摘要

PROBLEM TO BE SOLVED: To enable data copying control to be performed between a recording and reproducing device for data containing copy management information and a recording and reproducing device for data without containing the copy management information by providing an information processor having a function for discriminating the kind of data and also controlling the copy. SOLUTION: The data containing the copy management information is recorded and reproduced by a 2nd data recording and reproducing unit 2 and the data without containing the copy management information is recorded by a 2nd recording and reproducing unit 11. An external input controller 3 is given a control signal via an input/output interface 19 from the outside, and is operated to control the 2nd data recording and reproducing unit 2 and the 1st data recording and reproducing unit 11 in accordance with control contents of this control signal. At this time, the kind of data to be controlled is discriminated by the information processor 1, where approval or disapproval of the copy is controlled by a title of the data requested to be controlled through the external input controller 3.
