  • Patent number: 9030778
    Abstract: A magnetic head includes a base, at least one magnetic transducer, at least one protection sheet, and a control circuit board. The magnetic transducer is set on an external surface of the base. The protection sheet is coupled to the external surface of the base and covers the magnetic transducer. The protection sheet covering the magnetic transducer prevents the magnetic transducer from direct exposure. The control circuit board is coupled to a bottom of the base and electrically connected to the magnetic transducer. The control circuit board may be electrically connected with a predetermined control device so that the control circuit board receives a read signal transmitted from the magnetic transducer and transmits the read signal to the predetermined control device. As such, using the magnetic transducer to read data may simplify the conventional magnetic head in respect of complicated components, size, manufacturing time, labor, and cost.

  • Patent number: 7044394
    Abstract: A payment card comprises a plastic card with a magnetic stripe for user account data. Internal to the plastic card, and behind the magnetic stripe, a number of fixed-position magnetic write heads allow the user account data to be automatically modified. For example, a data field that counts the number of times the card has been scanned is incremented. A payment processing center keeps track of this usage-counter data field, and will not authorize transaction requests that come out of sequence. For example, as can occur from a magnetic clone of a card that has been skimmed and tried later. A card-swipe detector embedded in the plastic card detects each use in a scanner, and it signals an internal microcomputer which changes data bits sent to the write heads. Once scanned, the payment card can also disable any reading of the user account data for a short fixed period of time.

  • Patent number: 6678103
    Abstract: Methods and apparatus for increasing the density of data storage on a magnetic medium by using variations in positioning of magnetic transitions to encode bits. Conventionally encoded bits are written to the medium as sequences of magnetic transitions according to an encoding standard. Additional bits are encoded on the medium as deviations from a nominal position of magnetic transitions separating conventionally encoded bits. The deviation from the nominal position is within an allowable range of tolerance for the standard followed in encoding the conventionally encoded bits. In order to prevent accumulation of error, additional bits are only encoded in transitions separating a pair of conventionally encoded bits. The first and last transitions of the pair do not have additional bits encoded as deviations of transition locations. This technique allows the encoding of one additional bit for every two conventionally encoded bits.

    Abstract: A technique for detecting a magnetic recording medium such as a strip on a magnetic card so as to distinguish between a case where a magnetic strip has high coercivity and one where it has low coercivity. A magnetic head detects the existence and appropriate positioning of a magnetic strip which is then fed to a permeability sensor that provides an output signal that is a function of the permeability magnetic strip. A circuit responsive to the output of the permeability sensor provides an output signal indicating the high coercivity strip when the permeability sensor output is low and indicating a low coercivity strip when the permeability sensor output is high.

  • Patent number: 6545831
    Abstract: This invention discloses a plurality of substantially parallel data arcs disposed on a flat data storage medium. The data arcs include at least two linearly aligned servo-data fields disposed in an inner data arc and an outer data arc with an inter-arc distance. The servo data field disposed on the outer data arc is disposed with an offset from an identical radial-angle position projected from a radial center to the servo data field of the inner data arc. The offset is substantially proportional to the inter-arc distance and substantially proportional to SIN (&thgr;) where &thgr; is an angle between the identical radial-angle position and a linear-alignment direction between the two linearly aligned servo-data fields. Furthermore, the servo-data field on the outer data arc is disposed at a location with the offset from the identical radial-angle position in a direction toward a smaller radial angle projected from the radial center to the servo data field of the inner data arc.

    Abstract: A magnetic write control apparatus transports a medium having a magnetic stripe, until the magnetic stripe reaches a magnetic write position. The apparatus moves a magnetic head and the medium relative to each other, thereby to perform magnetic writing on the magnetic stripe. The magnetic head magnetically writes prescribed data on the magnetic stripe, asynchronously with the relative motion of the magnetic head and the medium.

    Abstract: A head protection device in a data recording circuit Is disclosed in which write-current of a given level that corresponds to a high or low level of coercive force of the magnetic recording portion of a recording medium is provided as an output and supplied to a magnetic head for data recording and reproduction. The data recording circuit comprises an alternate write-current supply portion for alternately providing, by a suitable current switching means, a low write-current corresponding to a low coercivity magnetic head and a high write-current corresponding to a high coercivity magnetic head, a common output portion for providing data to be recorded using a low current or a high current from the alternate write-current supply portion. The low coercivity magnetic head and the high coercivity magnetic head can be at least electrically switched. A current protection portion for a current switching means is provided so as to prevent generation of high write-current at the alternate write-current supply portion.

  • Patent number: 6476991
    Abstract: Methods and apparatus for increasing the density of data storage on a magnetic medium by using variations in positioning of magnetic transitions to encode bits. Conventionally encoded bits are written to the medium as sequences of magnetic transitions according to an encoding standard. Additional bits are encoded on the medium as deviations from a nominal position of magnetic transitions separating conventionally encoded bits. The deviation from the nominal position is within an allowable range of tolerance for the standard followed in encoding the conventionally encoded bits. In order to prevent accumulation of error, additional bits are only encoded in transitions separating a pair of conventionally encoded bits. The first and last transitions of the pair do not have additional bits encoded as deviations of transition locations. This technique allows the encoding of one additional bit for every two conventionally encoded bits.

  • Patent number: 6466384
    Abstract: A device for reading magnetically encoded data on a document, such as a strip of characters printed in magnetic ink along the lower edge of a check, executes a subroutine to determine whether each character, as it is read, is legitimate. This error detection may be done by comparing recognized code patterns with legitimate code patterns, or by comparing a signal representing the strength of the signal derived from the output of the magnetic read head reading the data with a predetermined level. If an error is detected, the magnetically encoded data is read and checked again, as often as need up to a predetermined number of attempts to read the data.
