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. The reading head is located in a casing pot and has at least one field plate sensor, on which side remote from the face a permanent magnet is placed with a magnetic shunt to the casing pot.
