An information medium evaluating method includes, in the following order: a recording process that records data onto a recordable information medium to be evaluated; a rubbing process that rubs a processing member against a data recording surface of the information medium; a reading process that reads the data from the information medium; and an evaluating process that evaluates the information medium based on a result of the reading process and evaluation standard data. During the rubbing process, the processing member is rubbed onto only part of a region in a circumferential direction of the information medium. |
