Abstract
By the control information recording method, control information to control at least one of recording and reproducing operations of record information on an information record medium is recorded onto a guide track of the information record medium. The control information recording method is provided with the steps of: generating a control information timing signal one after another at an interval corresponding to a length of a control information unit equal to an N (N: predetermined integer not less than 2) multiple of a length of a record information unit of the record information; and recording the control information onto the guide track of the information record medium, on the basis of a timing corresponding to the control information timing signal.
