The program from (t3) to (B), from time 04) to (t
The program up to 5) is designated as (C), and the program from time (t8) to (t7) is designated as (D).These reservation contents are stored in the storage stage F (22) via the input stage f (21) in FIG. ). Note that the information in No. 8 ml(A) to ([1) is handled here in the form of a TV broadcast channel number. FIG. 6(b) shows the operation of the VTR in the recording mode. That is, sequence control f. Dan (
20 selects the number ml (A) as the signal t' to be recorded at the timing (to) from the output of the memory f stage (22) and the timer (23), and outputs a recording command.

Outputs the command. Thereafter, similar operations are repeated until time (t7) to complete the reserved operation. Note that when the VTR is stopped in scheduled recording mode, the power is turned off to all parts other than those that must continue to operate, such as the recording means (22), timer (23), and sequence control stage f (24).
It is configured to be FF. Figure 7 shows the recorded contents on the magnetic tape (T) at time (t7), that is, at the time when the reservation contents are fulfilled. Programs (A) to (D) are being recorded. [Problems to be Solved by the Invention] The conventional recording/reproducing IA 22 is structured as described above. #S There was a problem in that programs were recorded on the tape-like recording medium in the order in which they were broadcast, regardless of the recording order on the tape-like recording medium L that the author desired. In other words, for example, at the point when the operator performs the reservation operation, the probability that the recorded content will be saved for a long time is determined by the program (C:
)． (A). (D). If the order is (B), that is, among the four programs, group #f (C) has the rII ability to be stored for the longest time, and program (B) has the possibility of being consumed the fastest. If it is on the right, tape note M
Considering the efficiency and convenience of use of fi body, number M
BC). (A). (D). It is desirable to record in the order of (B). This recording order makes the recorded contents of program (B) unnecessary and is very convenient when recording another program (E) in that part. When using a tape, use a program (B) and a different program.
It was necessary to compare the time lengths of program (E) to confirm that the samurai period of program (E) was short, which caused problems such as poor usability and unnecessary recorded content remaining. ．． This invention was made in order to solve the problem as described in L, and provides a recording/reproducing device that can record a plurality of programs on a recording medium L in a deliberately specified order when recording. The purpose is to provide the following. [1,000 Steps to Solve the Problems] The recording and reproducing apparatus according to the present invention is capable of recording at least a tape-like recording medium before recording each program from the reservation contents including the recording order on the tape-like recording medium at the completion point of reservation recording. The feature of 4'F is that the means for calculating the movement length of is y4, and the sequence control of the reserved recording state is performed based on the result of the calculation. [Sakukawa 1 According to this invention, the amount of movement of the tape-shaped recording medium before recording is calculated during the reservation recording period, and according to the calculation result,
By sequentially controlling the reservation recording state through rewinding, urgent forwarding, etc. of the recording medium, the recording order of programs on the recording medium at the time of completion of reservation recording can be managed as arbitrarily specified. ．． [Embodiment of the Invention] An embodiment of the invention will be described below based on the drawings. FIG. 1 is a block diagram showing a schematic configuration of parts related to scheduled recording in a VTR according to an embodiment of the present invention, and in the same figure, (20) to (24) are the same as those in the conventional example shown in FIG. Therefore, they will be given the same symbols and their detailed explanation will be omitted. In Figure 1. (25) is an arithmetic means, and this arithmetic stage F (25) receives the outputs of the input means (2l) and the storage means (22) and performs arithmetic processing according to a predetermined algorithm. The sequence control means (24) also includes a storage means (22).
), calculation means (25). In addition to each output of the timer (23), FG generated from a frequency a generator (@not shown) attached to the motor shaft of the capstan motor (not shown)
Upon receiving the signal, the VTR deck mechanism (not shown)
and REC, STOP. to the electric circuit. ? j sending (hereinafter,
It is configured to output operation mode command signals such as FF), S return (hereinafter referred to as F.RE), etc. Furthermore, 'J! In this case, each means (21) to (2) in FIG.
5) are all built into the microcomputer. Next, regarding the operation of the above configuration, we will explain the flowchart shown in Fig. 2, the reservation details shown in Fig. 3, and the desired magnetic tape.
This will be explained with reference to the recording state of Pool L and the time chart showing the operation at the end of the recording shown in Fig. 4. The flowchart shown in FIG. 2 is based on the notation f stage (2
2), @ calculation means (25), timer (23), and sequence control means (20). Figure 3 (a) shows the reservation contents input by the VTR operator, and the recording The programs (A) to (D) to be tried are shown in Figure 6 (a).
