Sensor are widely used to read magnetic data and to read the magnetic and the optical patterns printed on notes and so on. A multichannel head in accordance with the present invention has plural magnetic cores arranged in a row and a cancellation core for noise removal, the head can detect magnetic characteristics as a whole in a stationary state without depending on the relative speed of the magnetic member with the head, and therefore is least affected by noise. Since one cancellation core is shared by plural magnetic cores, the structure as a whole becomes simple, and the cost of manufacture can be remarkably reduced. Since a magnetic head is combined with optical fibers in an integral structure according to this invention, it can read magnetic patterns and the optical patterns on the same location simultaneously by a parallel operation.

Multichannel magnetic and optical linear head

Primary and secondary coils are wound on a differential type magnetic head, and a low frequency signal is applied on the primary coil. Based on the difference between the output voltages from the head when an object of detection is placed near the magnetic head on the detection side and the output voltage therefrom when an object is not placed near the magnetic head, the magnetization characteristic curve of the magnetic flux and the magnetic field is calculated. Since the magnetization characteristic detection is determined by dividing a magnetic flux by the measured area cross section, once the magnetic flux is determined, a general B-H curve can be simply calculated. The magnetization characteristic measurement device includes a differential type magnetic head portion having plural differential type magnetic heads in linear arrangement which is positioned on or near the magnetic thin film of a detection object. The device can calculate magnetization characteristics of the magnetic thin film by applying a low frequency signal on the magnetic head, successively switching differential output voltages given to a cancellation core of the plural differential magnetic cores by a data converting section into digital data, and conducting software integration by a measured data analyzing section based on the data.

A certification identifying medium such as debit card or credit card comprising a substrate preferably made of a paper material, a bar code band printed or layered on the substrate with a material including a magnetic material provided with a specific coercive force and a magnetic record band disposed on the substrate to magnetically record information of the bar code. A mask band made of a non-magnetic material is applied to the substrate to cover at least the bar code band to prevent the visual observation thereof. The bar code band generally comprises a plurality of bar codes which have the specific coercive force different from each other.

Certification identifying medium

An identification recording data method for an identification medium includes the steps of printing or laminating an information identification bar code strip and then affixing a magnetic recording strip to the identification medium. A data set is encoded into N encoded data using N algorithms. The bar code strip has the N encoded data recorded thereon. The magnetic recording strip has the data set recorded thereon. The N encoded data is decoded and compared with the data set recorded on the magnetic strip. Comparision of the data yields a determination as to the integrity of the identification medium.
