Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus for switching tracks by utilizing inversion symbols.

[0002]

2. Description of the Related Art Generally, an information reproducing apparatus such as a CD (Compact Disk) player is used to drive a DCC (Digital Compact Cass).
ette) A reverse marker is used when making a dubbing recording for a recording / playback device such as a recorder. The reverse marker is an inversion symbol and is one of the additional information for operation control recorded together with main information such as music.

This reverse marker is recorded at an appropriate position on a tape such as a DCC tape during recording. And
When the recorded reverse marker is detected at the time of reproducing the tape, the recording / reproducing apparatus reverses the tape running without running the tape to the end of the tape, and the tape is moved in one feeding direction (hereinafter referred to as A side). The control can be transferred from the reproduction to the reproduction in the opposite direction (hereinafter referred to as the B side).

Conventionally, D using the above-mentioned reverse marker
In a recording / reproducing apparatus such as a CC recorder, the user gives an instruction to the recording / reproducing apparatus at an arbitrary position by calculating the playing time of the music recorded on the CD or the like, and puts this reverse marker on the tape. I had to write to.

Further, in a compact cassette tape recording / reproducing apparatus for analog signals, the user inputs the recordable time of the cassette tape in advance, and the apparatus outputs C.
The length of the song is calculated with reference to the performance time information, etc., which is recorded separately from the music information such as D.
It was necessary to sort the songs to be recorded on each side.

[0006]

As described above, in the recording / reproducing apparatus using the reverse marker, the recording of the reverse marker must be performed by the user himself, and the adjustment of the timing has not been automated. Therefore, the user needs to constantly monitor the recording status of the tape during recording, and the recording may fail due to human error.

Further, the recording / reproducing apparatus for a compact cassette tape has the following disadvantages. The user had to set the recordable time of the tape to be used by himself. This is because the compact cassette tape recording / reproducing apparatus has no means for detecting the recording time.

It was not possible to avoid the non-recording portion during reproduction. This is because in the recording / reproducing apparatus for a compact cassette tape, the reversing mechanism does not depend on the reverse marker but is based on the so-called auto-reverse mechanism that detects the tape end point of the tape in use and performs reversal.

There was a break in the recorded music. This is because the unrecordable portion provided at the end portion of the recording tape is inserted in the middle of the song. Therefore, it is an object of the present invention to provide a recording / reproducing apparatus capable of automatically recording music or the like with optimum distribution simply by installing an information source medium and a recording target tape.

[0010]

In order to achieve the above object, a recording / reproducing apparatus according to the present invention has an information piece such as music recorded on a recording medium and a TOC relating to them.
(Table Of Contents) has a reproducing means for reproducing time information, and means for detecting the recordable time of the tape recording medium, and the time information such as TOC and the recordable time information, in the tape recording medium. The present invention is characterized by comprising an arithmetic means for calculating the recording timing information of the inversion symbol and an inversion symbol recording means for recording the inversion symbol based on this recording timing information.

[0011]

According to the present invention, the time information obtained from the reproducing means and the recordable time information outputted from the recordable time detecting means are given to the calculating means. The calculating means calculates the recording timing information of the inversion symbol based on the input time information and the recordable time, and records the inversion symbol on the tape by the inversion symbol recording means at the timing according to the calculation result. , The reverse marker which is the inversion information,
It can be recorded at the proper position on the tape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of the present invention will be described with reference to the drawings. (I) First Embodiment FIGS. 1 to 5 show a recording / reproducing apparatus according to the first embodiment.
In this embodiment, a CD player which is an information reproducing means and a DCC recorder which is a recording and reproducing means are connected by an interface.

As shown in FIG. 1, digital audio information read from the information recording surface of the CD 3 by the pickup 2 inside the CD player 1 is RF (Radio Freq).
uency) Amplifier 4 amplifies and enters a digital signal processor (hereinafter referred to as DSP) 5. Inside the DSP 5, error correction and interpolation of signal components are performed based on the code error correction theory, and converted into error-free digital voice information. This digital audio signal is a digital audio interface (hereinafter referred to as DAI) 6
Through the audio signal line 7 and is supplied to the DCC recorder 8.

Inside the DCC recorder 8, this digital audio signal is supplied to the DSP 10 via the DAI 9. Inside the DSP 10, the digital voice signal is formatted by high-efficiency coding, and the code error correction information derived by calculating the format signal is combined with the format signal to form a recording signal. This recording signal is sent to the head amplifier 11
The data is amplified by, and sequentially switched to eight tracks (not shown) in the head 12 in time and recorded on a DCC tape (not shown).

On the other hand, the T including the time information contained in the CD
There is a flow of OC information. The TOC information includes the lengths of the songs related to the music recorded on the CD for all the songs, and the cue of the songs and the calculation of the remaining time can be calculated based on the TOC information.

This TOC information read from the lead-in area, which is recorded on the innermost circumference of the CD 3, follows the same path as the digital audio signal, and is picked up by the pickup 2, RF.
After being passed from the amplifier 4 to the DSP 5, this time it is taken in and stored in the system control unit 13. The system control unit 13 outputs a control signal to the mechanical unit 16,
This is a place where the player 1 performs servo and the like.

