Abstract

PURPOSE:To take out the information desired to be known only by inserting a tape cassette and display on a television screen or the like by recording and reproducing the information relating to the information recorded in a magnetic tape in the tape cassette on a magnetic recording medium provided on the surface of the tape cassette. CONSTITUTION:On an upper surface of a tape cassette 11, a magnetic recording medium layer 12 is disposed. At first, the tape cassette is inserted into an inserting section of the tape cassette in a direction shown by an arrow A. At this time, a magnetic head 13 attached to an upper surface of the tape cassette inserting section of a main body of a magnetic recording reproducer 15 contacts the recording medium layer 12 and is inserted and the tape cassette 11 is lowered toward the magnetic recording medium 12. By the movement of the tape cassette, a signal can be recorded or reproduced on the magnetic recording medium 12 on the tape cassette 11 by the magnetic head 13.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a magnetic recording/reproducing device that records information corresponding to the information recorded on the cassette tape on the surface of the tape cassette. The present invention relates to a magnetic recording/reproducing device that can display the recorded contents on a television screen or the like by simply inserting the tape cassette into the magnetic recording/reproducing device.

2. Description of the Related Art In recent years, household magnetic recording and reproducing apparatuses have become more popular, and the number of tape cassettes per magnetic recording and reproducing apparatus has also increased.

When a user wants to check the contents recorded on a tape cassette, he or she writes the contents on a piece of paper pasted on the tape cassette, or checks the contents by playing the tape.

Problems to be Solved by the Invention However, with the method described above, each time a new recording is made on the tape cassette, it is necessary to change the display paper and rewrite the data, or to replay it. There is a problem in that it takes a considerable amount of time to check the entire beginning and end of the tape cassette.

In view of the above-mentioned problems, the present invention provides a magnetic recording and reproducing device that can display recorded contents on a television screen simply by inserting a tape cassette into the magnetic recording and reproducing device.

Means for Solving the Problems In order to solve the above problems, the magnetic recording and reproducing apparatus of the present invention uses a magnetic recording medium layer provided on the surface of a tape cassette as a recording medium, and a magnetic head capable of recording and reproducing information. The magnetic head is provided in a tape cassette insertion section of the main body of the recording/playback device, and is linked to a tape cassette attachment/detachment device to reproduce and record information signals related to information recorded on the magnetic tape in the tape cassette onto the recording medium by the magnetic head. The reproduction signal is then displayed on a display means such as a television receiver.

Function: With the above-described configuration, the present invention enables the contents recorded on the tape cassette to be displayed on a television screen or the like by simply inserting the tape cassette into the main body of the magnetic recording/reproducing device.
It is something that the user can know.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of a video tape cassette used in the present invention, in which a magnetic recording medium layer 12 is provided on the upper surface of a tape cassette 11.

FIG. 2 is a schematic side view showing the process of inserting or removing the tape cassette 11 into the main body of the magnetic recording/reproducing apparatus of the present invention.

When inserting a tape cassette, the tape cassette 11 is first inserted into the tape cassette insertion portion in the direction of the arrow as shown in A. At this time, the magnetic head 13 attached to the top surface of the tape cassette insertion portion of the magnetic recording/reproducing device main body 16
The tape cassette 11 is inserted to the predetermined position shown in the fourth step while the tape cassette 11 is in contact with the recording medium layer 12. Next, as shown in Figure C, the tape cassette 11 is lowered toward the reel stand 14. Also, when taking out the tape cassette, it comes out by going through the directions shown in Figures B and B in reverse. The specific construction of this tape cassette attachment/detachment mechanism is a conventionally known construction.

FIG. 3 shows a block diagram of one embodiment of the invention.

The movement of the tape cassette allows the magnetic head 13 to reproduce or record signals on the magnetic recording medium 12 on the tape cassette 11. Signal processing by the magnetic head is shown in FIG. first,
When recording on the magnetic recording medium 12, information corresponding to the information recorded on the tape in the recording cassette is inputted using a signal input device 51 such as a keyboard. For example, the title of the recorded content, the recorded position, order, etc. are input. Next, the signal input by the signal input device 51 is converted into a signal that can be recorded on a magnetic tape by the recording signal converting means 52, and the recording current set by the recording timing setting means 68 is adjusted in conjunction with the ejecting operation of the tape cassette 11. Recording is performed on a magnetic recording medium by a magnetic head through a recording amplifier 53 at the timing of the flow.

Next, during playback, the magnetic head 13 extracts a signal from the magnetic tape 12 in conjunction with the ejecting operation of the tape cassette, the amplifier 66 amplifies the signal, and the video signal converter 66 converts the playback signal into a video signal. , is outputted by the output amplifier 57. That is, in recent VTRs, when a tape cassette is inserted into the tape cassette insertion slot, the insertion is detected by a switch or the like, and the insertion is detected by a switch or the like.

Since the operation (c) is automatic, playback can be performed in conjunction with the tape cassette insertion operation.

As described above, according to this embodiment, information related to the information recorded on the magnetic tape in the tape cassette can be recorded and reproduced on the magnetic recording medium layer provided on the surface of the tape cassette. The recorded information can be displayed on a TV screen, etc. by simply inserting it into the .

Effects of the Invention As described above, the present invention allows information related to the information recorded on the magnetic tape in the tape cassette to be recorded and reproduced on the magnetic recording medium provided on the surface of the tape cassette. Just by inserting it into the main body of the magnetic recording/reproducing device, you can retrieve the information you want to know and display it on a TV screen, etc.
