Description

[Detailed explanation of the idea] [Industrial application field]

This invention is compatible with compact disc (CD) players, digital audio tape recorders (DAT), and video disc players (VD).
The present invention relates to a composite audio device including a reproducing device in which an absolute address is recorded in recorded information, as typified by , and a recording device, typified by a tape recorder, in which a reproduced signal from the reproducing device is recorded.

[Summary of the idea]

This invention detects the total playback time of the playback device and the total recording time of the recording device, and if the detected total recording time is shorter than the total playback time, the difference time is recorded in the recording device ( This is a composite audio device that separates each song and fades out at equal intervals.

[Conventional technology]

2. Description of the Related Art Conventionally, composite audio devices having a so-called copying function, which records signals reproduced by a reproducing device on a recording device, have been in widespread use. In this case, for example
When copying (recording) songs recorded on a CD onto magnetic tape, if the total playing time of the CD you want to record is longer than the recording time of the magnetic tape, information (songs) that cannot be recorded may occur. There was some information (song) where the last information (song) could only be recorded halfway. Also, if you really want to record all the songs, you have to fade out multiple songs in the middle to control the length of the songs, and this operation was done manually.

[Problem that the invention attempts to solve]

In this way, composite audio devices equipped with conventional playback devices and recording devices sometimes have songs that cannot be recorded, or only halfway through the last song during recording, or even require manual operation. Even if you faded out and shortened the length of each song, there were problems such as the cutting time differing depending on the song, or the recording time of the magnetic tape being left over due to incorrect calculation of the cutting time. . This idea was made to solve the above-mentioned problems with conventional composite audio devices. Even if the total recording time of the recording device is shorter than the total playback time of the playback device, The object of the present invention is to provide a composite audio device that can record information from the device.

[Means to solve the problem]

In order to achieve the above objectives, this invention
In a composite audio device including a playback device in which an absolute address is recorded in recorded information, and a recording device that records a playback signal from the playback device, the absolute address in the recorded information of the playback device is detected for playback and recorded. a reproduction time detection means for detecting the total reproduction time of information; a total recording time detection means for detecting the total recordable time of the recording device; and the total reproduction time obtained by the reproduction time detection means and the recording time. It has a comparison means for comparing the total recording time obtained by the detection means, and a level control means for fading out the reproduction signal of the reproduction device or the recording signal of the recording device, and the comparison means compares the total recording time. If it is shorter than the reproduction time, the difference time is divided for each piece of recording information recorded in the recording device, and the level control means is controlled at equal intervals to fade out.

【Example】

Examples of this invention will be described below with reference to the drawings. FIG. 1 is a diagram for explaining the outline of the main part of this invention. In this Figure 1, the playback device
The total playback time of songs (four songs in the illustrated case) on a CD player is T, and the total recording time recorded on a magnetic tape of a tape recorder, which is a recording device, is t. If the total recording time T of the magnetic tape is shorter than the total playback time t of the CD, if the playback and recording are performed as is, the time (T
-t), it is therefore impossible to record only (T-t)/4 by fading out the playback signal of the playback device (the end of each song) during the copy operation and cutting the end of each song by (T-t)/4. , so that all desired reproduction signals can be contained within the entire recording time of the magnetic tape. FIG. 2 is a block diagram showing the configuration of the main parts of a device according to an embodiment of this invention. In the figure, reference numeral 1 is a CD player, an absolute address is recorded inside, and the playback time of a song is determined from the recorded information. It has lead area detection means for detecting. Reference numeral 2 denotes a tape recorder, which is connected so as to be able to record the playback signal from the CD player 1, and records the recording signal (playback signal from the CD player 1) of the total recording time detection means 2a that can detect and record the remaining tape time. It has level control means 2b for fading out. 3 is
Means for inputting read area information from the CD player 1 to measure the total playback time of songs recorded on the CD, inputting and comparing the total recording time from the tape recorder 2, and recording of the tape recorder 2. Means for controlling pose and level control means 2
This is a tape recorder control means consisting of a microcomputer having means for controlling b. The operation of the composite audio device of this invention constructed in this way will be explained. First, CD player 1 and tape recorder 2
detects the desired number of songs to be copied (for example, 4 songs), the total playback time, and the total recording time that can be recorded on the magnetic tape, and inputs them to the control means 3. The control means 3 compares the total playback time and the total recording time, and if the total recording time is longer, controls the tape recorder 2 to continue the copying operation. If the total playback time is longer, the fade-out time and recording pause time are calculated as shown below, and the tape recorder 2 is controlled accordingly. Here, if the number of songs on the CD you want to record is 4, the total playback time is T, the total recording time of tape recorder 2 is t, and the playback time is F, then the fade-out start time of the first song A ₁ A ₁ = (second song -(T-t)/4-F Recording pause start time of the first song B ₁ (Time to start cutting the song) B ₁ = (Time the second song starts) -(T-t)/4 = A ₁ +F Recording pause release time C ₁ (Start time of 2nd track) C ₁ (Start time of 2nd track) Fade-out start time of 2nd track A ₂ A ₂ = (Start time of 3rd track) −(T-t)/ 4-F 2nd song recording pause start time B ₂ (time to start cutting the song) B ₂ = (3rd song start time) -(T-t)/4 = A ₂ +F Recording pause release time C ₂ (3 C ₂ = (Time when the third song starts) According to the above timing, the level control means 2b arranged on the input side of the tape recorder 2 and the recording pause control of the tape recorder 2 are controlled by the control means 3. It will be done. FIG. 3 is a main part configuration diagram showing another embodiment of this invention, in which the level control means 1a and the control means 3
is shown arranged on the CD player 1 side.
In this embodiment, since the control means 3 is housed in the CD player 1, it performs the same function as the configuration shown in FIG. This has the advantage that playback information can be selected at random. In the above embodiments, a composite audio device consisting of a CD player and a tape recorder has been described. This can be implemented in the same manner as long as it is a playback device that contains absolute address information.

[Effect of the idea]

As described above, according to this invention, by detecting and comparing the total playback time of the playback signal and the total recording time of the recording device from the absolute address recorded in the recording information of the playback device, the recording device or the playback device The fade-out start time of the recording device, the recording pause time of the recording device, the search time of the playback device, etc. are calculated, and the playback signal of the playback device or the recording signal of the recording device is controlled. Even if the total recording time is shorter than the total playback time of the playback device, the last part of each song to be copied is faded out and cut at equal intervals, and the playback signal of the playback device is processed within the recording time of the recording device. can be recorded.
