Abstract

PURPOSE:To effectively edit in sound recording of plural pieces of music by speeding up a reproducing speed of a compact disk player, compressing plural pieces of programed music in time and recording them when a recordable time on the side of tape is shorter than a reproducing time for the plural pieces of music on the side of a compact disk. CONSTITUTION:A reproducing speed variable circuit of the compact disk player consists of a microcomputer 1, an output part 2, a switching transistor 3, a disk rotating control circuit 4, a quartz oscillator 5 and load capacitors 6-8. Then, prior to the editing sound recording of a regenerative signal f the compact disk to the tape, time for each individual piece of music to be recorded is integrated and compared with the recordable time of the tape, and based on this compared data, the reproducing speed of the disk is promoted by the reproducing speed variable circuit, thus reproducing the individual pieces of music after their time compression. By this method, plural pieces of music can effectively edited in sound recording under reduced residual vacant time on a tape.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a novel recording method for recording a playback signal from a compact disc player onto a tape recorder.

(B) Conventional technology Generally, when recording the playback signal of a compact disc player onto a tape recorder, it is necessary to record as many songs as possible on the tape and to prevent the songs being recorded from being interrupted at the end of the tape. The method used is to select the order and titles of the songs on a compact disc and record them.

These operations are automatically executed by a microcomputer built into the device.

That is, by inputting the time length information of the tape to be used into the device in advance, the device automatically selects the song and records it, which is informally called editing recording.

An example of this editing/recording operation will be briefly explained.

First, input the time length information of the tape to be used into the device.

Next, select the order of the songs to be recorded on the tape from among the multiple songs recorded on the compact disc to be recorded as necessary.
Enter the track information into the device. These operations are generally called program operations.

The built-in microcomputer accumulates playback time according to the programmed song order and track number, or if no programming is done, starting from the first track on the compact disc.
After confirming that this accumulated time does not exceed the recordable time length of one side of the tape, recording is started sequentially.

If the cumulative time exceeds the recordable time on one side of the tape, the microcomputer will not record that song, and will select a playback time from among the unrecorded songs that does not exceed the recordable time on one side of the tape. The system searches for the song title and starts recording. However, if there is no corresponding song, the remaining part of the tape is left blank, and the tape is automatically reversed to record the remaining songs on the other side of the tape. There is.

By recording in this manner, it becomes possible to record the songs without interruption at the end of the tape.

(c) Problems to be Solved by the Invention When recording as described above, for example, if there are 4 minutes of recordable time left on the tape, but there are no songs of 4 minutes or less left on the compact disc. However, there was a problem in that the remaining four minutes of the tape were blank.

(d) Means for Solving the Problems In view of the above-mentioned problems, the present invention provides a recording method for recording playback signals from a compact disc player onto a tape recorder. Accumulate the playback time for each song in the order of , until it exceeds the recordable time on one side of the tape, and compare the time that exceeds the recordable time on one side of the tape with the preset time, When this excess time is less than or equal to the set time,
An editing recording method characterized in that editing recording is started by increasing the playback speed of a compact disc player within an allowable range, and a plurality of songs related to the above cumulative time are recorded within the time of one side of the tape. This is what we propose.

(e) Effect: According to the editing recording method of the present invention, prior to editing recording, a plurality of songs recorded on a compact disc are recorded one by one in order.
Add up the playback time for each song until it exceeds the recordable time on one side of the tape, and compare the time that exceeds the recordable time on one side of the tape with a preset time, and calculate the excess time. When the time is less than the set time, the playback rate of the compact disc player is increased within the permissible range and editing recording is started, so that multiple songs related to the above cumulative time are recorded within the time of one side of the tape. If the available recording time on the tape is somewhat shorter than the playback time of multiple tracks on the compact disc, the playback speed of the compact disc player is increased by the amount of time that is shortened, and the multiple programmed tracks are time-compressed. It acts as if it were to be recorded.

(f) Example Embodiments of the present invention shown in the drawings will be described below.

FIG. 1 shows a flowchart of the present invention, and FIG. 2 shows a variable reproduction circuit for a compact disc player.

The flowchart in FIG. 1 shows the part of the editing/recording operation that is related to the present invention. When the recording start operation is performed, the microcomputer first plays back a plurality of songs recorded on a compact disc one by one in order. Step 1) Add up the time. Repeat the integration until the total exceeds the recordable time on one side of the tape. Step 2) Set in advance the time that exceeds the recordable time on one side of the tape. (step 3), when this excess time is less than or equal to the set time,
The playback speed of the compact disc player is increased by about 2% within the allowable range (step 4), and editing and recording is started (step 5). Step 6: If the excess time exceeds the set time, reduce the number of recorded songs by one.
), the editing recording is started by step 5.

The preset time (for example, 36 seconds) is within the playback tolerance range ± the standard for compact disc players.
This is the time compressed by a 60-minute tape when the regeneration rate is increased by 2%, which is half of 4%.

In FIG. 2, a case will be explained in which the reproduction rate of the compact disc player is increased.

When the microcomputer (1) increases the regeneration rate, it outputs a low level signal from the output port (2), and this signal causes the switching transistor (3) to become non-conductive.

The degree of regeneration is determined by the crystal oscillator (5) that serves as a reference for the disk rotation control circuit (4) and its load capacitances (6), (7), and (8), so the switching transistor (3)
) becomes non-conductive and the load capacitor (8) for frequency adjustment is released from the load capacitor (7), and as a result, the oscillation frequency of the crystal oscillator (5) changes and the regeneration becomes the standard. It operates to increase the speed by 2%.

Therefore, a plurality of songs recorded on a compact disc can be time-compressed and edited and recorded within the recordable time of the tape.

(g) Effects of the Invention As described above, according to the editing and recording method of the present invention, prior to editing and recording the playback signal of a compact disc onto a tape, it is possible to record the tape by adding up the time of each side to be recorded. Based on the comparison data, the playback rate of the disc is increased and the time is compressed to play each side, reducing the remaining blank time on the tape as much as possible and playing multiple songs. This allows for effective editing and recording.
