Abstract

PURPOSE:To recognize the content of a tape even on a different VTR by providing a magnetic seal on a cassette and providing a means for writing and reading its information. CONSTITUTION:Information recorded on a magnetic seal 1 is read by a reading head 5 at the time of inserting a cassette tape 2. At this time, a reading signal (b) is sent from a microprocessor 15 to a switch 13 and the head 5 and a reading section 14 are connected by the switch 13. The read signal is decoded by the reading section 14 and then, stored in a memory 16 via the processor 15. After that, it is displayed on a TV22. When it is newly recorded on the tape, a writing signal (a) is outputted by the processor 15 while a switch 11 is closed. Then, information about the contents previously and newly recorded on the tape is sent to a head 4 through a writing section 12 and written on the magnetic tape 1 again.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus capable of recording / reproducing the contents recorded in a cassette tape on the surface of a cassette.

[0002]

2. Description of the Related Art In recent years, people who own a VTR have a large number of cassette tapes. Therefore, proposals for organizing the recorded contents of them are being made. For example, if you attach a barcode indicating the cassette number to the label of the cassette tape and insert the cassette tape into the VTR, you can read the number and display the contents corresponding to the number registered in advance in the VTR on the TV screen. indicate.
When new recording is performed, the registered content in the VTR is updated.

Hereinafter, such a conventional proposal will be described. FIG. 4 shows a cassette tape, 2 is a cassette tape, 3 is a label, and 17 is a bar code. The contents of the cassette are written on the label, and the barcode is
A code corresponding to the number of the cassette tape is printed.

FIG. 5 is a schematic view showing a state in which a cassette tape is inserted into a VTR. When the cassette tape 2 is inserted into the VTR 10 in the direction of 6, it is loaded at the position of 7, and the tape 9 is wound around the cylinder 8 as shown in the figure. When the cassette is loaded, the bar code attached to the VTR is read by the reading head 18 to read the cassette number. That is, as shown in FIG. 6, the barcode 17 is read by the reading head 18, and the reading unit 19 is used.
Then, it is sent to the microprocessor 20. The contents of the cassette tape registered in advance are stored in the memory 21.
Read out and displayed on the TV screen 22. When newly recording, the microprocessor 20 is used and the memory 21 is used.
Rewrite the contents of.

[0005]

However, in such a conventional method, the bar code on the cassette merely indicates the cassette number, and the information in the cassette can be read only by the registered VTR. Can not. Of course, if this cassette is used in another VTR, the contents cannot be read.

The present invention solves this problem, and an object of the present invention is to provide a magnetic recording / reproducing apparatus capable of easily knowing the contents of a cassette tape.

[0007]

In order to achieve the above object, the present invention adopts a magnetic seal instead of a conventional bar code, and provides a VTR with a head for writing and reading on the magnetic seal. Have a configuration.

[0008]

With the above structure, information about the recorded contents of the cassette tape can be recorded and reproduced on the magnetic seal.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the magnetic seal 1 is attached to the upper part of the cassette tape 2. Figure 2 shows the VTR.
As shown in, for recording information on the magnetic seal 1,
Write head 4 and read head 5 for reading
To provide.

As shown in FIG. 3, the information recorded on the magnetic sticker 1 is read by the reading head 5 when the cassette tape 1 is inserted. At this time, the read signal b is sent from the microprocessor 15 to the switch 13, and the switch 13 connects the read head 5 and the read unit 14. The read signal is decoded by the reading unit 14, and then stored in the memory 16 via the microprocessor 15. Further, it is displayed on the TV screen 22.

When the tape is newly recorded, the write signal a is output by the microprocessor 15 and the switch 11 is closed. Then, the information about the content of the tape recorded up to that point and the information about the newly recorded content is sent to the writing head 4 through the writing unit 12 and rewritten on the magnetic sheet 1.

As described above, according to this embodiment, since the magnetic seal is provided on the cassette and the information writing / reading means is provided, the contents of the cassette can be easily known.

[0013]

As is apparent from the above embodiments, according to the present invention, since the contents of the tape are written on the cassette tape, the contents of the tape can be known even by different VTRs, and the memory 16 can be used. In addition, a magnetic recording / reproducing apparatus capable of constructing a cassette tape library can be provided by storing and storing the numbers and contents of the cassette tapes thus far.
