[Summary of the invention] In the present invention, the reproduction signal of the first recording medium is recorded on the first track when the second recording medium moves in the forward direction and on the second track when the second recording medium moves in the reverse direction. In the recording/reproducing device, the second
detects the end of the first track of the recording medium, and switches the second recording medium from forward movement to reverse movement according to the detection signal;
After cueing the first recording medium to a predetermined position prior to the position corresponding to the detection time point, the recording medium is placed in a paused state, and playback is resumed after a predetermined period of time has elapsed. It is something. By doing so, it is possible to eliminate signal interruptions that occur when the first recording medium changes its direction of movement.

[Conventional technology]

2. Description of the Related Art Conventionally, there have been commercially available recording and reproducing devices in which a CD (compact disc) player and a tape recorder are integrally housed in a single case. This recording and reproducing apparatus can selectively perform reproduction on a disk and recording or reproducing on a magnetic tape, and is also provided with a dubbing function. In the dubbing mode, the disc playback signal from the CD player is supplied to the tape recorder and recorded on the tape.

If the above tape recorder is equipped with an auto-reverse function, the tape is first run in the forward direction to record on the forward track, and when the end of the forward track is detected, the tape is reversed. The recording head is moved to continue recording on tracks in the opposite direction by reversing the direction of travel.

The end of the forward track is detected by optically detecting a transparent leader tape connected to the end of the magnetic portion of the tape.

[Problem that the invention attempts to solve]

When dubbing a plurality of music songs recorded on a disk onto a tape using the dubbing function and auto-reverse function described above, dubbing is performed according to the tape format shown in FIG.

In FIG. 3, a tape 1 is provided with a magnetic body part 2 and a leader tape 3 connected to a terminal end 2a of this magnetic body part 2. First, song A is recorded on the forward track 4 provided on the magnetic body section 2 while moving a recording head (not shown) relative to the tape 1 in the direction of arrow a. When recording of song A is completed, song B is recorded with a predetermined margin 5 left. When the trailing end 2a of the track 4 is detected during recording of song B, the tape 4 is reversed and the recording head is moved toward the track 6 in the opposite direction. This causes the recording head to move relatively in the direction of arrow b, and the remaining portion of song B is subsequently recorded on track 6.

However, in the conventional device, the terminal 2a
After the tape 1 is detected, it takes some time for the tape 1 to be reversed and for the tape 1 to stabilize in the reverse direction. For this reason, when playing back the tape 1 recorded in the above-described manner, sound breaks may occur during playback of song B.

[Means for solving problems]

The present invention includes a playback device that plays back a first recording medium, and a playback signal obtained from the playback device that tracks a first track when the second recording medium moves in the forward direction and a second track when the second storage medium moves in the reverse direction. a recording device for recording on a track; a detecting means for detecting the end of the first track of the second recording medium; and a detecting means for detecting the end of the first track of the second recording medium; a switching means for switching the direction movement; and a switching means for switching the playback operation of the playback device in response to a detection signal from the detection means, and a switching device for controlling the playback operation of the playback device in response to a detection signal from the detection device, and determining a playback start position of the first recording medium by the playback device when the end of the first track is detected. means for moving the playback device to a predetermined position prior to the position corresponding to the point in time to establish a paused state; and means for canceling the paused state and starting playback of the playback device after a predetermined time from the detection signal. It is set up.

[Effect]

When dubbing music, in the example shown in FIG. 3, when the end 2a is detected, the tape is reversed, the CD player pauses, and the beginning of song B on the disc is performed. Then, after a predetermined period of time has elapsed, the pause is released and song B is played from the beginning. Therefore, since the song B is recorded on the backward track 6 from the beginning, there will be no interruption in the sound.

〔Example〕

In FIG. 1, the recording and reproducing apparatus having a dubbing function according to the present invention is provided with a CD player section 7 and a tape recorder section 8.

In dubbing mode, the CD player section 7
Then, the disc 9 is rotationally driven by the player drive section 10, and the pickup 11 performs playback. The reproduced signal from the pickup 11 is applied to the amplifier 14 of the tape recorder section 8 through an amplifier 12 and a switch 13 which is closed during dubbing mode. The output signal of this amplifier 14 is sent to the recording head 1 of the tape recorder drive section 15.
6 and is recorded on tape 1.

When dubbing is performed in this way,
The tape drive unit 15 sends a signal REC indicating that it is in recording mode to a system control circuit 17 comprised of a microcomputer or the like.

Next, the dubbing operation according to this embodiment will be explained with reference to the example shown in FIG.

