Abstract

PURPOSE:To remarkably improve unpleasant feeling on a user and a troublesome operation by rewinding a recording medium automatically to the forefront of a recording block where recording is interrupted when the recording medium at a dubbing side arrives at termination before the recording of a recording content is completed. CONSTITUTION:A master deck 1 converts a digital signal recorded on the recording medium to a voice signal. A display device 4 displays desired information at that time. A dubbing deck 2 is provided with a CPU, and when a cassette tape arrives at the termination in performing dubbing, the CPU judges that the interruption of music is generated if a signal existance state is shown by a no signal part detecting means, and issues a command to rewind the tape to a deck mechanism, and also, displays the interruption on the display unit 14, and stores the identification information of the music. Rewinding is stopped when a no signal part, that is, the program searching part of the music is detected. Therefore, it is possible to recognize the music in which the interruption is generated and the forefront part of the music and to respond to that immediately.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a recording and reproducing system for reproducing a digital recording medium on which a recording block consisting of, for example, audio information is recorded, and dubbing the recording block to another recording medium. Regarding.

[Prior Art] In recent years, in the field of audio equipment, in addition to conventional analog recording media, CDs (compact discs)
2. Description of the Related Art Digital recording media typified by DAT (digital audio tape) have become widespread.

These digital recording media are characterized by the ability to produce playback output that is extremely close to the original sound with extremely little distortion or attenuation, but they also have a subcode area that can record control information separately from audio information. , - The time required to reproduce each recording block consisting of audio information recorded on the recording medium is written in the membrane.

Among the above-mentioned digital recording media, CD playback devices have poor vibration resistance, and CDs themselves are susceptible to dirt and dust. Therefore, users prefer using DAT or cassette tapes rather than purchasing portable CD playback devices. There is a strong tendency for people to dub the audio information recorded on a CD and listen to it on a portable tape player.

In order to respond to this trend, audio recording and playback devices that house a (recording) and playback device for digital recording media such as CDs, a recording and playback device for dubbing, and even a playback amplifier and a speaker are being developed. being developed.

[Problems to be Solved by the Present Invention] When attempting to dub audio information recorded on a CD or DAR to a cassette tape, the end of side A may be reached during the performance of the song. In that case, when the cassette tape is played back, the playback ends in the middle of the last song, which makes the listener feel uncomfortable.

In addition, dubbing ends without being completely dubbed for the song whose dubbing was interrupted and the songs recorded after that point. With conventional devices, when dubbing is interrupted, there is no way to notify the user that dubbing has been interrupted, or which song dubbing was interrupted during. You will know. Also,
It is very difficult to investigate at which song the song was interrupted when listening for the first time.

[Structure of the Invention] (Means for Solving the Problems) The apparatus of the present invention includes a reproducing means for reproducing a digital recording medium on which a plurality of recording blocks are digitally recorded, and an output signal of the reproducing means to another recording medium. A recording means for recording; a means for detecting the end of the other recording medium; and a means for detecting a no-signal portion formed on the other recording medium.

means for detecting application of the reproduction signal to the recording means; memory means; identification information of the recording block being reproduced by the reproduction means when receiving the outputs of the termination detection means and the reproduction signal application detection means; and a control means for writing into the memory means and operating the no-signal portion detection means.

(Function) When a recording block recorded on a recording medium is being recorded on another recording medium and the end of the other recording medium is detected, the control means which has been connected to the end detection signal and the reproduction signal detection signal, Information identifying the recording block whose recording has been interrupted is stored in the memory means, and the no-signal portion detection means is operated to cue the recording block recorded on another recording medium.

(Embodiment) FIG. 1 is a schematic diagram of an embodiment of the present invention, in which 1 is a master deck which is a sound source, 2 is a dubbing deck for dubbing the audio signal output from the master deck 1 onto a recording medium, 3 is an amplifier, 4 is a speaker, 27 is an earphone jack provided in the amplifier 3, and 28 is an earphone that can be connected to the earphone jack 27.

