ている。2. Description of the Related Art A conventional method for manufacturing a magnetic recording medium of this type is described in, for example, “Research on high-performance coated video tapes” by Hajime Kawamata, P13.
2-8, video tape manufacturing process), and the configuration shown in FIG. That is, a magnetic coating material is applied on a synthetic resin base, dried, and temporarily wound. After that, the roll is unwound to perform surface molding, and this is wound and cured in a roll shape. After curing, it is unrolled from the roll and shredded.
発明が解決しようとする問題点 しかし、このような構造では表面成形後、一度ベース

硬化後の冷却過程においてもロールに冷却ムラが生じ巻
芯と巻外で特性差がでるという問題があった。However, in such a structure, after the surface is molded, since the base is wound once, there is a temperature gradient between the core of the roll wound in the hardening step and the outside of the winding, so that the hardening takes a long time. There is a problem in that, and also in the coating film, there is a problem that the holding time of the set curing temperature varies between the core and the outside. Further, there is a problem in that even in the cooling process after curing, cooling unevenness occurs on the roll and a difference in characteristics occurs between the core and the outside.
そこで、本発明は磁気記録媒体の特性のバラツキを最
小限にするとともに磁気記録媒体の製造時間を短縮し、
コストダウンをはかるものである。Therefore, the present invention minimizes the variation in the characteristics of the magnetic recording medium and shortens the manufacturing time of the magnetic recording medium,
The cost is reduced.

なコストダウンに連がるものである。Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic view showing an embodiment of a method for manufacturing a magnetic recording medium of the present invention. Reference numeral 1 is an unwinding portion of the roll-shaped support. Reference numeral 2 is a coating portion for applying a magnetic coating material to the support unrolled from the unwinding portion 1, 3 is a drying zone for drying the magnetic recording medium 4 having the support coated with the magnetic material, and 5 is the surface of the magnetic recording medium 4. A guide roll leading to the treatment step 6, a curing zone 7 for curing the surface-treated magnetic recording medium 4,
Reference numeral 8 is a slitter for slitting the hardened magnetic recording medium 4 while cooling it by the cooling unit 9. Reference numeral 10 is a winding section for winding the magnetic recording medium 4 having the slits completed.
With the above-described structure, the magnetic recording medium 4 is coated with the magnetic material on the support, and then continuously dried, surface treated, cured and slit to be treated and processed. Therefore, the treatment / processing on the same support becomes uniform, and variations in characteristics are eliminated. Further, as compared with the case where the material is once wound, there is no loss of time between steps due to continuous production, resulting in a significant cost reduction.
