Embodiment 1
[0043] figure 2 It is a schematic functional block diagram of the recording / reproducing device 10 in this embodiment, and its structure and operation will be described together below. In addition, the following description assumes that the program is recorded in the disk medium (hereinafter referred to as "medium") 13 by the recording means 12 in the form of a file.
[0044] First, in order to play back the recorded program, the user uses the operating mechanism 11 such as a remote controller to give an instruction, and the playback mechanism 14 that receives the instruction reads out the file management information recorded at a specific location on the medium 13, and checks whether the target file is recorded in or not. Where on the media 13. And, in case the recorded position of the target file is known, the data is read out from this position, and the read data is transferred to the image output processing mechanism 16 ( image 3 , step S41).
[0045] Since the recordi...
Embodiment 2
[0062] According to the recording / reproducing apparatus 10 described in Embodiment 1 above, files can be easily deleted. When adopting such a structure, it is preferable to consider a countermeasure when a file to be held is accidentally deleted. Only the differences between this embodiment and the above-mentioned embodiment 1 will be described below.
[0063] First, usually, when a processing request for file deletion occurs, the file deletion is realized by deleting the file information of the requested object from the file management information. That is, the data of the file itself still remains on the medium 13, but because the area where this data is recorded is not used and processed in the file management data (equal to deletion in fact), it is overwritten during the next recording.
[0064] In contrast, in this embodiment, once there is a need to delete a file, the deletion mechanism 15 will add information about the scheduled deletion (hereinafter referred to as "sc...
Embodiment 3
[0081] Such as Figure 7 As shown, the recording / reproducing device 10 of this embodiment is equipped with a protection mechanism 18 capable of protecting programs recorded on the medium 13 . Like judging to delete a file, in most cases, when watching this program, judging that you want to save the file.
[0082] Therefore, when the end of file playback is detected, an inquiry about the protection of this file is made instead of an inquiry about file deletion.
[0083] For example, once it is detected that the read position reaches the end of file, that is, as Figure 5B As shown, information such as "Do you want to protect this file" is displayed in dialogue D. This is used to ask the user whether to protect the replayed file ( Figure 6 , Step S51→S52: No→S53: Yes→S54→S55).
[0084] As described in Embodiment 1 above, the mechanism for detecting that the reading position has reached the end of the file may be the playback mechanism 14 described above, or may be a mechani...
