Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a dubbing apparatus for recording a signal reproduced by a disc player section in a tape recorder section.

(Summary of the Invention) According to the present invention, by inputting the recording time of a tape to be used, an operation is performed based on the above-mentioned recording time and the playing time of each music number included in index information of a disk to be reproduced by a disk player. Automatically select a combination of song numbers to be recorded on the tape so that the remaining time of the tape is shortened, and according to the selection, the disc can be reproduced by the disc player and recorded on the tape by the tape recorder. In this way, the remaining time of the tape can be reduced.

(Prior Art) Recently, as a dubbing device for recording a signal reproduced by a disk player unit in a tape recorder unit, a recording time of a tape to be used is input to record a recording time and a track number included in index information of the disk. There is a commercial product that performs a performance based on the performance time, determines the number of songs that can be completely recorded on a tape, for example, from the first song to the number of songs that can be completely recorded, and performs dubbing recording in accordance with this.

(Problems to be Solved by the Invention) However, in the above-described conventional device, for example, the first to fifth songs can be completely recorded, and when the sixth song is cut off halfway, the first to fifth songs are recorded. Therefore, the remaining time of the tape greatly varies depending on the playing time of the sixth tune, and the longer the playing time of the sixth tune, the longer the remaining time of the tape, which is extremely wasteful.

(Means for Solving the Problems) According to the present invention, in order to solve the above problems, a signal reproduced by a disc player is recorded by an auto-reverse tape recorder which performs recording and reproduction on a tape capable of recording and reproducing in both directions. Recording time input means for inputting the total recording time of the tape used in the tape recorder section, and the abbreviation of the total recording time input by the recording time input means with the input of the editing instruction signal. From the half time, subtract the time value obtained by sequentially adding the playing time of each music number of the index information of the disc obtained from the disc player section, and set the subtracted value to be in a positive range, In addition to the tape one-way recording procedure, a search is made for a song number that does not add the above and whose playing time is shorter than the subtraction value at that time. Recording means for storing a combination of song numbers selected by the editing means, wherein the disc player reproduces disc information in accordance with the contents stored in the storage means, and The information is recorded on the tape by the above-mentioned auto reverse tape recorder.

(Operation) Therefore, according to the present invention, the editing means subtracts the time value obtained by sequentially adding the playing time of each music number from approximately half of the total recording time inputted by the recording time input means. And
After setting the subtraction value to be in the positive range, search and add the song numbers that are not added and whose playing time is smaller than the subtraction value, and add the song number selected by the editing unit to the storage unit. Is stored, and then the disk information is reproduced and recorded on the tape in accordance with the stored contents of the storage means, so that the remaining time of the tape can be reduced and the tape can be effectively used.

For storing index information read from the disk by the optical pickup 1, a storage function for storing the tape recording time inputted by the tape length setting switch 15, and an editing function. Switch 14
By reading the playing time of each song number and the recording time included in the index information with the ON operation of the above and calculating based on both times, the remaining time on both sides A and B of the tape is shortened. An editing function for selecting a combination of song numbers to be recorded on the A and B sides of the tape, a storage function for storing the combination of the selected song numbers, and recording and playback switches 11, 1
The function of reading the combination of the above-mentioned music numbers under the condition of ON of 3 and sending an instruction signal to the servo circuit 2 and the signal processing circuit 3 in accordance with the contents, thereby reproducing the disk in the disk player section, from the start of the reproduction operation of the disk player section A function to shift the tape recorder unit to the recording operation state by sending a recording operation start signal to the tape recorder unit slightly earlier, a high-speed fast forward signal to the tape recorder unit when the last song recorded on each side of the tape is completed It has a sending function and the like.

The tape recorder unit 10 has an auto reverse function, a function of outputting a tape A / B surface classification signal, and the like.

Next, the operation procedure and operation of dubbing recording will be described. Here, the tape used is C-60 (recording time 60 minutes on both sides A and B), and the disk has 12 recorded songs and a total playing time of 63 songs.
The case of minutes and 30 seconds will be described as an example. FIG. 2 shows the song numbers and the respective playing times.

First, a tape cassette is loaded into the tape recorder section 10 so that it can be recorded from the beginning of the A side, and the recording switch 11 is turned on.
Manipulate. However, even when the recording switch 11 is turned on, the reproduction switch 13 is not turned on, so that the tape recorder unit 10 is in a recording standby state. Note that the recording switch 11 may be turned ON at a later stage.

