摘要： A digital recording apparatus that obtains a digital stream including a plurality of frames, while recording the digital stream on a digital recording medium. This apparatus obtains, during recording, an instruction for a procedure in which a recording area is changed to another recording area which is not necessarily continuos with the recording area. When the instruction is obtained, the apparatus executes the procedure only when the number of frames which are recorded in the recording area is a predetermined number or more.
