[Technical Field of the Invention] The present invention relates to a magnetic recording/reproduction device, and in particular, in a recording mode, control information such as a tape position regarding a program to be recorded is recorded at a predetermined magnetic tape position, and in the next recording or reproduction mode, control information such as a tape position regarding a program to be recorded is recorded. The present invention relates to a magnetic recording and reproducing device that can reproduce and monitor information, and that records and reproduces information based on this control information. [Technical background of the invention and its problems] Conventionally, magnetic recording and reproducing devices (hereinafter referred to as VTR)
When you record the desired program on tape with
Write the number on the tape counter installed on the VTR and the program name on the case that stores the tape. Furthermore, in order to record additional programs, the user visually observes the tape remaining on the supply reel through the transparent plastic case, checks the number on the tape counter, and performs the recording operation. When the numbers on the tape counter are different, or when you load a new cassette tape with a partially recorded program and want to record additionally, fast forward to the number on the tape counter and make sure it is not at a position that has already been recorded. You will need to take steps such as:
When playing, fast forward to get the desired program.
The beginning of the tape is found by rewinding or other playback operations. The disadvantage is that all operations related to recording and reproduction must be performed at the discretion of the user. For the purpose of the following explanation, we will refer to the magnetic tape (tape), the beginning of the supply reel (start and end), the distance from the beginning of the tape (position...meaning the so-called absolute address and absolute distance), and the program record. (recording), the first position of recording (starting position), the last position of recording (stop position), and the encoding of various numerical values and character characters necessary for recording and playback procedures (data or information code) , visualized data (video signal), data and video signal (control information), control information recording area (information area) provided at the beginning of the tape, etc. are shown in parentheses. [Object of the Invention] The present invention has been made in view of the above-mentioned points, and the present invention records data such as the position of the recorded program and the remaining time that can be recorded at a predetermined position on the tape, and records the data at the time of playback. To provide a magnetic recording/reproducing device configured to display selected data on a television receiver, automatically fast-forward a tape to a selected program, and automatically reproduce the selected program. [Summary of the Invention] The present invention is provided with tape position detection means for detecting the magnetic tape running position. When a recording operation is performed, the data of the program to be recorded and the data of the position where the program was recorded are converted into video signals. This video signal and data related to the video signal are recorded at the beginning of the magnetic tape, and by monitoring the reproduced video signal, it is designed to serve as a reference for recording and reproducing operations. When a recording/reproducing operation is performed, recording/reproducing control is automatically performed according to the data stored in the storage device. [Embodiment of the Invention] Hereinafter, an embodiment of the magnetic recording/reproducing apparatus according to the present invention will be described in detail with reference to FIG. In FIG. 1, 1 is a tape position detection circuit. The tape position detection circuit 1 detects the output from the supply reel stand 3 and take-up reel stand 4 of the cassette tape 2 via rotation detectors 3a, 4a and rotation speed calculation circuits 3b, 4b. The length of the tape wound on each reel is calculated from the rotation speed of the take-side reel stand 4 and output. Tape position detection circuit 1 sends the obtained position data to system control circuit 5 and information setting circuit 6. The information setting circuit 6 transfers data related to the program to be recorded according to the operation of the control buttons B1 and B0 to the switch 7.
RAM8 via the normally closed contact 7b and switching contact 7c.
to be memorized. When recording starts, the position data obtained by the tape position detection circuit 1 is used as the start position data.
Store it in RAM8. At the end of recording, end position data and data relating to the remaining amount of tape are stored in the RAM 8. The recording video signal S1 is transmitted from the terminal 13 to the video input circuit 14, the normally closed contact 15b of the switch 15, the switching contact 15c, the recording signal processing circuit 16, and the mode switch 1.
The data is recorded on the magnetic tape 24 via the normally closed contact 17b of No. 7, the switching contact 17c, and the video head 18. The video signal conversion circuit 19 receives program data related to recording stored in the RAM 8 through the gate 12 when recording is completed, converts this data into a video signal, and switches the switch 15 from closed to normally open. The signal is sent to the video head 18 via the contact 15a and the switching contact 15c. The system control circuit 5 learns from the data in the RAM 8 that recording of the program has ended, and controls the supply side reel stand 3 using control signals M 1 to M o to rewind the magnetic tape 24 to the beginning. Data converted into a video signal obtained by the video signal conversion circuit 19 is recorded in the information area at the beginning of the magnetic tape 24. The recorded data, ie control information, is shown in the table. When a recording/reproducing operation is performed, the magnetic tape 18
The control information shown in the table recorded at the beginning of the volume is input to the reproduction signal processing circuit 20 via the video head 18 and the closed switching contact 17c and normally open contact 17a of the mode switching device 17.