FIG. 2 is a block diagram showing the structure of the master deck 1, and FIG. 3 is a block diagram showing the structure of the dubbing deck 2.

In the following explanation, the master deck 1 will be explained as a CD player and the dubbing deck 2 as a cassette tape recorder, but it is also possible to use a DAT recorder as the master deck 1.

The master deck 1 includes a head 6 that reads a digital signal recorded on a recording medium (CD) 5, a preamplifier 7 that amplifies the signal, and a signal processing unit that performs processing such as error correction of the amplified signal and change of the number of bits. 8. D/A converter 9 that converts the processed digital signal into analog
, converts the digital signal recorded on the recording medium 5 via the main amplifier 10 into an audio signal.

On the other hand, the signal processing unit 8 controls the operation of the CD mechanism 11 for discarding the recording medium and shifting the head, and operates the operation button 1.
The functions corresponding to the operations in step 2 are set, the information stored in the RAM 13 is read and rewritten, and the desired information is displayed on the display 14.

Next, the configuration of the dubbing deck 2 will be explained.

The control signal output from master deck 1 is sent to CPU 1.
5 is input. The CPU 15 includes a timer, a RAM, etc., and is connected to the operation buttons 16 of the dubbing deck 2, and controls various functions according to the operations, and outputs desired control information to the master deck 18.

Further, the CPU 15 is connected to the deck mechanism 17, and controls the running state of the deck mechanism 170 based on the operation of the operation button 16, while also controlling the tape end detection means 18 connected to the deck mechanism 17, and the performance such as single-sided play, double-sided play, endless play, etc. It is also connected to performance mode setting means 19 for setting the mode, and exchanges information.

The audio signal output from master deck 1 is output from terminal 29.
．． Dubbing is recorded onto the cassette tape 20 by the magnetic head 23 via the adjustment amplifier 22. At the same time, the signal is transmitted from the main amplifier 3 to the speaker 4 or earphone 28 via the adjustment amplifier 22, tone control circuit 23, balance control circuit 24, electronic volume 25, and muting circuit 26, and is output as audio. on the other hand,
The audio signal recorded on the cassette tape 20 is also output as audio via the magnetic head 23 and the adjustment amplifier 22 in the same manner as described above, but the audio signal is also sent from the adjustment amplifier 22 to the no-signal portion detection means 21.

The no-signal portion detection means 21 monitors the output signal from the adjustment amplifier 22, and detects the output signal from the adjustment amplifier 22 for a predetermined period of time or more (for example, 5 seconds or more in the normal running mode, or 0 in the fast forward/rewind mode).
．． 05 to 0.2 seconds or more), if the no-signal state continues, a detection signal is output to CI'''U15 as a no-signal portion.

Next, the operation will be explained.

FIG. 4 is a flowchart showing an example of the operation of the CPU 15.

During the dubbing operation, the music recorded on the recording medium 5 is played back, and the played audio signal is transmitted to the adjustment amplifier 22 and magnetic head 23 of the dubbing deck via the terminal 29.
Recording is performed on the cassette tape 20 which is opened and activated to record. At this time, the CPU 15 detects that it is in the recording mode and monitors the output signal of the tape end detection means 18.

When the cassette tape reaches the end, tape end detection means 1
When the detection signal is output from the CPU 15, the CPU 15 checks the output of the no-signal portion detection means 21. If the output of the no-signal portion detection means 21 indicates a no-signal state, that is, if the reproduction signal of the recording medium 5 has not already been transmitted to the adjustment amplifier 22 from the terminal 29, the CPU 15 detects the music at the end of the cassette tape 20. It is determined that there has been no interruption in dubbing, the recording (dubbing) mode is canceled, and the operation is terminated.

