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： 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.
摘要翻译：在跟踪伺服系统中的磁带的记录/再现方法中，增加每个数据磁道的记录密度，同时抑制由磁带在宽度方向上的尺寸变化引起的记录/再现错误的发生。数据磁道各自被设置为具有比磁带1的宽度方向更靠近伺服磁道（41T-1至41T-5等）的逐渐减小的轨道宽度。通过这样的设置，数据磁道的宽度最靠近伺服磁道（41T-1至41T-5）的A1-41T-1至A1-41T-5等）可以最小化，从而可以显着增加数据磁道的数量。此外，即使当磁带1的尺寸由于诸如温度或湿度等外部环境的变化而在宽度方向上变化时，为了导致数据磁道的大的位移（A8-41T-1至A8-41T- 5）远离伺服磁道（41T-1至41T-5），数据磁头（A8）可以容易地对准数据磁道（A8-41T-1到A8-41T-5）数据磁道（A8-41T-1〜A8〜41T-5）的宽度尺寸的增加部分，从而可以确保从数据磁道读取数据信号（A8〜41T-1〜A8〜41T- 5），以提高再现精度。

The tape reel is provided with a cylindrical hub around which the magnetic tape is wound and a pair of upper and lower flanges. The average value of the thickness of a reference flange that receives the tape edge of the magnetic tape during tape winding is set greater than the average value of the thickness of the opposite flange. The tape receiving surface of the reference flange is formed into an inclined surface, and three or more air escape recess portions are formed on the tape receiving surface. The depth of each air escape recess portion is set not smaller than 0.05 mm and not greater than 0.40 mm. The occupation area of all the air escape recess portions is set to 30% to 80% of the total area of the reference flange. Such tape reel is housed in a magnetic tape cartridge.

摘要： A magnetic tape driving apparatus, which does not cause damage to either a magnetic head or a magnetic tape when making transition of the magnetic tape from a stopped state to a running state, when making transition of the magnetic tape from a running state to a stopped state, or when reversing the transportation direction of the magnetic tape, is provided. In a state where any one of a magnetic head and a magnetic tape moves and the other rests (i.e., a state where static friction may occur), such as at the time of starting transportation of the magnetic tape, at the time of stopping the tape in a running state, and at the time of reversing the transportation direction of the magnetic tape, a head displacing portion vibrates the magnetic head under the control by a displacement control portion, and thus no static friction occurs between the magnetic head and the magnetic tape. Therefore, the risk of causing damage to the magnetic head (such as an MR head unit equipped with an MR element) or the magnetic tape can be reduced.
