Description

  The present invention relates to a magnetic recording card encoding apparatus for writing recording information on a magnetic recording card having a magnetic recording unit.

  In recent years, membership cards, cash cards, credit cards, prepaid cards, boarding commuter passes, electronic money, and other cards are generally used. Among them, magnetic recording cards having a magnetic recording portion on the card surface are convenient and durable. The magnetic recording card is generally used in various fields and is widely spread. Magnetic recording cards are generally a magnetic stripe card having a strip-like magnetic recording portion on the card surface and a magnetic card having a magnetic recording portion on the entire card surface. Can be classified.

  A magnetic stripe card is generally made by thermocompression bonding a magnetic stripe having a magnetic recording portion on the surface of a plastic card made of a resin such as PVC (hard vinyl chloride) or PET-G (amorphous polyethylene terephthalate copolymer). . According to the JIS standard, the thickness of the magnetic stripe card is 680 μm to 840 μm, and it has the mechanical strength and durability assumed to be necessary for daily card handling. It is often used for cards that are used repeatedly over a long period of time, such as credit cards, cash cards, and membership cards that are recorded in a magnetic recording unit.

  A magnetic card is generally made by applying a magnetic recording portion to a card base made of a resin such as paper or PET (polyethylene terephthalate), or by thermocompression bonding. According to the JIS standard, the thickness of the magnetic card is 180 μm to 290 μm, and it is often used for prepaid cards etc. for disposable applications that do not require mechanical strength and durability such as magnetic stripe cards. Is recorded in the magnetic recording section.

  Personal authentication to the magnetic recording part of the magnetic recording card, writing of record information such as a cash voucher is recorded as a magnetic signal via the magnetic head, and the magnetic signal is read from the magnetic recording part via the magnetic head, and personal authentication and cash voucher are recorded. Etc. can be obtained. In order to perform writing and reading of magnetic signals to and from such a magnetic recording unit with good reproducibility, the magnetic recording unit must be free from foreign matter or damage due to trauma. Further, it is known that the magnetic recording section is generally standardized and must have magnetic characteristics such as standardized reproduction output voltage and jitter.

  In general, in a magnetic recording card, a magnetic signal composed of fixed data is written once to a magnetic recording unit via a write-only magnetic head during the card manufacturing process, and then magnetically recorded from the magnetic recording unit via a read-only magnetic head. Read the signal once, measure the playback output voltage and jitter once from the read magnetic signal, judge the quality, erase the magnetic signal of the magnetic recording part with the dedicated magnetic head only for the good product, and obtain the magnetic recording card Such a magnetic recording card manufacturing method, inspection method, and inspection apparatus are disclosed in, for example, Patent Document 1.

  Writing personal information to a magnetic recording part of a magnetic recording card and recording information such as a cash voucher is generally called encoding, and personal authentication to the magnetic recording part and recording of a cash voucher or the like through a single writing / reading magnetic head It is known that information is written, and then recorded information such as personal authentication and cash vouchers is read from the magnetic recording unit, and the written record information is compared with the read record information. Such an encoding method and an encoding apparatus for a magnetic recording card are disclosed in, for example, Patent Document 2.

  Conventionally, a magnetic recording card is determined to be a non-defective product if the recorded information read at the time of encoding matches the written recorded information. In general, a magnetic recording unit that has been confirmed to have a magnetic signal with a certain magnetic property quality, when the magnetic signal is erased and then written again, a magnetic signal that is substantially equivalent to the magnetic property quality before erasure is obtained. It is known to be obtained. In addition, the prior art magnetic property measurement and evaluation apparatus performs measurement by reciprocating several times with a single built-in magnetic recording card reader / writer, and it is difficult to process a large amount due to the long processing time. There is no measurement and evaluation of the magnetic characteristics of the magnetic signal written during encoding.

  By the way, the writing of the magnetic signal to the magnetic recording portion of the magnetic recording card is performed by bringing the magnetic head into contact with the magnetic recording portion, but at the time of writing, there is a foreign object between the magnetic head and the magnetic recording portion, An air gap is generated between the magnetic head and the magnetic recording unit, writing to the magnetic recording unit becomes insufficient, the magnetic signal of the magnetic recording unit is weak, and generally, a standardized and standardized reproduction output voltage and There are cases where magnetic characteristics such as jitter are not satisfied, a magnetic signal having no omission is not obtained from the magnetic recording section via a magnetic card reader, and recording information cannot be obtained correctly from the magnetic recording card.

  A general encoding apparatus performs writing and reading with one magnetic head, and since the writing position and reading position of the magnetic head are almost the same, the magnetic signal written to the magnetic recording portion of the magnetic recording card is not lost. Can be read, but when a magnetic recording card is used in the market, it is read by multiple magnetic card readers / writers, and the positional relationship between the magnetic head and the magnetic recording unit and the contact state between the magnetic head and the magnetic recording unit are different. In general, the loss of the magnetic signal written in the magnetic recording part is unavoidable. Therefore, in a general magnetic card reader / writer, in order to prevent a non-defective card from being read due to the loss of the magnetic signal, the read output is amplified or converted from a magnetic signal to an electrical signal. The threshold may be set low.

  Therefore, when there is a foreign object between the magnetic head and the magnetic recording unit at the time of writing and the writing to the magnetic recording unit is insufficient, the reproduction output voltage and jitter of the magnetic signal read from the magnetic recording unit The magnetic characteristics are standardized and near the lower limit value of the standard that is standardized, and in other magnetic card reader / writers, reading of recorded information from the magnetic recording unit becomes unstable. In other words, among encoded magnetic recording cards supplied to the market as non-defective products by the encoding device, there is a possibility that a magnetic recording card that cannot read recording information such as personal authentication and cash voucher may occur from the magnetic recording unit. there were.
