One end of the video head 71A is connected with a preamplifier 83 that amplifies the signal to a predetermined level.

On the other hand, referring to the operation of the conventional VCR system having the above configuration, first, if the user wants to execute the reservation recording function, for example, the user loads the video tape 70 and manipulates the key input unit 80. The reserved recording time of the tape 70 is set. Then, the microcomputer 77 recognizes the memory and checks the reservation recording time. When the reserved recording time is reached, the microcomputer 77 inputs an operation control signal to the mode switch 76 and the drum motor driver 74. Then, the drum motor driving unit 74 drives the drum motor 73 at the set rotation speed in accordance with the operation control signal of the microcomputer 77. Thus, the head drum 72 interlocked with the drum motor 73 is rotated, and accordingly, the head 71A installed on the head drum 72 is mounted on the tape 70, for example, a tuner (not shown).

Then, the information signal of the tape is processed through the audio signal processing unit 79 and the image signal processing unit 78 into a predetermined signal and then displayed through the display 81 and the speaker 82.

However, since the conventional VCR system as described above is used only as a simple function of recording only when the recording function is set, the multifunctionality of the system, for example, is provided with a function to inform the user of the recording information currently recorded on the tape 70. Therefore, the versatility of the system is deteriorated accordingly, and when several people execute the reserved recording function on one tape 70, the contents of the tape 70 are scanned through a complicated key operation to check the contents. There is a problem in that it is inconvenient to use because it must go to the recording position.

Therefore, the present invention was invented to solve the above problems, and when the video tape is recorded, the recording information of the video tape is sequentially stored in the memory means by using the recorded RTC signal, and stored when the display button signal is set. The purpose of the present invention is to provide a method of automatically displaying the recording information of V-CAL, which improves the convenience of using the system since the recording information of the currently mounted video tape can be known by displaying the recording information of the video tape.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2 of the V-C apparatus to which the present invention is applied, the head drum 3 provided with a plurality of heads 2A and 2B for reproducing or recording the information signal contained in the video tape 1, and the head drum. The drum motor 4 for rotating the motor 3 at a set mode rotational speed, the drum motor driving unit 5 for driving the drum motor 4, and the tape 1 when the video tape 1 is loaded. Capstan motor (6) for rotating according to the set mode signal, Mode switch (7) for switching to the set mode signal is installed in the lower portion of the capstan motor (6),

The recording information recorded in the video tape 1 is displayed as an index screen for each item, and the recording information of the tape is stored in accordance with the storage control signal of the microcomputer 8 and the microcomputer 8 which generally control the functions of the system. It consists of the memory part 9.

Then, at one end of the microcomputer 8, the video signal processor 10 for processing video signals to be reproduced or recorded by the head 2A and the audio signals reproduced or recorded from the head 2A are voiced. The audio signal processing unit 11 for signal processing is connected, and the other end of the microcomputer 9 is connected with a key input unit 12 for inputting a user's function setting signal, and the other end of the microcomputer 8 has a character. An OS 13 that generates a signal is connected.

In addition, a display 14 is connected to the video signal processor 10, and a speaker 15 is connected to the audio signal processor 11.

Here, one side of the head drum 3 is provided with a control head 2B for reproducing or recording the control signal CTL, and the control head 2B also inputs the control signal to the microcomputer 8.

Next, the method of the present invention applied to the above apparatus will be described.

In the method of the present invention, as shown in FIG. 3, the microcomputer 8 proceeds from the initial step S1 to the tape mounting decision step S2 to determine whether the tape is mounted in the deck from the current user. As a result of the judgment during the tape mounting decision step S2, if the tape is not mounted on the deck, the process returns to the previous step S1 to repeat the loop. However, if the current tape is inserted into the deck as judged during the tape loading determination step (S2), the process proceeds to the tape recording information clearing step (S3), where all the recordings of the currently mounted tape stored in the memory means are recorded. The information is cleared and the process proceeds to the recording function setting judgment step (S4). As a result of the judgment during the recording function setting judgment step S4, if the recording function is not set, another set function is executed and the process proceeds to the end step. However, if it is determined during the recording function setting determination step (S4) that the recording function is set, the process proceeds to the tape recording start information storage step (S5) and stores the tape recording start information.

That is, when the tape 1 is inserted and the recording function is set, the microcomputer 8 clears all the recording information of the tape 1 stored in the memory unit 9, executes the recording function, and stores the start information. At this time, the microcomputer 8 inputs the rewind mode control signal to the mode switch 7. Then, by the rewind mode switching action of the mode switch 7, the capstan motor 6 drives the feed reel of the deck at the rewind mode (REW) speed. Accordingly, the tape 1 moves rapidly from the winding reel to the feeding reel so that the heads 2A and 2B are positioned at the very beginning of the tape. At this time, the RTC (REAL TIME COUNTER) is reset to zero. Then, the microcomputer 8 inputs the recording control signal to the drum motor driving unit 5 and the mode switch 7. Then, the drum motor driving unit 5 drives the drum motor 4 and accordingly the drum motor. The head drum 3 interlocked with (4) rotates. The head 2A provided in the head drum 3 writes information to be recorded on the tape 1, for example, an information signal input from a tuner (not shown). At this time, the control head 2B also records the control signal CTL on the control track corresponding to the first recording portion of the tape 1, for example, recording 30 pulses per second. In addition, simultaneously with the operation, the mode switch 7 also drives the capstan motor 6 according to the operation control signal of the microcomputer 8, and accordingly, the tape 1 moves through the head 2A, so that the recording function is executed. Will be. During the operation, the microcomputer 8 counts the number of pulses of the control signal corresponding to the first recording portion by RTC, and records the recording proxy point in the memory unit 9, where the recording channel and the recording speed SP, EP are recorded. ) Is also stored in the memory unit 9.

On the other hand, after the tape recording start information storage step (S5) proceeds to the recording function end determination step (S6) to determine whether the current recording function is terminated, and if the recording function is not terminated as a result of the previous step ( Returning to S5), the loop is repeated. However, as a result of the determination in step S6, if the current recording function is terminated, the process proceeds to the tape recording end information storage step S7 and stores the recording end point information counted by the RTC in the memory part. After the tape recording end point information storage step (S7), the process proceeds to the recording information display signal setting determination step (S8) to determine whether the recording information display signal is set, and if the recording information display signal is not set as a result of the determination, Proceed to end step. However, if the recording information display signal is set as a result of the determination during the recording information display signal setting determination step (S8), the process proceeds to the tape recording information display step (S9) to record the recording information about the tape currently stored in the memory unit. It is displayed on the display for a certain time.

That is, when the recording function is terminated, the microcomputer 8 stores the recording end time information in the memory unit by using the RTC. At this time, if the recording information display signal is set through the key input unit 12, the microcomputer 8 displays all the recording information of the tape stored in the memory unit 9 through the OS 13 as shown in FIG. The same screen is displayed on the display 14.

Thus, the user checks the recording information displayed on this display 14 to execute the function of the desired tape.

As described above, the present invention sequentially stores the recording information of the video tape in the memory means by using the recorded RTC signal when the video tape is recorded, and displays the recording information of the stored video tape when the display button signal is set. This allows you to know all the recorded information of the currently installed videotape, thus improving the convenience of using the system.However, it is possible to simply display a large number of information contained in the tape on the display without any complicated key manipulation. There is also an effect to increase.
