This invention aims to provide a magnetic head for a magnetic reader improved so that the data can be read out from the magnetic storage medium with high security, that is, without an anxiety that the data might be illegally read out and, even if the data is illegally read out, such illegally read out data can not be used by the illegal person. Here is disclosed a magnetic head of a magnetic card reader adapted to read out data stored on a magnetic card, comprising a core with a coil for sensing of the data stored on the card as analog signals, an A/D converter chip adapted to convert the analog signals to corresponding digital signals and a microprocessor adapted to encrypt the digital signals. The A/D converter chip and the microprocessor (IC) are fixed within a housing by means of a synthetic resin.
