ABSTRACT:
For exact positioning of a magnetic head to various tracks of a magnetic tape by use of a stepping motor, a plurality of motor control steps required in order to position the magnetic head to the various tracks proceeding from a reference position are identified. For the compensation of manufacturing tolerances, individual positional values are identified for every magnetic tape recorder. These positional values indicate a precise position of the magnetic head on the center of the respective track. The positional values are stored in a read-only memory, or are formed by addition of stored standard values and correction values stored in a read-only memory.
