloy, and a thermal recording layer made of a thin film with low resistivity of a low melting point metal formed on said base layer such that when a part of the thermal recording layer is heated, the heated part melts and perforates to record information.

Abstract: An ink composition for thermal transfer printing, which composition comprises a coloring agent and a mixture of an aromatic ester-containing polyurethane and at least one thermoplastic material selected from the group consisting of thermoplastic resins and waxes, has a good transferring property and improved anti-blocking and forms printing having good durability.
