Abstract
The present invention features a magnetic read head having an IC component provided within or adjacent to the head case. No low-level, analog signals, which are generally highly susceptible to electrical noise, leave the head structure. Power and ground signals are provided to the hybrid head. Digitized data corresponding to encoded information upon the magnetic stripe on a credit card, ID badge, or similar article is provided at output terminals. Decoding is performed by an ASIC or similar device located at the read head. A data strobe signal and/or a magnetic medium detected signal may also be provided by the read head.