When the cassette tape reaches the end, if the output of the no-signal portion detection means 21 indicates a signal state, the CP'U
15 determines that dubbing of a song has been interrupted at the end of the cassette tape 20, and instructs the deck mechanism 17 to rewind the cassette tape 20, while outputting a control signal to the signal processing unit 8 to identify the interrupted song. R information
It is stored in the AM 13 or the RAM in the CPU 15. The above-mentioned identification information is, for example, a serial number recorded on the recording medium 5 and assigned to each piece of music.

Further, the CPU 1.5 causes the display 14 to display that dubbing has been interrupted.

When the no-signal portion detecting means 21 detects a no-signal portion while the cassette tape is being rewound, the CPU 15 stops the operation of the deck mechanism 17.

As a result of the above, the user acknowledges that there has been an interruption in dubbing.
Since you can automatically know which song dubbing was interrupted and the beginning of the song where dubbing was interrupted, you can erase the interrupted song or copy it to one side of the cassette tape (hereinafter referred to as side A). Songs that could not be dubbed can be dubbed onto the opposite side (hereinafter referred to as side 8).

FIG. 5 is a flowchart of the CPU 15 showing a second embodiment of the present invention.

In this example as well, when the tape end is detected! I! +
The series of operations of detecting that the amplifier 22 is in the multiplier state, rewinding the cassette tape 20, detecting a no-signal portion, and ending the rewinding are the same as in FIG. 4.

However, after the above-mentioned rewinding is completed, that is, after searching for the beginning of the song whose dubbing was interrupted, the CPU 15 causes the deck mechanism 17 and the adjustment amplifier 22 to perform a muting recording operation, regardless of whether or not the reproduction signal of the recording medium 5 is transmitted to the terminal 29. command. As a result, the song recorded at the end of the cassette tape 20 whose dubbing was interrupted is erased.

When the tape end detection means 18 outputs a detection signal, the CPU 15 stops the muting recording and completes the entire operation.

According to this embodiment, as in the embodiment shown in FIG. 4, the user can automatically know that dubbing has been interrupted and which song the dubbing has been interrupted, and furthermore, the partially recorded song can be erased. Since the tape is recorded and stopped at the end of the tape, the user does not have to erase it later, and can immediately dub the songs that were not recorded on the first side from the beginning of the B side.

FIG. 6 is a flowchart of the CPU 15 showing a third embodiment of the present invention.

As is clear from the figure, if there is an interruption in dubbing,
The series of operations for starting muting recording from the beginning of the interrupted music piece is the same as the embodiment shown in FIG. However, in this example, when the tape end is detected during 9-muting recording, the CPU 15
7 to reverse the tape running direction, cancel muting, read out the identification information stored in the RAM, and play the interrupted song recorded on the recording medium 5 via the signal processing unit 8 from the beginning. let Thereby, dubbing can be performed from the beginning of the B side of the cassette tape 20, starting from the beginning position of the interrupted song.

Then, the CPU 15 again monitors the output of the tape end detection means 18, and when the tape end is detected, detects the presence or absence of a signal input. If there is no signal input, all operations are completed, but if there is a signal input, the identification information of the interrupted song is stored again, and muting recording is performed from the beginning of the interrupted song.

However, this time, it is detected that the tape is on the 8th side, and the operations after reversal are canceled.

According to the third embodiment described above, the user no longer needs to perform any operations after dubbing starts, and can automatically dub as many songs as can be recorded on both sides of the cassette tape without interruption. Songs that have been played are automatically deleted, so they won't be jarring when played.

In addition, when a song recorded on a recording medium cannot be completely dubbed even with both sides of the cassette tape, re-dubbing to side A of the tape is prohibited, and the identification information of the interrupted song is memorized and displayed. Therefore, there is no risk of mistakenly erasing the music dubbed on side A of the cassette tape.

[Effects of the Invention] As described above, according to the present invention, during dubbing recording, if the dubbing side recording medium reaches the end before the recording content ends, the recording block where dubbing was interrupted is Since the recording medium is configured to automatically rewind to the beginning, there is no need for the user to perform any troublesome operations.
Furthermore, the discomfort experienced by the user due to interruption of dubbing can be largely alleviated.
