Magnetic recording medium having a dimensional variation
摘要
說明書
As a result of the observation, in a case where the end face of the tape was not flat, with a step or a tape protrusion, the tape was assumed to have a winding deviation. Furthermore, as more steps or tape protrusions were observed, “winding deviation” was assumed to be worse. The above-mentioned determination was made for each sample. The winding deviation of each sample was compared with the winding deviation of Comparative Example 1 as a reference medium to determine whether the winding deviation was favorable or not in the following way.
Favorable: a case where the winding deviation of the sample is equal to or smaller than the winding deviation of the reference sample (Comparative Example 1)
Defective: a case where the winding deviation of the sample is larger than the winding deviation of the reference sample (Comparative Example 1)
Tables 1 and 2 show the configurations and evaluation results of the magnetic tapes according to Examples 1 to 21 and Comparative Example 1.
