On the other hand, in the microcomputer 13, when a disc 10, such as a rewritable DVD, is inserted and seated in the apparatus, navigation information recorded in a specific area such as a lead-in area of the disc is searched and read, and the memory 15 ) Will perform a series of download operations.

When the user requests a data recording operation, the microcomputer 13 operates the VDR system 12 to encode data input from the outside into MPEG format data, and then the data area of the disk. When the current time counted by the timer 16 reaches the scheduled recording time set by the user, the VDR system 12 is controlled to operate in the normal recording operation for recording the data in the recording mode. After encoding the data into MPEG format data, a reserved recording operation for recording the data in the data area of the disc is performed.

However, if there is not enough space to record data on the disc during the normal recording or scheduled recording operation as described above, the microcomputer 13 automatically stops the recording operation or starts the disc. While deleting the data from the recording, new data is recorded, for example, if the recording operation is automatically stopped, there is a problem that the new data cannot be recorded, and also the data is deleted from the beginning of the disc. In this case, a problem arises in that important data is randomly deleted.

Therefore, the present invention was created to solve the above problems, and for example, in a disc recorder such as a DVD-Recorder, the data is recorded on a rewritable DVD (DVD-RW, DVD + RW) or the like. In the meantime, when the recording space is insufficient, the recording processing information recorded and managed as navigation information is searched and referred to, and according to the information on the method of securing the space for recording the data set by the user, the type of processing sequence, and the direction of the processing sequence. Another object of the present invention is to provide a recording control method in a disc recorder for efficiently recording new data while deleting previously recorded data.
