The device includes a first memory circuit which sequentially stores digital signals reproduced by the reproduction head, a circuit which identifies the attribute of a reproduced digital signal and a write control circuit which judges, based on the result of the identification provided by the identification circuit, whether digital signals of a prescribed unit length included among digital signals stored in the first memory have the same attribute, and produces a write signal in response to the judgment. Also provided is a second memory which is connected to the first memory and stores the digital signals which have the prescribed length and are judged to have the same attribute in response to the write signal.