), and in addition to such reservation contents, as shown in FIG. The recording order is Jinrikicho Noh, and in this case, the order shown in the figure is (C). (A) (D) . This is what I entered as if it were to be added to the wish in (B). In addition, (↑a), (Tb), (Tc) in Figure 3 (a)
, (Td) are the respective numbers ffi (A), (B) .
(C). This is the broadcast time length of ([1). Once the scheduled recording status is set, in step (1l) of the flowchart shown in FIG.
Deriving the recording start position of magnetic tape E, FF. REIN
The tape is moved to that position using the function. In other words, the recording start position is derived according to an algorithm that secures an area that is scheduled to be recorded in the future. For example, in the case of Figure 3, the first thing to be recorded is the program (A
), but the recording order on the magnetic tape is number ml (
This is after recording C). In such a case, program (C)
The length of the magnetic tape necessary to record the broadcast (no-it) is derived from the broadcast time length (Tc) of Previously, use FF to move the magnetic tape to {&2t of it. This allows you to select programs that are scheduled to be recorded in the future (
This means that the area for recording C) has been secured. In addition. In a VTR, a capstan motor is used to move the magnetic tape, at least during the scheduled recording period.
Also, at this time, the FFI of the magnetic tape is determined by .
This is an FG signal generated by the FG attached to the motor shaft of the capstan motor.N pulses are generated every time the capstan motor rotates once, and by counting the pulses, the FG signal of the capstan motor is 1
The number of rotations can be detected. The positive movement t of the magnetic tape is detected from the rotational speed of the capstan motor, and the sequence control means (24) outputs a signal for controlling the FFIJ. Next, in step (12), the VTR channel is tuned to program (A). Step (l
In 3), at the special point where the output of the timer (4) coincides with the recording start time (tO) of number ml (A), the sequence control means (24) outputs a recording command. Next, step (1
In 4), the sequence control means (24) issues a stop command at time (t1). That is, as shown in FIG. 4, the VTR has an area of 0~! in which a program (C) scheduled to be recorded later can be recorded. ;L1 is secured first, and when the interval (to) comes, the program (A) is recorded in area sentence l - sentence 2. Continuing, when it is determined No in step (15),
Return to step (1l). Here, the program to be recorded next is program (B), but as shown in FIG. 3, program (D) is to be recorded on the magnetic tape first. Here, using the method described above, group # (D) is recorded in the area. After securing areas 112 to 3, at time (t2), program (B) is recorded in areas 3 to i4. Here, the current position of the magnetic tape is 4, as shown in FIG. 4, but the area of the magnetic tape for the next program (C) to be recorded is J2.0-11. Therefore, turn!
After recording II(B), return to step (11), calculate the amount of tape movement based on the FG signal, and perform RE to the position of sentence 0. Then, at time (t4), the program (C) is recorded in the secured areas 0 to 1. Here, as shown in Figure @3, in step (l1) until gl2 when program (D) is recorded, the magnetic tape is turned to FF [,, and at clock time (t6), program (D) is recorded. Programs reserved as follows (^), (B
)． (C). All of (D) are recorded in the desired state of the magnetic tape as shown in FIG. 3(b), and if YES is determined in step (15), the reserved recording is terminated. In addition, in the embodiment mentioned above, the REC during the reserved recording period
．． Except for RE and FF operation, it is simply written as STOP, but similarly to the conventional example, during this stop period, the memory f stage (22), the calculation means (25), the timer (23), and the sequence control means (
24), etc., may be configured so that the power is turned off except for those parts that must continue to operate. Further, in order to reliably record the reserved program without any omissions, the @ calculation means in the embodiment may record the preceding and following portions of the recorded program for a short period of time. Furthermore, at the end of the reservation input, the calculation means (2
In step 5), we will determine whether or not the reservation details can be realized, and if it is not possible,
If the system is structured so that the operator is informed of this using the display on the operation panel or the TV screen, usability can be further improved. Furthermore, in the above embodiment, it has been explained that all the means shown in FIG. Even if configured by
The same effect as in the seventh embodiment is achieved. Furthermore, in the second embodiment, the case of a VTR was explained. Similar effects can be achieved even when applied to any recording/playback device that uses a tape-shaped recording medium such as DAT. Effect of invention F] As shown in H below, according to this invention, the reservation record can be completed.
The recording order of the tape-shaped recording medium-L can be specified at each point, and the tape-shaped recording medium can be rewound or fast-forwarded according to the reserved content during the reserved recording period, so that the recording order on the recording medium can be specified. The recording order can be arbitrarily set as desired by the operator, the recording medium can be used effectively, and an easy-to-use recording and reproducing device can be obtained.
