Abstract:
An apparatus for reading, amplifying, and decoding a magnetic signal generated from a magnetically encoded article, said apparatus comprising:a. a housing; b. a substrate mounted within said housing; c. a magnetic read head structure attached to said substrate and comprising a core having a gap and a winding coil for generating a coil output voltage in said winding coil in response to changes in magnetic flux in said core created by the motion of said magnetic read head structure relative to said magnetically encoded article; d. an amplifier electrically connected to said magnetic head structure and mounted to said substrate, said amplifier adapted to receive and amplify said coil output voltage and generate an amplifier output voltage; and e. an IC component electrically connected to said amplifier and mounted to said substrate, said IC component adapted to receive said amplifier output voltage and convert it to a digital signal representative of information encoded in said magnetically encoded article.
