2. Description of the Related Art As a conventional technology of an information recording system,
For example, there is a system using a recording / reproducing apparatus for a mini disk and a reproducing apparatus for a compact disk. In the following, the mini-disc is referred to as MD and the compact disc is referred to as CD.

Now, as shown in FIG. 5, a CD reproducing apparatus 200 is connected to a MD recording / reproducing apparatus 100 by a digital cable 1.
Assume that the connection is made at 50 and music is recorded from a CD to an MD.

In this case, first, the MD recording / reproducing apparatus 10
0 while pressing the pause button 105
Press 3 to put the MD recording / playback device in a recording standby state. Then, if recording is to be started from the first song of the CD, the playback button 20 of the CD playback device 200
Press 7 to put the CD in playback state.

If recording is to be started from a song in the middle of a CD, a search is first made for the song to be recorded.
So, hold down the pause button 205 and play button 2
Press 07 to enter the playback pause state. Then, after releasing the recording pause state of the MD recording / reproducing apparatus 100, the recording from the CD to the MD is started by reproducing the CD.

[0006]

The above-mentioned MD recording / reproducing apparatus 100 has the following problems. If recording on the MD can no longer be performed while recording from the CD to the MD, the recording on the MD is automatically stopped. At this time, if the recorder is not at the recording location, for example, if the recorder is watching TV or going out of the room to a different room, it is necessary to know at which position in which song the recording was interrupted. To do this, the following complicated steps must be taken.

First, an MD track search is performed by the MD recording device 100. This track search is performed by sequentially sending tracks from the top track of the MD. Then, after confirming the last recorded track, the track is reproduced. By listening to the songs on the track, the recorder determines which portion of the song the recording was interrupted.

At this time, there is also a method of fast-forwarding and reproducing the music of the last recorded track to confirm at which part the recording was interrupted. However, a part of several seconds to several tens of seconds from the end of the track must be normally reproduced. Also, it is not easy to quickly search for a portion of about several seconds to several tens of seconds from the end of the track.

[0009] In consideration of such a procedure, it takes time for the recorder to obtain information as to where to start the next recording on the CD. Can not.

As a method of improving the above-described complicated procedure, there is a method of connecting the CD reproducing device 200 and the MD recording / reproducing device 100 with a control signal line in addition to the digital cable 150. In this case, the MD recording / reproducing device 1
When 00 stops recording, a control signal is transmitted to the CD reproducing apparatus 200. At the time of receiving this control signal, the CD reproducing device 200 is in a reproduction pause state. By playing back the CD player 200, the recorder can obtain information on where to start the next recording on the CD.

However, when such a control signal line is used, it is necessary to arrange the control signal line and the control signal. At this stage, there is no unified rule for such control signal lines and control signals. Therefore, a method of re-recording when recording is interrupted using a control signal line is proposed by creating a unique agreement for each manufacturer.

As described above, since each manufacturer adopts its own agreement, the MD recording / reproducing apparatus 100 and the CD
If the manufacturer is different from that of the playback device 200, re-recording using the control signal line cannot be performed, and the recorder must follow the complicated procedure as described above.

Accordingly, the present invention provides information for facilitating re-recording when the recording is interrupted because the recording from the first recording medium to the second recording medium can no longer be performed. An object of the present invention is to provide an information recording system, an information recording device, and an information recording method that can be provided.

[0014]

In the information recording system according to the first aspect, the information recording apparatus according to the second aspect, and the information recording method according to the third aspect, the content information is stored in the second recording medium. At the time of recording, if all of the acquired content information cannot be recorded on the second recording medium,
The attached information acquired at that time or information based on the attached information is output.

Thus, the user can obtain the additional information obtained from the first recording medium or the information based on the additional information when the recording cannot be performed any more on the second recording medium. Therefore, the content information of the first recording medium can be efficiently recorded on the second recording medium.

Thus, the user can easily obtain the result of comparing the amount of content information desired to be recorded from the first recording medium to the second recording medium with the recordable capacity of the second recording medium. . Therefore, the content information of the first recording medium can be efficiently recorded on the second recording medium.
