摘要： A multichannel magnetic head includes a plurality of sets of magnetic core half bodies, each of the sets having two of the half bodies facing each other, and a plurality of magnetic gap portions, each of the gap portions located where two magnetic core half bodies face each other. The plurality of magnetic gap portions, when a magnetic medium is inserted therein, transferring record data between the magnetic medium and the magnetic head, and the gap distances of the magnetic gap portions being differentially preset to accommodate a physically warped magnetic medium. A magnetic card reader including a multichannel magnetic head has a plurality of magnetic gap portions, and the multichannel magnetic head is capable of recording data onto a magnetic medium in contact therewith. The multichannel magnetic head has gap distances that can be modified based on a possibility of spacings between the multichannel magnetic head and the magnetic medium so that a warped card can be accommodated.

摘要： A method for judging coercive force of a magnetic card to judge coercive force of a magnetic card to be used. According to the method for judging coercive force of a magnetic card for reproducing or recording magnetic information formed on a low coercive force card or a high coercive force card inserted from a card slot by a magnetic head, after erasing data of an inserted card by an electric current capable of erasing data of only a low coercive force card (step S32), the data of the card is reproduced (step S33), the inserted card is judged as the low coercive force card (step S36) if the data has been destroyed (No at the step S34). Destruction of the data is judged based on the number of times of flux reversal of the reproduced data or by a fact that specific data (STX code) which should be recorded on a predetermined card is not recognized.

摘要： A magnetic card reader comprises a card insertion slot, a magnetic head for regenerating or recording magnetic information formed on a card to be inserted in the cart insertion slot and a determining device to determine coercive force of a data track for recording magnetic information of the card. A method for determining the coercive force of a magnetic card in a magnetic card reader in which magnetic information formed on a card to be inserted from a card insertion slot is regenerated or recorded by a magnetic head comprises the steps of providing a detecting portion which detects a change in static characteristics of the magnetic head and determining the coercive force of a data track by comparing output from the detecting portion, which detects a change in static characteristics of the magnetic head while being positioned across from the card, with a reference signal.

摘要： A magnetic head having a head unit for contacting a magnetic medium comprises at least a pair of magnetic cores which are arranged in the head unit which face each other on sides of a magnetic gap for recording and/or reproducing signals. A spacer is included for maintaining a space between one of the magnetic cores and another member, which may be the other magnetic core or a shield member. The spacer includes a usable life detection device for providing an indication of wear on the head unit which is interrupted when the head unit is worn down to predetermined depth. A device for electrically sensing an interruption of the indication is provided so that a usable lifetime of the head unit can be determined.
