发明名称 Magnetic reading head having a tapered reading opening and/or a tapered reading stylus
摘要 The invention concerns a reading head with a tapered reading opening and/or a tapered reading stylus for reading bar-type, especially passive magnetic information on a data carrier. A high resolution in reading this information with a high output signal is obtained by tapering the reading opening in direction of the end face of the reading head.
