障をきたしている。<Prior Art> Conventionally, in a magnetic ticket sheet, a magnetic recording layer is formed by applying a coating material containing magnetic powder and a binder on one surface of a support made of paper or a plastic sheet. Since the magnetic recording layers have different thermal contraction rates, curling occurs when processed into a magnetic ticket sheet after coating and drying, which impairs the running property of the magnetic ticket sheet inside the recording device and the recording / reproducing device. Further, the support and the magnetic recording layer,
Since the expansion and contraction rate due to moisture absorption and dehumidification when the humidity of the atmosphere changes, curling occurs on the magnetic ticket sheet,
The running performance of the magnetic ticket sheet inside the recording device and the recording / reproducing device is hindered. Further, when the support is paper, there is an advantage that the price is lower than that when the support is a plastic sheet, but since the dimensions change due to moisture absorption and dehumidification when the humidity of the atmosphere changes, the recording device and The running performance of the magnetic ticket sheet inside the recording / reproducing apparatus is hindered.
