BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of splitting recording of a large capacity recording medium. For example, in various types of digital devices such as a disc recorder equipped with a large capacity recording medium such as a hard disk (HDD), the hard disk is recorded for a long time. The present invention relates to a method of splitting and recording a large-capacity recording medium for more suitably copying and recording data to be used for backup optical disks and the like.

Digital apparatuses, such as a disk recorder, which are widely used and widely used in general, include a large recording medium such as a hard disk, and record a data stream such as a broadcast program on the hard disk for a long time.

On the other hand, in the disc recorder, when an optical disc such as a CD, a DVD, or a Blu-ray disc (BD) is inserted into the device in order to back up the data recorded on the hard disc as described above, the optical disc is provided. It will be checked whether is a recordable optical disc.

Then, the data recorded on the hard disk is read out, and a series of data backup operations for copying and recording the data on the optical disk are performed. For example, the recording capacity of the CD is about 650 MB, and the recording capacity of the DVD is: Since the recording capacity of the Blu-ray disc is about 4.7 GB and about 21 GB, the user inserts an optical disc having a recording capacity suitable for the amount of recording data to be backed up into the device, and then performs a backup operation.

However, in a general disc recorder, when a data stream such as a broadcast program is recorded on the hard disk for a long time as described above, since data recorded continuously from the start of recording to the stop of recording is managed as one title, for example, When one recording title is 40GB, the user has to carefully examine the copy recording state while inserting and inserting a plurality of optical discs into the disc recorder.

Accordingly, the present invention was created to solve the above problems, and for example, in various types of digital devices such as a disc recorder equipped with a large capacity recording medium such as a hard disk (HDD), the hard disk may be used for a long time. In the case of performing a recording operation, the recording capacity of the preset target recording medium is checked, and the recording data of the appropriate recording capacity is automatically divided into different titles, and the automatically divided titles are connected to each other. It is an object of the present invention to provide a split recording method of a large-capacity recording medium for generating and recording (Link) information so that a subsequent data backup operation can be performed more efficiently.

In order to achieve the above object, the method of splitting and recording a large capacity recording medium according to the present invention comprises the steps of: checking a recording capacity of a preset target recording medium for recording data in a large capacity recording medium; And dividing the recording unit automatically when the amount of data corresponding to the recorded capacity of the identified target recording medium for backup is recorded.

In addition, in the first step, when recording data on the hard disk, the type of the predetermined backup target optical disk is checked, and in the second step, if the identified backup target optical disk is CD, 650 MB, 4.7 GB, And automatically dividing the amount of data corresponding to 21 GB into one title in the case of a Blu-ray disc, and generating connection information for connecting and reproducing the automatically divided titles to each other and recording the information as management information. It is done.

Hereinafter, a preferred embodiment of the method of dividing and recording a large capacity recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

First, the divided recording method of a large-capacity recording medium according to the present invention can be applied to various types of digital devices. For example, as shown in FIG. 1, a disc recorder to which the present invention is applied, an optical disc 10 ), Optical pickup 11, VDR (Video Disc Record) system 12, codec (13), microcomputer 14, OSD generator 15, memory 16, HDR system 17 , Hard disk 18, tuner 19, and the like.

On the other hand, in the microcomputer 14, for example, during operation control of the tuner 19 to tune to and receive a broadcast program, a hard key requesting recording of the broadcast program on a hard disk by a user's key input is performed. When a disk recording operation is received (S10), the HDR system 17 is controlled to perform a series of hard disk recording operations for recording the broadcast program on the hard disk 18.

In addition, the microcomputer 14 operates the OSD generating unit 15 to display a recording setting menu screen (S11). For example, as shown in FIG. 3, the recording setting menu is displayed. On the screen, a message (Select Backup Target Media) for selecting a target recording medium for backup is displayed along with a message (HDD Record Mode) indicating that the HDD recording mode is present.

Then, as the backup target recording medium, menu items for selecting one of the CD, the DVD, and the BD Blu-ray Disc are displayed, and Enter or Exit are displayed. Since a menu item such as the above is displayed, for example, the user can easily select and designate a DVD as the backup target recording medium.

On the other hand, in the microcomputer 14, if any one backup target recording medium is selected and designated through the above-described process, for example, if the DVD (DVD) is selected and specified, the HDR system 17 is operated and controlled, While continuously recording a broadcast program on the hard disk 18, the amount of data recorded so far is monitored (S13).

In addition, if the amount of data recorded to date corresponds to the recording capacity of the target recording medium (S14), for example, if the amount of data corresponding to 4.7 GB recording capacity of the DVD, the data recorded up to that point Is automatically divided into one title, and the recorded data is separately recorded as a new title. The microcomputer 14 generates link information for linking and reproducing the automatically divided titles as described above. Then, it records in the title information (S15).

When the recording is terminated while performing the above automatic division recording operation (S16), the user performs any corresponding operation requested by the user (S17), so that the user replaces and inserts a plurality of DVDs into the disc recorder. In addition, the automatically divided multiple titles can be appropriately and easily copied and recorded on each DVD to be backed up.

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.

The split recording method of a large-capacity recording medium according to the present invention as described above is, for example, in various types of digital devices such as a disc recorder equipped with a large-capacity recording medium such as a hard disk (HDD), for a long time to the hard disk. When performing the recording operation, the recording capacity of the preset backup target recording medium is checked. If the confirmed backup target recording medium is CD, 650MB, CD is 4.7GB, and Blu-ray Disc. (BD), the amount of recorded data corresponding to 21 GB is automatically divided into one title, and link information for link reproduction of the automatically divided titles is generated and recorded as management information. Titles automatically divided into hard disks are better suited for optical discs such as CDs, DVDs, and Blu-ray Discs used as backup media. It is a very useful invention that allows copying and recording.