Next, the disc is loaded into the disc player. Then, the disk player reads the index information stored in the lead-in area of the disk by the optical pickup 1 and passes the index information through the servo circuit 2 and the signal processing circuit 3 to the microcomputer, as is well known in the art.
Store it in 16.

After that, the tape recording time is input by the tape length setting switch 15, and then the edit switch 14 is turned ON.

Then, the microcomputer 16 calculates the music number included in the index information, the playing time thereof, and the recording time of the tape (one side).
30 minutes), for example, from 30 minutes of tape recording time,
The performance time is subtracted sequentially from the first song, and the number of songs that exceeds the recording time is checked. In this case, the total playing time of the first to sixth songs is 33 minutes, and the sixth song exceeds the tape recording time. Then, from the 30 minute recording time of the tape, subtracting the total playing time of 27 minutes from the first song to the fifth song, the remaining time within the remaining 3 minutes will be checked to see if there is a song after the 7th song. In this case, the eighth tune of the performance time satisfies the condition.

Therefore, the microcomputer 16 sets the track number to be recorded on the side A of the tape from the first track to the fifth track as shown in FIG.
The music number up to the music number and the music number of the eighth music number are selected, and the contents are stored and displayed on the display unit 12.

Subsequently, the music number to be recorded on the B side of the tape is selected by the same processing as described above. In this case, the song numbers of the sixth, seventh, ninth, tenth, and twelfth songs are selected as shown in FIG. 4, and are stored and displayed in the same manner as described above.

Therefore, the remaining time on the side A of the tape is 1 minute, the remaining time on the side B is 1 minute 30 seconds, and 11 songs can be recorded on both sides A and B of the tape, and the remaining time is 2 minutes 30 seconds.

Next, when the reproduction switch 13 is turned on, the microcomputer 16 immediately sends a recording operation start signal to the tape recorder unit 10 if the recording switch 11 is turned on first, and starts the recording operation, and then performs a predetermined operation. As the time elapses, the servo circuit 2 and the signal processing circuit 3 are instructed to cause the disc player unit to perform a reproducing operation. If the recording switch 11 is not turned on first, the recording switch 11 may be turned on after the reproduction switch 13 is turned on.

The disc player section reproduces the first to fifth songs recorded on the disc, and further reproduces the sixth and seventh songs.
Skip the song and play the eighth song. On the other hand, the reproduced signal is converted into an analog signal by the DA converter 4 and is input to the recording circuit of the tape recorder unit 10, where the A signal of the tape is read.
Will be recorded on the surface.

When the microcomputer 16 detects that the reproduction of the eighth track of the disc has been completed, the microcomputer 16 puts the disc player section in a pause state, sends a high-speed fast-forward signal to the tape recorder section 10, and sets the tape recorder section 10 to high-speed. By switching to the fast-forward state, the remaining portion (1 minute) of the side A of the tape is wound up in a short time, and waste of time is omitted.

In the tape recorder section 10, the A side of the tape reaches the end, the operation of the automatic reverse device switches to the B side recording operation state, and the tape recorder section 10 sends an A / B side classification signal to the microcomputer 16. Then, the microcomputer 16 outputs an instruction signal to the servo circuit 2 and the signal processing circuit 3 so that the optical pickup 1 temporarily stopped at the end of the eighth tune is placed at the beginning of the sixth tune which is the first tune of the B-side recording. The tape is moved to start reproduction of the disk, and dubbing is recorded on the B side of the tape in the same manner as described above.

In the above embodiment, only the song recorded at the end of the A side or the B side of the tape is targeted for adjustment of the remaining time.
If two or more songs are to be adjusted and the combination of songs has a certain width, the remaining time of the tape can be shortened, which is more desirable.

In addition, the present invention is not limited to only the embodiments described above and shown in the drawings, and it is needless to say that the present invention can be appropriately modified and implemented without departing from the gist.

(Effects of the Invention) As described above, according to the present invention, when the recording time of the tape to be used is inputted and editing is instructed, the playing time of each music number and the recording time of the tape included in the traction information of the disk are obtained. Based on the calculation, the combination of the track numbers to be recorded on the tape is automatically selected so that the remaining time on the tape is shortened, and the effective use of the tape can be measured while keeping the remaining time on the tape small. It has practically excellent effects such as an increase in the number of recorded songs.
