摘要： 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. The first solvent is made of one solvent or two or more solvents having different boiling points, and the difference (Tb−Ts) between the boiling point Tb of the solvent having the lowest boiling point among the solvents contained in the first solvent and the surface temperature Ts of the magnetic coating film during the constant rate drying period is 1 to 50° C.

摘要： A magnetic tape driving apparatus of the present invention includes a support member for separating a magnetic tape from a magnetic head on at least one of a tape input side and a tape output side of the magnetic head. The support member separates the magnetic tape from the magnetic head at least when a tape driving portion causes the magnetic tape to start running and/or to stop running. With this configuration, the magnetic tape driving apparatus does not suffer from damage to the magnetic head and the magnetic tape when the magnetic tape makes a transition from the stopped state to the running state and vice versa or changes in the running direction.

摘要： In a recording/reproducing method of a magnetic tape in a tracking servo system, a recording density of each data track is increased while inhibiting occurrence of a recording/reproducing error caused by a size change of a magnetic tape in the width direction. Data tracks are each set to have a smaller track width stepwise as closer to servo tracks (41T-1 to 41T-5 etc.) in the width direction of a magnetic tape 1. With such a setting, the width of the data tracks (A1-41T-1 to A1-41T-5 etc. ) closest to the servo tracks (41T-1 to 41T-5) can be minimized, thereby enabling a significant increase in number of the data tracks. Further, even when the size of the magnetic tape 1 changes in the width direction due to a change in external environment such as a temperature or moisture, to lead to large displacement of the data tracks (A8-41T-1 to A8-41T-5) distant from the servo tracks (41T-1 to 41T-5), the data head (A8) can be readily aligned to face the data tracks (A8-41T-1 to A8-41T-5) in the reproduction by an increased portion of the width size of the data tracks (A8-41T-1 to A8-41T-5), and it is thereby possible to ensure reading of data signals from the data tracks (A8-41T-1 to A8-41T-5) so as to improve reproduction accuracy.