Further, the TOC information stored in the system control unit 13 is sent to the DC via the TOC information line 14.
It is supplied to the C recorder 8. Inside the DCC recorder 8, the system control unit 15 stores this TOC information supplied from the CD player 1, determines the operation sequence and calculates according to the flowchart described later, and calculates the recording timing information of the inversion symbol. . DC
The reverse marker to be stored on the C tape is generated at an appropriate timing according to the recording timing information in which the inversion symbol is calculated, is amplified by the head amplifier 11 via the DSP 10, and a control (AUX) track inside the head 12 is not shown. It is recorded on a DCC tape (not shown).

Further, among the control signals, those related to the control of the mechanical section such as the servo are supplied to the mechanical section 17 at an appropriate timing by the system control section 15, and the mechanical section 1
Reference numeral 7 drives each part.

As shown in FIG. 5, the DCC tape is provided with a detection hole for checking the recordable time. FIG. 5 (a) shows the appearance of the DCC tape. Depending on the presence / absence of holes at the positions of H3, H4, and H5,
The recordable time can be detected as shown in FIG. The system control unit 15 can check this detection hole through the recording time detection unit 18.

Next, the operation of the first embodiment will be described with reference to the flow chart of FIG. The purpose of this flowchart is to distribute the songs so that the total time of the songs recorded on the A side and the B side of the DCC tape is about the same.

First, when the CD player 1 and the DCC recorder 8 are powered on, after proper initialization,
The start mode (S101) of this flowchart is entered. When the CD 3 is loaded in the CD player 1 and the DCC tape is loaded in the DCC recorder 8, the recording preparation state is set (S102).

Next, when the user gives an instruction to start recording, preparation for calculation for recording is started. First, the system control unit 13 of the CD player 1 outputs a control signal to the mechanical unit 16 or the like, the CD 3 rotates, and the TOC information is read from the lead-in area of the CD 3 through the pickup 2. The read TOC information is stored in the system control unit 15 of the DCC recorder 8 through the system control unit 13 (S103).

On the other hand, the system control section 15 reads the detection hole of the mounted DCC tape by the recording time detection section 18 and stores the recordable time of the target DCC tape in the system control section 15 (S).
104).

Next, the initial condition of the CD music to be recorded on the DCC tape is set (S105). This initial condition is set so that the song to be recorded on side A is only the first song of CD3 and all the remaining songs are recorded on side B.

Based on the stored time information, TOC information, the system control section 15 sums up the playing time (T _a ) of the music set on the A side and the playing time of the music set on the B side. (S _b ) is compared with the sum (T _b ). ● When T _a <T _b The playing time on side B is longer. Therefore, the first music set on the B-side (the second music of the CD in the first time) is added to the music on the A-side (S107), and the calculation of S106 is performed again for comparison. This repetition continues until T _a ≧ T _b . ● In the case of T _a ≧ T _{b It} is considered that when the total playing time of the A side becomes equal to or more than the total playing time of the B side, both times are almost equally distributed to the A side and the B side. In this case, the sum T _a playing time of the A side is the same as or total playing time of at least B surface, or longer.

[0026] Thus, the sufficient length of recording time to record a T _a, as long as it has the one surface of the DCC tape of interest, it is determined that can record all songs CD3. Therefore, the recordable time of the target DCC tape (S104
Recordable time of one side ( _Tr )
And the total sum (T _a ) of the playing times of the pieces of music on the A side finally set in S106. ● In this case the case of T _r ≦ T _a, the recording time of one side of the DCC tape, A
Same or less than the playing time of the surface. Therefore, it is determined that the target DCC tape is partially insufficient, and the recording preparation is canceled (S109). Then, by displaying something or the like, the user is prompted to mount a tape having a longer recording time (S110), and when the tape is mounted, the recording preparation state (S103) is resumed. T _r is T _a
Even if the length is equal to, consider the length of the non-playing part between songs, and process at this stage with a margin. ● In case of T _r ＞ T _{a In} this case, it is possible to record all songs with plenty of time.
Recording is started (S111). While this recording is being performed, it is checked at an appropriate interval whether or not the last piece of music set on the side A has ended (S112).

If it is not completed (NO), check again with some time. When the end is confirmed (YES), the system control unit 15 immediately outputs a control signal to the reversing mechanism of the mechanical unit 17, reverses the tape running direction, and switches the scanning track (reverse) (S113).

When the reversal is completed, the system control section 15 records the temporary reverse marker on the B side through the AUX track of the head (S114). After that, record up to the last song set on side B (S1
15).

Finally, by rewinding this tape, B
The reverse marker is renumbered (re-recorded) at the portion of the surface A that has been hit immediately before the temporary reverse marker recorded on the surface (the moment the reverse operation of S113 starts) (S
116), all recording is completed (S117).

The reason for using the temporary reverse marker as described above is as follows. The blank time between songs on a CD is usually small. On the other hand, the mechanical operation such as half rotation of the head and reversal of the running direction of the tape is usually longer than the judgment time of the electric system.

