Abstract

PURPOSE:To perform dubbing without generating the interruption of music by rewinding a magnetic tape to a music head and erasing the recorded part of music from a music play starting position in case of detecting the end of the magnetic tape and also the fact that music is being reproduced. CONSTITUTION:The music of a music source 1 is reproduced at a reproducing device 2, and the dubbing of the music on the magnetic tape of a recorder 3 is performed. When the end of the magnetic tape is detected by a first detecting means 4, a control means 7 receiving the detecting signal retrieves the output of a second detecting means 5, and judges whether or not the music source 1 is performing the reproduction of the music. And when the music is being reproduced, the magnetic tape is rewound to the recording start position of the music stored in a storage means 6, and the magnetic tape is fed again, then, the recorder 3 is controlled so as to erase recorded music. In such a way, it is possible to perform the dubbing without generating the interruption of the music.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a magnetic tape end processing device in a dubbing device or the like.

``Prior Art'' Traditionally, tape recorders have been used as dubbing devices for music sources composed of multiple songs such as LP records, and the recording times of recording tapes vary depending on the playing time of the music source. is widespread.

For example, an LP consisting of 20 minutes per side as a music source.
When dubbing a record, if you prepare a magnetic tape of 23 minutes per side, the recording will be completed before the magnetic tape finishes recording.
Since the playback of the LP record ends, the recorder can reliably record one side of the LP record onto the magnetic tape, and the unexpected situation where the magnetic tape ends in the middle of the song can be avoided.

``Problems to be Solved by the Invention'' However, when dubbing is performed using a conventional dubbing device, the recorder is required to perform an operation to match the music source performance time and tape recording time as described above.

Furthermore, if the music source performance time and tape recording time do not match, the recorder must monitor the recording status.

Therefore, the recorder is constrained in his or her actions when recording, and if monitoring 1 is neglected, the music at the end of the tape may be recorded half-heartedly. In addition, when dubbing a music source that has many songs recorded on only one side, such as compact discs (CDs) that have become popular in recent years, the recording time of the magnetic tape is shorter than the playing time of the music source. As a result, erroneous recordings such as those described above are becoming more likely to occur.

In addition, as such conventional technology, the actual playback time of program information in an information playback section of a disc playback device, etc.
There are devices that compare the remaining recording time of the recording medium in the information recording section of a tape recorder, etc., and display a predetermined display or control the information playback section or the information recording section according to the comparison result ( For example, JP-A-58-16
1189, etc.). In this conventional technology, when recording the playback output of program information in the information recording section in the information playback section, the time required to play back each program information is compared with the remaining recording time of the recording medium in the information recording section. When the recording time becomes shorter than the time required for playback, a predetermined display is displayed and the recording operation of the information recording section is stopped, or the recording medium in the information recording section can be stored within the remaining recording time and there is no recorded data yet. This is a device that dubs onto a recording medium by obtaining reproduction output of program information that has not yet been recorded and performing controls such as recording it.

However, according to this conventional technology, the remaining time on the playback side and the recording time on the recording side are constantly monitored, the data at each time is compared, and the playback or recording side device is controlled based on the comparison output. Since it is controlled by means such as stopping, there is a problem that the configuration becomes complicated. Furthermore, when dubbing is performed using a playback device that outputs only a music signal without time information, there is a problem in that the recording ends in the middle of the music.

In addition, as a technology developed by the applicant earlier, there is a dubbing device that records information from a recording medium such as a digital audio disk to a recording medium such as a tape recorder (Japanese Patent Application No. 60-3748). ). This device detects the time information of the program played by the recording medium of the playback device, detects the remaining amount of the recording medium of the recording device, compares the time information of the program with the remaining amount, and If the remaining amount of the medium is less than the playback time of the program to be played from now on, at least one of the playback device and the recording device must be stopped or paused. Since the recording time is monitored and the reproduction side and recording side devices are controlled to stop or the like based on the comparison output, the structure becomes complicated.

