Patent ID: 7719933

Claim:
An apparatus for recording record information onto an information record medium by a predetermined record format, said apparatus comprising: an area location device that locates a pre-record area normally assigned to control information, wherein the control information is required to perform a reproduction of the record information to which a copy is prohibited; and a data writing device that writes predetermined data so as to disable overwriting in the pre-record area, wherein the predetermined data prevents the control information from being recorded to the pre-record area located by said area location device, wherein, when record information that requires the control information to be reproduced is recorded onto said information record medium, said information is not reproducible, and when record information that does not require the control information to be reproduced is recorded onto said information record medium, said record information is reproducible, and wherein a lead position of the pre-record area is set in an arrangement not overlapping with a synchronization code in each of synchronization frames recorded on the information record medium.