Therefore, the system control unit 15
When it is judged that the mechanical section 17 should be reversed (YES in S112), it must output a control command to the mechanical section 17 as soon as possible to instruct the mechanical section 17 to immediately perform the reverse operation.

The temporary reverse marker is the mechanical unit 1.
It is sufficient to wait for the end of the reversing operation of No. 7 and record at the beginning of the first music piece on the B side at the same time when the reversing operation ends. The original reverse marker for instructing the inversion operation at the time of reproduction may be rewritten at the end point of the last tune on the side A after the end of recording with reference to the position of the temporary reverse marker.

It should be noted that the work of writing from the temporary reverse marker to the reverse marker (S116) does not have to be carried out continuously as the last step of recording as in the present embodiment, but is independent as a later work. It may be performed by any procedure such as performing it as an operation or performing it during the subsequent reproduction.

FIG. 3 shows the states of the reverse marker and the temporary reverse marker. As shown in FIG. 3A, the reverse marker is a kind of sector marker and has a length of 32 frames in DCC. The repetition of 4 frames is a mark of a sector marker. Various markers such as the reverse marker are L-ID (Label-ID) and SCM-I in the figure.
It is configured by various combinations of D (Sector Marker-ID).

FIG. 3B shows a temporary reverse marker. As shown in the figure, it is written in the first part of the track on the B side, and by a later operation, it is written as a reverse marker as shown in FIG.

FIG. 4 shows an example of reverse marker recording in the first embodiment. This is an example of recording according to the present embodiment. As shown in the figure, in this recording example,
11 songs are recorded on the CD, total playing time is 52 minutes 3
7 seconds. When this embodiment is applied to this, as shown in the figure, 6 pieces are recorded on the A side of the DCC tape, and the time is 26 minutes and 22 seconds.
It can be seen that the remaining 5 songs on the B side, which are 26 minutes and 15 seconds in time, were recorded, and are distributed almost every half of the total time of the CD.

As described above, according to the first embodiment, the DC
The songs on the CD are automatically recorded on the C tape with almost equal time distribution. In this embodiment, a music source such as a CD can be recorded on the A side and the B side in an evenly balanced manner.
This is suitable for recording one sheet on one DCC tape. (II) Second Embodiment FIGS. 6 and 7 show a recording / reproducing apparatus according to a second embodiment of the present invention. The present embodiment is a system in which as many songs as possible are recorded on the A side and the remaining songs are allocated to the B side in the same hardware configuration as the first embodiment.

The operation of the second embodiment will be described with reference to the flowchart of FIG. The power of the entire apparatus is turned on, the necessary initialization is completed (S201), and the recording preparation state is entered (S202). The system control unit 15 is the first
As in the embodiment, the TOC information is instructed to be read from the CD (S203), and the recordable time of the DCC tape is detected (S204).

Next, the recordable time T _DCC of the DCC tape
And the total playing time T _{CD of CD} are compared and examined. ● In case of T _DCC ≤T _{CD In} this case, all the songs on the CD cannot be completely recorded on the DCC tape to be recorded. Therefore, the recording preparation for this DCC tape is canceled (S206), and a message etc. is displayed to the user. The tape change is urged (S207), and the state returns to the recording preparation state (S202). ● When T _DCC > T _CD Recording is started (S208). During recording, at a suitable timing, whether the song that was playing at that point ended,
Continuously monitor (S209). If not finished (N
O) again repeats the same steps with a delay.

When the performance is completed (YES), the remaining time (T _l ) of the A side is calculated based on the recordable time of the DCC tape (S210). Furthermore, TO
The playing time (T _n ) of the next piece of music obtained from the C information is compared with the remaining time T _{l on} the A side. ● When T _n ≤ T _l The remaining time is longer than the next song, so the next performance starts (S
212). Then, S20 for monitoring the end of performance of the next song
Repeat step 9. When T _n > T _{l Since} the remaining time is not enough to play the next piece of music, a reverse operation is performed here (S213). After that, as in the first embodiment, the temporary reverse marker is recorded (S214), and the B side is recorded up to the last song (S21).
5). Once the recording is finished, the original reverse marker is renumbered at an appropriate time (S216), and all the work is finished (S217). The reason why the reverse operation is started without recording the reverse marker in S213 is the same as in the description of the first embodiment.

FIG. 7 shows an example of reverse marker recording in the second embodiment. This example is the first described in FIG.
The second embodiment is applied under the same conditions as the reverse marker recording example of the embodiment. As shown in the second
In the example, the song is recorded on the A side as much as possible,
In this recording example, there are 7 songs on A side, 29 minutes 03 seconds, and 4 on B side.
The song was recorded for 23 minutes 34 seconds.

As described above, according to the second embodiment, it is economical that the songs can be packed without waste and recorded, and it is suitable for the case where it is desired to record another song on the remaining unrecorded portion of the B side. Is.

Each of the above embodiments can be modified in several ways as shown below. In each of the above embodiments, as shown in FIG. 1, the CD player 1 and the DCC recorder 8 are separated into a single unit, but it is also possible to operate them as an integrated device.
