Abstract

PURPOSE:To easily confirm the tape position by integrating a semiconductor memory capable of data write/read in a space of a case with respect to a magnetic tape to extend the function of a conventional paper label. CONSTITUTION:The semiconductor memory 6 is integrated in the case space with respect to the magnetic tape 10, required information is stored in the memory and the information is utilized by a CPU 15 through an interface 14. For example, in using data such as a tape rotating pulse, a reel diameter and a tape thickness from a servo mechanism control circuit 12, the position of the tape 10 is calculated by the CPU 15. Further, the content of the tape 10 is stored in the memory 6 through A/D, D/A converter 17 and the interface 14 and the data is used for the user freely as retrieval information at the reproduction of the tape 10. Thus, it is not required to describe the information of the recorded content onto a paper label and the position of tape is retrieved easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cassette tape used for recording and reproducing signals such as video, audio, and numerical values.

[Conventional technology]

Figure 3 shows a plan view and a rear view of a conventional video cassette of the VH8 system. In the figure, 1 is the cassette tape case, 2 is the part where the top label is attached, and 3 is the part where the back bell is attached. , 4 is a tape take-up reel inside the case 1.

In the video cassette described above, an upper label and a back label (both not shown) made of paper are respectively pasted on the top label affixing part 2 and the back label affixing part 3. Information such as the video cassette manufacturer's name, the VHS mark, the product name, and the length of the video tape is typically printed on the label. Then, the user of the video cassette writes information about the recorded content in the margin of the label, such as the title, explanation of the recorded content, recording date, recording time mode, recording method, or the position on the magnetic tape at which recording started.

Here, the position on the magnetic tape is indicated by the number of revolutions of the tape take-up reel or a signal recorded on the tape indicating the recording start position.

[Problem that the invention seeks to solve]

Conventional video cassettes are constructed as described above, so the user has to fill in the information corresponding to the content recorded on the tape in the margins of the paper label. Misreading due to handwritten characters9, rewriting the label is time consuming, and complicated work is required, such as counting the number of reel revolutions and recording landmark signals to indicate the position on the magnetic tape. Ta.

This invention was made to solve the above-mentioned problems, and provides a cassette with an IC memory that does not require writing information about the recorded contents on a paper label and can easily indicate the position on the tape. Aim to get the tape.

[Means for solving problems]

The cassette tape according to the present invention incorporates a semiconductor memory capable of recording and reproducing various information in the space of a cassette case.

[For production]

In the cassette tape of the present invention, after information is recorded in a semiconductor memory by a cassette manufacturer, information corresponding to the recorded contents and information on the position on the tape are directly recorded by the user or a tape recording/reproducing device. Can be used during playback.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
Figure (a) shows a plan view of the VHS cassette case 1.
is the tape take-up reel inside the case. Φ) The figure shows the inside of a part of the lower right corner of the case 1, and 5 shows the space of a part of the corner. In this space 5, a board 8 on which a semiconductor memory 6 and its backup battery 7 shown in figure (d) are mounted is mounted. It is accommodated. (C) is a bottom view of a portion of the corner of the cassette case 1, and 9 is an electrode for writing to and reading from the semiconductor memory 6.

The video cassette constructed as described above is loaded into a magnetic tape recording/reproducing apparatus, and at this time, the bottom surface of the cassette shown in FIG. 1(C) is pressed against the reference surface of the recording/reproducing apparatus. Therefore, an electrode (not shown) opposite the α pole 9 of the cassette
By providing this in the reference plane of the recording and reproducing device, the semiconductor memory 6 of the cassette is always used when recording and reproducing signals on the tape.
In addition to being able to write and read signals to and from the semiconductor memory 6, the semiconductor memory 6 can also be used simply when loading a cassette.

FIG. 2 is a block diagram of a cassette according to the present invention. Conventionally, a magnetic tape 10 is used to record and reproduce a signal processing circuit 11 and a servo mechanism control circuit 1.
In this invention, a semiconductor memory 6 is added to the magnetic tape 10, and the magnetic tape length, thickness, reel diameter, manufacturer's name, 5A Data such as manufacturing lot and tape type are recorded as fixed information and used by the CPU 15 through the interface 14. For example, by combining the magnetic tape reel rotation knobs from the servo mechanism control circuit 12 with the data on the reel diameter and tape thickness, the position kcP of the magnetic tape 10 can be more accurately determined than before.
It can be calculated with U15. In addition, an explanation of the contents of the magnetic tape 10, the recording date and time, and recording conditions can be recorded in the semiconductor memory 6 by the keyboard 16, and the contents of the tape 10 itself can be
/b.

The progress can also be recorded in the semiconductor memory 6 by the converter 17 and the interface 14. The user can freely use these data as search information when playing back the magnetic tape.

In the embodiment, the semiconductor memory 6 is incorporated into a VHS cassette, but the semiconductor memory may also be incorporated into a space such as a β-type video cassette or a connosect cassette.

In addition, as shown in FIG. 1(a), it is also possible to attach a paper label to the case by providing a thin semiconductor memory or a pole 18 in the same shape as the paper label in the portion 2.

〔Effect of the invention〕

As explained above, according to the present invention, since the semiconductor memory capable of writing and reading data is incorporated into the case space of the tape, the functions of conventional paper labels can be expanded to a wider width. This has the advantage that all positions on the tape can be easily known.
