ABSTRACT:
An information processing device processes specific information recorded on a recording medium, and has a characteristic identification unit and a processing unit. The characteristic identification unit identifies the reflection characteristic of the recording medium. The processing unit processes the specific information recorded on the recording medium according to the identified reflection characteristic. The reflection characteristic is either a first characteristic such that the reflectance of light reflected by a recorded region of the recording medium (referred to as first reflectance) is greater than the reflectance of light reflected by an unrecorded region of the recording medium (referred to as second reflectance), or a second characteristic such that the first reflectance is less than the second reflectance.