In addition, there is a well-known technique for detecting the end of a magnetic tape in a recording/playback device to search for the beginning of a song (for example, Japanese Patent Laid-Open No. 47-16109, Japanese Patent Laid-Open No. 48-5
880.5, etc.). However, these well-known techniques
Both methods search for the beginning of a song by detecting unrecorded parts between songs, and are different from the technical problem that the present invention aims to solve, and are not an essential requirement of the present invention. .

"Means for Solving the Problems" The present invention aims to solve the above-mentioned drawbacks, and provides a magnetic tape recording device for dubbing music played by a playback device onto a magnetic tape, and a magnetic tape recording device. a first detection means for detecting the end; a second detection means for detecting whether the music source is playing a song or playing between songs;
When the end of the magnetic tape is detected by the second detection means and the second detection means detects that a song is being played, rewinding the magnetic tape to the beginning of the song;
To provide a tape end processing device that eliminates the need for monitoring the playback or recording time on either the playback side or the recording side and enables dubbing without song breaks by erasing the recorded portion of the song from the song performance start position. The purpose is to.

"Embodiments" The present invention will be described below based on embodiments of the drawings. The drawing is a block diagram showing a tape end processing device according to the present invention.

In the above drawings, 1 is a music source on which a plurality of songs are recorded, such as an LP record, 2 is a playback device that plays the songs of the music source 1, and 3 is a recorder of the songs played by the playback device 2. In the magnetic tape recording device, 4 is a first detection means for detecting the end of the magnetic tape. 5
is a second detection means, which detects whether the music source 1 being played by the playback device 2 is playing a song or between songs. For example, in the case of a CD, the user's bit is detected. For P-channel and analog sources, this is an input level detection circuit in a comparator. Reference numeral 6 denotes a storage means for storing the recording start position of the magnetic tape, and is composed of, for example, a rotation counter of a tape reel motor, or a clock circuit and a memory element for storing the same. Reference numeral 7 denotes a control means for controlling the recording device 3 to process the end of the magnetic tape using the first detecting means 4, second detecting means 5, and storage means 6 described above.

"Action of invention" Next, the operation of the above embodiment will be explained.

Music from a music source 1 is played back by a playback device 2 and dubbed onto a magnetic tape in a recording device 3. Now, when the first detection means detects the end of the magnetic tape, upon receiving the detection signal, the control means 7 searches the output of the second detection means 5 and detects the music source 1. is currently playing music. When a song is being played, the magnetic tape is rewound to the recording start position of the song stored in the storage means 6, and the magnetic tape is run again to erase the recorded song. Recording device 5
control.

In the above embodiment, a case was explained in which the partially recorded portion is erased independently, but if the recording device 3 is capable of reciprocating recording, the partially recorded portion may be erased on the outward or return trip. The work may be configured to be performed simultaneously with the recording work on the return trip or the outward trip.

Also, in this case, the same effect can be obtained by adding a function to control the music playback device so that the songs recorded on the way back or on the way back are re-recorded on the way out or on the way back. , more effective recording can be performed.

Further, the playback device and the recording device in the present invention do not need to be integrated; for example, the playback device is a playback device that includes the second detection means, and the recording device includes a control device that includes the first detection means. The same effect can be obtained even if the storage means and the control means are built into the recording device.

"Effects of the Invention" As shown above, the present invention includes a magnetic tape recording device 3 for dubbing music played by the playback device 2 onto a magnetic tape;
a first detection means 4 for detecting the recording end of the magnetic tape;
A second detecting means 5 detects whether the music source 1 is playing a song or playing between songs, and the first detecting means 4 detects the end of the magnetic tape, and the second detecting means 5 When it is detected that a song is being played, the magnetic tape is rewound to the beginning of the song, and the recorded portion of the song is erased from the starting position of the song.

Therefore, there is no need to monitor the playback or recording time on either the playback side or the recording side, and only the recording side is equipped with a means for detecting between songs, a means for detecting the end of the tape, and a means for detecting whether the music source is in the middle of a song. By having this, it is possible to dub songs without any breakage.
