Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a recording medium that is capable of reading ticket types and the like and magnetically recording on a magnetic stripe during transportation.

BACKGROUND ART Conventionally, as information recording media, for example, bank cards or expressway passes having striped magnetic recording media have been developed and put into practical use. However, the magnetic stripe carried on such bank cards, expressway passes, etc. is only intended to record magnetic information, and other information (for example, the type of card or ticket) is not stored on the stripe. There was an inconvenience that cannot be recorded.

The present invention was made in view of the above circumstances, and its purpose is to provide a recording medium that can increase the amount of information by adding barcode information indicating the type of card, ticket, etc. to the magnetic stripe. That is.

The present invention will be explained below based on an embodiment shown in FIGS. 1 to 5. FIG. 1 shows a card 1 having a magnetic stripe portion, and the magnetic stripe portion 2 is constructed by printing a magnetic stripe 2A for recording magnetic information and a barcode 2B representing, for example, the type of card.

FIG. 2 shows the format of the magnetic stripe section. The barcode 2B is printed using the same material as the magnetic stripe section 2A, and the printed magnetic stripe section 2 and the paper surface of the card 1 are printed at an optical reflection level. It is meant to be read. In other words, a barcode consists of a 4-bit binary code, and for example, to represent the type of card 1, it is given binary weights of 1, 2, 4, and 8 from the tip of the card, and contains 16 types of information from 0 to 15. It is beginning to be expressed.

Furthermore, Fig. 3 schematically shows the magnetic information reading/writing mechanism, in which 3 is a transparent detector that detects the edge of the card 1 transferred in the direction of the arrow x, and 4 is a transmissive detector. A barcode reader 5 is used to read a barcode (not shown) recorded on the card 1, and a magnetic head 5 is provided after the barcode reader 4 to read and write magnetic information.

4a to 4g show timing charts in FIG. 3, in which a shows the timing pulse when the tip of the card 1 is detected by the detector 3, and b shows the timing pulse detected by the barcode reader 4 in FIG. Timing chart for reading barcode 5 during formatting, c is a timing chart for emitting 4 timing pulses to read the code from the tip of card 1, d to g are timing charts for each bit of each code by the timing pulses for c. This is a timing chart captured in parallel at points.

Furthermore, FIG. 5 shows a block diagram, in which 6 is a detection amplifier of the barcode reader 4, 7 is a timing generation circuit that generates four clocks from the tip detector 3, and 8 is a clock that is continuously transmitted. a data processing circuit that converts the received data into parallel data using the clock generated by the timing generation circuit 7;
9 is an interface circuit with the computer.

Next, the operation of the present invention based on the above configuration will be explained.

In FIG. 3, when the card 1 shown in FIG. 1 is being transferred in the direction of the arrow Barcode 2B is read by reader 4. Here, the data processing circuit 8 processes the continuously sent barcodes 2B at points as shown in FIG. 3 d to g, so that the type of the card 1 can be determined during transportation. .

In this way, the card 1 on which the barcode 2B has been read is further transported, and the magnetic head 5 arranged at the rear stage reads and writes the magnetic information recorded in the magnetic stripe 2A. Therefore, the magnetic head 5 can reliably read and write magnetic information in the magnetic stripe 2A depending on the type of card 1.

Although the stripe information of the barcode shown in one embodiment of the present invention has been described as a 4-bit binary code, it is not limited to this, and any other barcode information may be used.

As explained above, in a magnetic recording medium having a magnetic stripe, the present invention prints the magnetic stripe surface and the barcode information surface on the same line without separately printing barcode information indicating the type of the magnetic recording medium. Moreover, since the magnetic surface is used as a barcode, the price is lower and the amount of information can be increased. In addition, since it is possible to optically read barcode information and read and write magnetic information in one scan, it is easy to operate and has excellent effects such as being able to quickly process magnetic recording media. It is.
