As shown in the figure, the first determination step is a step of checking whether a learning-only recording key is input (S11) and a step of checking a tape position (S12).

The first processing step is a step performed when the first part of the tape in the first determination step, the step of rewinding until the start sensor is checked to return to the front of the tape (S13-S15) and a predetermined time (As a time that can be set arbitrarily, in the present invention, the case where it is set to 10 seconds will be described as an example.) The fast forwarding operation is performed to leave the first part of the tape blank by a predetermined length (S16-S18).

Also, the second processing step is performed when the first determination step is not the first part of the tape or after the first processing step. The second processing step detects and converts the current date and time data indicated by the VFD into characters. After that, the method stores the memory in the memory (S19) and proceeds with recording (S20).

The second determination step includes determining whether an end sensor is checked during recording in the second processing step (S21), and checking whether a recording stop key is input (S22).

The third processing step is a step performed when it is checked that the recording stop key is input in the second determination step. In step S23, the recording operation is terminated immediately after determining that the amount of tape that can be recorded remains. .

The fourth processing step is a step performed when the end sensor is checked in the second determination step, determining that the end of the tape has been recorded and stopping the recording operation (S24), and again until the start sensor is checked. Returning to the beginning of the tape by rewinding (S25-S27); and if the front of the tape is checked, sequentially writing the character information stored on the tape (S28-S29); After the contents are deleted, the process ends (S30).

Referring to the program information recording process recorded on the tape in the VCR according to the present invention configured as described above are as follows.

First, in the present invention, if the recording key is set by the user in the key input unit 7A and the like, and the learning-only recording key is input (Y branch in S11), the system controller 10A first starts the deck unit 5. A first determination step is performed to check whether the tape is to be emptied by a certain length by checking the position of the tape (S12).

Next, if it is determined in the first determination step that the first part of the tape is present, the system controller 10A performs a rewind operation until the start sensor is checked (S14), and immediately after the start sensor is checked (Y branch of S14). After the rewinding operation is stopped (S15), the first processing step of checking the time again (S17) and proceeding with the fast-forwarding operation for 10 seconds (S16) and then stopping (S18) to leave the first part of the tape empty by a certain length. Is carried out.

On the other hand, if the first determination step is not the first part of the tape (N branch of S12) or after performing the first processing step S18, the system controller 10A controls the VFD data detection unit 11 to the VFD window. After the current date and time data being displayed is detected and converted into characters through the character conversion unit 12, the data is automatically stored in the data memory unit 13 (S19), and then recording is performed (S20). 2 Perform the processing steps.

At this time, while performing recording in the second processing step, a second determination step of checking whether the end sensor is checked from the deck unit 5 (S21) or whether the recording stop key is input from the key input unit 7A (S22) is performed. do.

If it is checked in the second determination step that the recording stop key is input (Y branch of S22), it is determined that the amount of tape that can still be recorded is left, and a third processing step of immediately stopping the recording operation (S23) and terminating is performed. If the end sensor is checked in the second determination step (Y branch of S21), it is determined that the tape is recorded to the end of the tape, and the recording operation is stopped (S24), and then rewinding until the start sensor is checked (S26). Proceed (S25) to return to the beginning of the tape, and then control the data memory unit 13 to write the character information sequentially stored in the first part of the tape emptied (S28), and when the recording is completed (S29 At the same time as the recording stop, the fourth processing step of deleting the memory contents of the data memory section 13 (S30) and ending the procedure is performed. It will be automatically recorded in front of the tape.

Therefore, in the present invention, when a consumer wants to record a learning program on one tape from the beginning to the end, when the consumer inputs a learning-only recording key, the system controller receives the learning-only recording key and fast forwards the first portion of the tape by about 10 seconds. After that, if the consumer records again with the learning-only recording key, afterwards, the system detects and saves the data on the recording date and time and proceeds to record immediately. When it is detected, it returns to the front of the tape, which is emptied in advance, so that data about the recording date and time stored in the data memory unit can be recorded in the interval of about 10 seconds in front of the tape.

Although not shown in the present invention, when the consumer completes the learning-only tape and plays it again, the system controller detects the displayed character information on the OSD and waits for data input to play the part desired by the consumer in the stop state. When the consumer inputs the desired section, the system controller moves to the section and allows playback.

The present invention as described above is to record the OSD character information about the date or time when the learning program is recorded by recording the learning program that is broadcast periodically or every day on a single video tape using the learning-only recording key. Whenever it is judged that recording is completed on the whole tape afterwards, it automatically records OSD text information about the program for learning at the beginning of the tape so that the recorded contents of the tape can be notified at the beginning of playback so that the tape can be recorded from the beginning to the end. There is a useful feature that the user can easily recognize the tape recording without playing.
