摘要

An information processing device ( 225 ) is a device for processing specific information recorded to a recording medium ( 100 ), and has a characteristic identification unit ( 204 ) and a processing unit ( 226 ). The characteristic identification unit ( 204 ) identifies the reflection characteristic of the recording medium ( 100 ). The processing unit ( 226 ) processes the specific information recorded to the recording medium ( 100 ) 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 ( 100 ) (referred to as first reflectance) is greater than the reflectance of light reflected by an unrecorded region of the recording medium ( 100 ) (referred to as second reflectance), or a second characteristic such that the first reflectance is less than the second reflectance.
