The medium has a recording layer (5) consisting of a film with rectangular magnetization which contains recording bits for recording information and a playback layer (1) in a signal playback region, in which the magnetization of each recording bit is copied, which is held in the state of rectangular magnetization. A first screen layer (4) is formed between the recording layer and the playback layer to prevent the magnetization of other recording bits in the recording layer than the bit to be played back from being copied into the playback layer.
