Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic card cartridge that accommodates a plurality of magnetic cards used as recording media in a magnetic recording/reproducing device in a superimposed manner and has a limited recording capacity.

Conventionally, as is well known, the recording capacity of recording media such as magnetic tapes and magnetic cards used in magnetic recording and reproducing devices is proportional to the area of the recording medium.
Although the recording capacity can be increased by increasing the length of the tape, it is relatively small because it is wound on a reel, making it convenient for recording music over a long period of time, recording the contents of a meeting, etc. .

On the other hand, since magnetic cards have a dog-like shape in proportion to their recording capacity, they are generally not used as a dog-shaped card.

By the way, in magnetic recording and reproducing devices used in educational machines, office machines, answering machines, etc., information signals with a relatively small amount of information are often recorded sequentially, and the information signals are selectively reproduced. Therefore, it is desirable to have a recording medium that not only has a large recording capacity but also allows easy selection of recorded information signals.

Although magnetic tape has a high recording capacity, it is not suitable for selecting recorded information signals as the above-mentioned recording medium.

In other words, when attempting to reproduce an information signal recorded near the end of a magnetic tape, the magnetic tape must be rewound and then reproduced, which takes time, and it is difficult to locate the recording location of the information signal to be reproduced. It cannot be easily detected visually, and must be detected using a display such as a tape counter.

Further, since the magnetic card cannot have a limited storage capacity due to the problem of its shape as described above, simply using a single magnetic card is not suitable as the above-mentioned recording medium.

Therefore, in order to solve the above-mentioned drawbacks, increase the recording capacity, and selectively record or reproduce information signals, the present invention stores a plurality of magnetic cards in a superimposed manner. A magnetic card cartridge equipped with a magnetic card search means is provided.
