Abstract

PURPOSE:To enable prompt and accurate retrieval of program contents recorded on a tape cassette by recording program content information recorded on the cassette tape on a shifting cassette magnetic face and by reproducing this in the same manner. CONSTITUTION:After a television program is recorded through a television tuner on a cassette tape of a tape cassette 1, the cassette 1 is shifted for ejection by rollers 4 and 5. Then on a magnetic filter 2 of the cassette 1, the information such as channels etc., is recorded, which corresponds to the television program recorded by the television tuner, etc., through a magnetic head 3. At the time of inserting this cassette 1, the contents of the filter 2 are reproduced; the contents of the cassette tape are retrieved and the television tuner, etc., are actuated in response to the corresponding channel, thereby enabling prompt and accurate retrieval of the recorded program contents.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a program content recording and reproducing apparatus that can accurately and quickly search program content recorded on a tape of a tape cassette.

[Prior Art] In other words, in a tape cassette of a video tape recorder, the program contents recorded on the tape cannot be visually determined. Therefore, in order to understand what kind of program was recorded on the tape, the tape was played back for a considerable period of time to determine what kind of program was recorded. However, with this method of discrimination, if the tape force setting 1- increases,
When a plurality of programs are recorded on one tape cassette, it takes a long time to search for the desired #7 phase, which is inconvenient.

Therefore, with conventional tape cassettes, the method of applying memo paper, etc. to the surface of the tape cassette, or preparing a separate memo paper with the number of the tape cassette written on it, and manually writing the recorded program on the memo paper, etc. has been adopted. -(Yes. However, such conventional methods have the disadvantage that writing on memo paper and storing memo paper are time-consuming and troublesome.

[Summary of the Invention] The present invention has been made against the above-mentioned background, and an object of the present invention is to provide a device that can accurately and quickly search program contents recorded on a tape cassette.

Simply put, this invention uses a tape cassette in which a magnetic film for recording information is provided on a predetermined surface, and when a program is recorded on the tape, the IT set content information is automatically recorded on the magnetic film. This is a device that can quickly grasp the program contents recorded on a tape cassette by recording the information recorded on the magnetic film and reproducing the information recorded on the magnetic film during playback.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

[Embodiment of the Invention] FIG. 1 is a perspective view showing a tape cassette of a video tape recorder used in an embodiment of the invention. In the figure, inside the Arp cassette 1, y--1, which does not appear in the figure, is stored.

For example, a television program is recorded on this magnetic data 1. A magnetic film 2 is provided on one side of the tape cassette 1. Information related to the contents of the it set is recorded on this magnetic film as described above.

FIG. 2 is a diagram schematically showing the relationship among the tape cassette 1, the rollers 4 and 5 that move the tape cassette 1, and the magnetic head 3 that comes into contact with the magnetic film 2. The tape cassette 1 is housed in a cassette holder (not shown) of a video tape recorder, and when installed, the tape cassette 1 is placed between rollers 4115 and 5.
is moved in the direction of the arrow. After a television program or the like is recorded on the tape, it is moved by rollers 4 and 5 in the direction shown by arrow a, thereby being ejected from the cassette holder and taken out from the video tape recorder.

FIG. 3 is a block diagram of a recording system circuit according to an embodiment of the present invention. Further, FIG. 4 is a block diagram of a reproduction system circuit according to an embodiment of the present invention.

First, the configuration and operation of the recording system circuit of this embodiment will be explained with reference to FIG. 2J3 and FIG. 3. In FIG. 3, it shows, for example, which channel of television broadcasting is being received, which is output from the television tuner 6.
P. Rennel program information passes through the gate 10 and is stored in the memory 7. After the recording of the program on the tape stored in the tape cassette 1-1 is completed, the tape cassette 1 is removed from the video tape recorder by pressing a predetermined button (not shown). is roller 4 d
3 and 5, the tape is moved as indicated by the arrow a in FIG. 2 and ejected from the video tape recorder. At this point, in response to the above-mentioned predetermined button being pressed,
Cassette switch 9 closes and gives a command to memory 7.

The contents stored in the memory 7 are then modulated by a modulation circuit 8 and applied to the magnetic head 3. At this time,
Since the magnetic head 3 is in contact with the magnetic film 2 of the tape cassette 1 that is being moved for ejection as described above, the memory contents are recorded on the magnetic film 2 by the magnetic head 3. In this way, for example, how many channels of television broadcasting have been recorded can be determined by the magnetic film 2 provided on the tape cassette 1.
automatically recorded. When programs of a plurality of channels are successively recorded on one tape cassette, since the contents are stored in the memory 7, the program information of each channel is recorded on the magnetic film 2.

In addition, in FIG. 31, the system control circuit 1
1 detects that the video tape recorder is in the recording state and closes the gate 10.

Next, with reference to FIGS. 2 and 4, the configuration and operation of a reproducing circuit according to an embodiment of the present invention will be described. When installing tape cassette 1 into a video tape recorder and trying to play back the contents of the tape, tape cassette 1
is moved in the direction of the arrow in FIG. At this time, the signal recorded on the magnetic film 2 is extracted by the magnetic head 3. In FIG. 4, the signal extracted by the magnetic head 3 is demodulated by the v111 circuit 12 and stored in the video RAM 1.
3 in the form of a video signal. And video RA
The contents of M13 are mixed with the signal of the video signal circuit 15 in the mixer 14 and displayed on the television receiver 16.

In this way, in this embodiment, the data regarding the program content recorded on the tape cassette 1 is stored on the tape cassette 1.
Since the content of the program recorded on the tape cassette 1 is displayed on the television receiver 116 at the same time as the tape cassette 1 is attached, the content of the program recorded on the tape cassette 1 can be known reliably and quickly.

In the above explanation, the content recorded on the magnetic tape 12 of the tape cassette 1 is, for example, the broadcast channel number, which channel of the television broadcast.
The recorded content is not limited to this, and various information such as the count value of a tape counter indicating the winding condition of the tape, date, day of the week, time, etc. may be recorded.

Further, in the tape cassette 1 of this embodiment, the magnetic film 2
Although it is provided on one side of the tape cassette 1, it is not limited thereto, and may be provided on any other surface as long as it is parallel to the moving direction when the tape cassette 1 is mounted and ejected.

In the above description, the case where the present invention is applied to a video tape recorder is expressed, but the present invention can also be applied to, for example, an audio tape recorder.

[Effects of the Invention] As described above, according to the present invention, information related to the program content recorded on the tape of the tape cassette can be magnetically recorded and reproduced on a predetermined surface of the tape cassette. Therefore, data related to the recorded program content can be retrieved, and the program content can be searched accurately and quickly.
