Description

  The present invention relates to a recording / reproducing apparatus and a recording medium search method, and more specifically, a title or disk to be viewed among various recording disks (DVD, BD, etc.) recorded by a recording / reproducing apparatus such as an HDD-integrated AV recorder. Is related to the method of searching.

  Conventionally, HDD-integrated AV recorders include recording / reproducing DVDs (Digital-Versatile-Disk), CDs, recordable discs, recording / reproducing devices that can read / write on reproduction-only discs, and recently, BDs. The number of recording / playback devices that incorporate (Blu-ray-Disk) and the like in one housing is increasing. In the HDD, there is no problem because the title and content recorded in the HD are managed in the file management area in the HD. However, the DVD, CD disc and BD disc are removable recording discs. It will be ejected from the housing and stored. In the case of a DVD or CD disk, the file management is managed for each disk. Similarly, file management of BD discs is also managed for each disc. For this reason, there is no problem in inserting one disk into each drive.

  However, the disc that the user wants to see or add to the disc must be relied on his / her own memory and label when ejected from the device. It is necessary to find out.

  Here, there are CDs, DVDs, BD-ROMs, etc. even with a read-only disk, and their storage capacities are about 650 MB, about 4.7 GB (about 8.5 GB for a two-layer disc), and about 25 GB (two layers), respectively. Is about 50 GB). One BD can store the capacity of about 77 CDs. In addition, various types of discs such as CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RW, DVD + R, and DVD + RW exist as recordable discs. In such an environment, when a user wants to search for a desired title, for example, a large number of removable recording disks are inserted into the HDD-integrated AV recorder one by one, and after launching the title screen, which one is necessary for the thumbnail It was necessary to search manually for a long title. Further, the capacity is increased from the CD system to the DVD system and further to the BD system. On the other hand, the larger the capacity is, the more time is wasted searching for necessary discs and titles. Therefore, a function is required for automatically managing these discs and managing titles so that a desired disc can be searched.

Here, for example, Patent Document 1 discloses an information search device that enables search using feature data for all music data recorded on a recording medium. The information retrieval apparatus includes a drive for reading / writing music data from / to a disk, a recording / playback memory for temporarily storing compressed music data, a playback decompression unit and playback unit for playback, a compression unit for recording, Control of writing or reading music data to / from the drive based on the remaining capacity of the feature extraction memory, feature extraction decompression means and feature extraction means, recording / playback memory and feature extraction memory And a feature parameter list update unit that reads and updates the feature parameter list of the music data, and the recorded feature-unextracted music data is recorded as the intermittent time of disk access that occurs during playback or recording. Recorded on a disc-shaped recording medium by extracting features at high speed. It is obtained by allowing a search by feature data with respect to music data all.
JP 2001-126391 A

  However, the invention described in Patent Document 1 enables search by feature data for all music data recorded on a disk-shaped recording medium. When there are a large number of disk-shaped recording media, It does not search which disc contains the desired music data. Therefore, when the disc is ejected from the apparatus, it is necessary to rely on the user's own memory, labels, etc., and when there are a large number of discs, it is necessary to spend a lot of wasted time searching for the disc that the user desires. is there.

  The present invention has been made in view of the above circumstances, and in a recording / reproducing apparatus including a removable recording medium such as an optical disk and a plurality of drive units for reading and writing to a hard disk (HD), File information (recording medium identification information, content title information, etc.) is stored in a predetermined area of the HD, and a desired content is displayed by displaying a list of stored file information in accordance with an instruction from the user.