Song A is recorded on forward track 4, followed by song B.
is recorded with a margin 5 left. When the end 2a is detected during the recording of song B, the tape drive section 15 reverses the running direction of the tape 1 from the forward direction of arrow a to the opposite direction of arrow b.
The recording head 16 is moved in the opposite direction toward the track 6. At the same time, an end detection signal END is sent from the tape drive section 15 to the system control circuit 17. The system control circuit 17 uses the above signal REC and signal END.
Based on the output of the product, a signal is sent to the player drive unit 10 to put the player drive unit 10 into a pause state and to locate the beginning of the song B currently being played on the disc 9. When the cue is completed, the pickup 11 stands by at the beginning of song B for playback.

Then, after the above signal END is obtained, for example 4
When the seconds have elapsed, the pause state of the player driving section 10 and the playback standby state of the pickup 11 are released, and playback of song B is resumed. At this time, the tape 1 has already completed its reversal and is running stably in the opposite direction, and the track B is placed on the reverse track 6 of the tape 1.
is recorded from the beginning. Therefore, song B is continuously recorded on this track 6 until the end. When this tape 1 is played back, the entire song B is played back continuously without any sound interruptions.
When the end of the backward track 6 is detected, the tape drive section 15 is shut off and a stop signal STOP is sent to the system control circuit 17, whereby the player drive section 10 is also shut off. Also, when the player drive section 10 finishes playing all the songs recorded on the disk 9 during dubbing, it is shut off, and in response, the tape drive section 1
5 is also configured to be shut off by the signal STOP.

FIG. 2 is a flowchart showing the operation of the system control circuit 17 in dubbing mode.

In FIG. 2, the dubbing mode is first set in step (1). During the dubbing operation, it is monitored in step (2) whether or not the terminal end 2a or the starting end (not shown) of the magnetic body section 2 is detected.

If the end or start end of the magnetic body portion 2 has not been detected, it is checked in step (3) whether the running direction of the tape 1 has already been reversed. If the running direction of the tape 1 is not reversed, it is assumed that the tape 1 is currently running in the forward direction, and the process returns to step (1) to continue dubbing.

When the terminal end 2a of the magnetic body section 2 is detected in step (2), the process proceeds to step (4). It is checked whether the output operation, auto-repeat operation, etc. are being performed. CD
If the player section 7 is playing, the step will start immediately.
In step (5), the CD player section 7 is put into a pause state, and in step (6), the beginning of the song that was being played when the end 2a was detected in step (2) is performed. Further, in step (7), the timer is set to 4 seconds and the process returns to step (1). If it is determined in step (4) that the CD player section 7 is performing an operation other than a playback operation, the process proceeds to step (8), where the CD player section 7 is immediately put into a pause state, and step (7) is performed. ) to set the timer to 4 seconds and step (1)
Return to

In step (2), the detection signal at the terminal end 2a has already fallen after detection, so the process advances to step (3). In step (3), it is determined whether the running direction of the tape 1 has been reversed based on the detection of the end 2a. If the reversal of the tape 1 is not completed, the routine of steps (1), (2), and (3) is repeated, and when the reversal of the tape 1 is completed, the routine advances to step 9. Here, wait for the timer set in step (7) above to elapse for 4 seconds. When the four seconds of the above-mentioned timer have elapsed, the pause of the CD player section 7 is released in step (10), playback is resumed, and the process returns to step (1).

In addition, if steps (4) and (8) above are omitted,
If the terminal end 2a is detected, the CD player section 7
is performing a cueing operation other than playback, for example, when the cueing operation is completed and playback is started, and then the reversal of tape 1 is finished and recording is restarted, the reverse direction track 6 The beginning of the signal that is recorded to is not recorded, resulting in a truncated beginning. The operations in steps (4) and (8) above are performed to prevent such head-offs.

[Effect of idea]

According to the present invention, when dubbing a block of continuous signals such as a music piece using the auto-reverse function of the recording medium on the recording side, when the moving direction of the recording medium on the recording side is reversed, The problem of sound breakage that occurs can be effectively solved. Therefore, the present invention has a particularly great practical effect when applied to a recording and reproducing apparatus having a dubbing function in which the playback signal of a CD player is recorded by a tape recorder having an auto-reverse function.

In addition, control is provided to temporarily stop only the reproducing device related to the first recording medium in response to the detection signal of the detection means, and to synchronize the second recording medium by simply switching from forward movement to reverse movement. Since the system does not perform any

Furthermore, since the pause state is canceled and the playback device starts playback after a predetermined period of time after the detection signal is obtained, it is possible to stably transfer the sound to the second recording medium without causing sound fluctuations or cut-offs. Recording is possible.

Furthermore, since control by an edit mode switch or the like is not required, recording onto the second recording medium can be performed automatically and inexpensively without requiring complicated key operations.
