Abstract
In a magnetic sensing head with reduced crossfeed interference circuitry, the winding of each half of a magnetic core of the head is wound in the same direction as the other about the core. Each winding is coupled to an individual differential amplifier and the output of each amplifier is fed to another differential amplifier which provides the head output substantially unaffected by interference signals picked up by the head. Both magnetically coupled and stray capacitive interference are compensated.
